The objective of the present study was to evaluate the effectiveness of non-invasive ventilation （NIV） in improving blood oxygen content and hemorheology in patients with AMI and hypoxemia. Methods This prospective study enrolled 50 consecutive eligible patients with AMI （aged 72.3 ± 9.5 years）, who had undergone PCI and been administered high-flow oxygen but still had hypoxemia. Blood was taken before NIV and at 0.5, 1, and 2 h after NIV. Blood gases, hemorheological variables including erythrocyte deformability, erythrocyte aggregation, erythrocyte osmotic fragility, membrane fluidity, and oxidative stress level were measured. Results Blood PaO2 increased to normal by 1 h after NIV. Assessed hemorheological variables had all improved and plasma malondialdehyde concentration decreased significantly after 2 h of NIV. Conclusions Our data suggest that NIV can help to improve blood oxygen content, hemorheological status, and minimize plasma lipid peroxidation injury in hypoxemic patients with AMI who have undergone PCI.展开更多

Patients with pulmonary hypertension undergoing surgical procedures such as hemiarthroplasty present a high risk of fatal complications. Nonetheless, there are no widely accepted protocols explaining their perioperative care in great detail. Case presentation: We present a case with an 89-years-old patient, with comorbidities such as GOLD 4D chronic obstructive pulmonary disease (COPD) and, as a consequence of this, severe pulmonary hypertension with signs of right ventricular dysfunction, thus requiring of pulmonary vasodilator, that has suffered a subcapital hip fracture requiring urgent surgery. Surgery is carried out successfully, under regional lumbar-sacral plexus block and sedation assisted by non-invasive ventilation. Conclusion: Multidisciplinary specialized treatment, preoperative optimization, as well as the careful selection of both the surgical and anesthetic techniques to be used, are among the strategies that improve the perioperative outcome in patients with pulmonary hypertension with right ventricle systolic dysfunction. Regional lumbar-sacral plexus block plus sedation is a technique that maintains hemodynamic stability;however, these patients require advance measures and postoperative monitoring under intensive care.展开更多

Methods: A total of 68 patients with COPD complicated by severe pneumonia who were treated in the hospital between November 2015 and April 2017 were collected, retrospectively analyzed and then divided into the group A (n=35) who received noninvasive positive pressure ventilation and the group B (n=33) who received lung lavage via fiber bronchoscope combined with non-invasive positive pressure ventilation. The differences in arterial blood gas and serum index levels were compared between the two groups before and after treatment. Results: Before treatment, there was no statistically significant difference in arterial blood gas index levels as well as serum contents of inflammatory mediators, stress hormones and myocardial enzyme spectrum indexes between the two groups. After treatment, arterial blood gas indexes PH and PaO2 levels of group B were higher than those of group A;serum inflammatory mediators HMGB1, PCT and hs-CRP contents were lower than those of group A;serum stress hormones Cor, AngⅠ and AngⅡcontents were lower than those of group A;serum myocardial enzyme spectrum indexesα-HBDH and cTn-Ⅰ contents were lower than those of group A. Conclusion: Lung lavage via fiber bronchoscope combined with non-invasive positive pressure ventilation can effectively optimize the arterial blood gas levels, reduce systemic inflammatory stress state and protect the myocardial function of patients with COPD complicated by severe pneumonia.展开更多

Methods: To investigate whether such a leak affects FiO2 supplied to the alveoli, we simulated a patient with chronic obstructive pulmonary disorder during NPPV in HMV. In addition, FiO2 was measured in the portion assumed to be the mouth and lungs while setting the flow of the oxygen concentrator and leak amount based on a previous study. Results: FiO2 supplied to the lungs increased statistically significantly upon increasing the amount of leak (P Conclusions: We observed that FiO2 supplied to alveoli can be reduced by a leak in the NPPV mask. Because our results differ from those previously reported, we believe that further studies should reassess the selection of respirators and oxygen concentrators.展开更多

The clinical benefits of pre- and perioperative, non-invasive pressure support ventilation (NIPSV) have up to now not been extensively evaluated. Patients with severely reduced pulmonary function were investigated in this prospective and randomised single centre clinical trial. Methods: Standard pulmonary evaluation was performed in all patients before major lung resection. To predict postoperative pulmonary function, a lung perfusion-ventilation scan was carried out. All patients enrolled in the study were instructed preoperatively on how to use a NIPSV respirator. Af-ter lung resection patients were randomised either for continuation of NIPSV or for standard treatment. Results: Of the 52 patients assessed, 21 patients met the inclusion criteria for the study protocol. Predicted mean postoperative FEV1 was 1.10 L (range 0.92 - 1.27 L). Lobectomy was performed in 14 patients, pneumonectomy in 6 patients and a segmentectomy in 1 patient. No inhospital deaths occurred. Pulmonary complications (reintubation, pneumonia) were more frequent in the NIPSV group than in the control group (3 patients versus 1 patient), without statistical significance (p = 0.31). Conclusions: We observed no mortality and a low morbidity in this high risk group. Postoperative continuation of NIPSV had no beneficial effect on the clinical outcome. Preoperative conditioning with NIPSV, however, seems to be a suitable tool for patients with severely impaired pulmonary function. This study may serve therefore as basis for further investigations for the potential clinical benefits of prophylactic NIPSV in major lung surgery.展开更多

Methods: 120 patients with severe pulmonary infection admitted from February 2019 to August 2020 were included. They were equally divided into experimental group (n=60) and reference group (n=60) in the form of random number table. The reference group received routine treatment, while the experimental group received non-invasive positive pressure ventilation on the basis of the reference group. The total effective rate, oxygen partial pressure, CO2 partial pressure, respiratory rate and inflammatory factors of the two groups before and after treatment were recorded. Results: the total clinical effective rate of the experimental group was higher than that of the reference group, and there was a difference between the two groups (P < 0.05). Before treatment, there was no difference in oxygen partial pressure, CO2 partial pressure, respiratory frequency and inflammatory factors between the two groups (P > 0.05). After treatment, the partial pressure of oxygen in the experimental group was higher than that in the reference group, while the partial pressure of CO2, respiratory rate, CRP, IL-6 and TNF-α contents in the experimental group were all lower than those in the reference group, with differences in comparison between the groups (P < 0.05). The total adverse reaction rate of the experimental group was lower than that of the conventional group, and there was a statistical difference between the two groups (P<0.05). Conclusion: non-invasive positive pressure ventilation for patients with severe pulmonary infection is more conducive to the recovery of various indicators and the overall treatment effect is significant.展开更多

The nursing staff adopted conventional methods to carry out the nursing observation of the patients in the control group. On this basis, combined with the non-invasive positive pressure ventilation pressure sore nursing intervention model, the nursing research of the observation group was carried out. Then, the occurrence probability of pressure sore and nursing satisfaction of the patients in the two groups were compared. For the two groups of patients' nursing satisfaction, the observation group patients' nursing satisfaction was 97.65%, significantly higher than the control group 80.00%, while the observation group's pressure sore incidence rate was 2.35%, the control group's pressure sore incidence rate was 21.18%, data comparison, the observation group's pressure sore incidence rate was significantly lower, the difference between the groups was statistically significant (p < 0.05). It can be seen from this that in order to do a good job in the nursing of critically ill patients with COPD, it is extremely critical for the nursing staff to adopt the non-invasive positive pressure ventilation pressure sore nursing mode. On the basis of keeping close contact with the patients, the occurrence rate of pressure sores can be fundamentally reduced, and the nursing satisfaction of the patients can be comprehensively improved.展开更多

Methods: 80 cases of patients admitted to our hospital diagnosed with severe pulmonary infection were selected as the subjects of this study. The treatment time range was from January 2016 to December 2020. Patients in the control group were treated with conventional treatment measures, while the observation group was treated with non-invasive positive pressure ventilation, and the treatment results were compared. Results: in terms of treatment, the observation group had good curative effect, and the statistical results of oxygen partial pressure, carbon dioxide partial pressure and respiratory rate were different (P < 0.05). Meanwhile, in the comparison of the levels of CRP, TNF-α, IL-6 and IL-8 inflammatory cytokines, the data of the observation group were better than the control group, and the difference was statistically significant. Finally, the total effective rate of the observation group was 95.0%, while that of the control group was 87.5%, and the comparison was statistically significant. Conclusion: the use of non-invasive positive pressure ventilation program has good curative effect, and helps to improve the patients' qi and blood indexes and respiratory rate. At the same time, it helps to alleviate the inflammatory reaction, and patients' rehabilitation treatment is consolidated, which has the value of generalization.展开更多
文摘Hyaline Membrane Disease(HMD)in newborns,also known as neonatal respiratory distress syndrome,is a common critical illness in premature infants,with an incidence inversely correlated with gestational age,posing a serious threat to the life and health of newborns.This paper systematically reviews the core pathogenesis of HMD,focusing on the abnormal metabolism of pulmonary surfactant(PS),genetic factors,immature lung development,and the synergistic effects of inflammatory oxidative stress.It highlights the advances in non-invasive ventilation(NIV)therapy for HMD,including the mechanisms of action,clinical application effects,and optimization strategies of mainstream modalities such as nasal continuous positive airway pressure ventilation(NCPAP),nasal intermittent positive pressure ventilation(NIPPV),and heated humidified high-flow nasal cannula ventilation(HHHFNC).The aim is to provide references for standardized clinical treatment.

文摘Patients with acute exacerbation of chronic obstructive pulmonary disease(COPD)often suffer from respiratory failure and require respiratory support therapy.High-flow nasal cannula oxygen therapy(HFNC)and non-invasive positive pressure ventilation(NIPPV)are commonly used non-invasive respiratory support methods.HFNC can provide precisely heated and humidified high-flow oxygen,reducing dead space and increasing alveolar ventilation.NIPPV can supply stable high-concentration oxygen and improve gas exchange.This article reviews the application of HFNC and NIPPV in the acute exacerbation stage of COPD,aiming to provide references for reasonable clinical selection.
文摘Background Hypoxemia sometimes occurs in the emergency room in the patients with acute myocardial infarction （AMI） after percutaneous coronary intervention （PCI）, even in those with administration of conventional high-flow oxygen inhalation. The objective of the present study was to evaluate the effectiveness of non-invasive ventilation （NIV） in improving blood oxygen content and hemorheology in patients with AMI and hypoxemia. Methods This prospective study enrolled 50 consecutive eligible patients with AMI （aged 72.3 ± 9.5 years）, who had undergone PCI and been administered high-flow oxygen but still had hypoxemia. Blood was taken before NIV and at 0.5, 1, and 2 h after NIV. Blood gases, hemorheological variables including erythrocyte deformability, erythrocyte aggregation, erythrocyte osmotic fragility, membrane fluidity, and oxidative stress level were measured. Results Blood PaO2 increased to normal by 1 h after NIV. Assessed hemorheological variables had all improved and plasma malondialdehyde concentration decreased significantly after 2 h of NIV. Conclusions Our data suggest that NIV can help to improve blood oxygen content, hemorheological status, and minimize plasma lipid peroxidation injury in hypoxemic patients with AMI who have undergone PCI.
文摘Objective:To evaluate the in-hospital outcome of moderate to severe COVID-19 patients admitted in High Dependency Unit(HDU)in relation to invasive vs.non-invasive mode of ventilation.Methods:In this study,the patients required either non-invasive[oxygen≤10 L/min or>10 L/min through mask or nasal prongs,rebreather masks and bilevel positive airway pressure(BiPAP)]or invasive ventilation.For analysis of 30-day in hospital mortality in relation to use of different modes of oxygen,Kaplan Meier and log rank analyses were used.In the end,independent predictors of survival were determined by Cox regression analysis.Results:Invasive ventilation was required by 15.1%patients while 84.9%patients needed non-invasive ventilation.Patients with evidence of thromboembolism,high inflammatory markers and hypoxemia mainly required invasive ventilation.The 30-day in hospital mortality was 72.7%for the invasive group and 12.9%for the non-invasive group(1.8%oxygen<10 L/min,0.9%oxygen>10 L/min,3.6%rebreather mask and 4.5%BiPAP).The median time from hospital admission to outcome was 7 days for the invasive group and 18 days for the non-invasive group(P<0.05).Age,presence of co-morbidities,number of days requiring oxygen,rebreather,BiPAP and invasive ventilation were independent predictors of outcome.Conclusions:Invasive mechanical ventilation is associated with adverse outcomes possibly due to ventilator associated lung injury.Thus,protective non-invasive ventilation remains the necessary and safe treatment for severely hypoxic COVID-19 patients.
文摘Objective:To compare the survival and length of stay of invasive ventilation(IV)with those of non-invasive ventilation(NIV)in patients with COVID-19 acute respiratory distress syndrome in a single hospital from May 2020 to March 2021.Methods:After obtaining approval from the Hospital Director,the data of COVID-19 patients including demographics,type of respiratory support(non-invasive ventilation or invasive ventilation),duration of ventilation,length of stay,discharge,and death were collected and analyzed.Results:Out of the 152 patients identified,134 patients were analyzed.The median intubation days were 10.0(Q1:3.5,Q3:13.5)in the IV group and 0.0(Q1:0.0,Q3:0.0)days in the NIV-only group.Out of the 101 patients who received NIV,43 patients were subsequently intubated due to failure of NIV.Of the 63 patients(47.01%)who died,22(66.66%)were from the IV group and 40(92.02%)were from the NIV-followed-by-intubation group,and 1(1.72%)were from the NIV-only group.Multivariate analysis showed that the presence of a respiratory comorbidity(OR=16.56,95%CI=1.56-175.48,P=0.02)was an independent predictor of survival.Conclusions:Respiratory co-morbidity is a significant adverse predictor of survival outcome.The decision on the type of respiratory support should be made on a patient-to-patient basis.
文摘Background: Pulmonary hypertension is defined as a mean arterial pressure in the pulmonary artery exceeding 20 mm Hg at rest, measured by means of right heart catheterization. Patients with pulmonary hypertension undergoing surgical procedures such as hemiarthroplasty present a high risk of fatal complications. Nonetheless, there are no widely accepted protocols explaining their perioperative care in great detail. Case presentation: We present a case with an 89-years-old patient, with comorbidities such as GOLD 4D chronic obstructive pulmonary disease (COPD) and, as a consequence of this, severe pulmonary hypertension with signs of right ventricular dysfunction, thus requiring of pulmonary vasodilator, that has suffered a subcapital hip fracture requiring urgent surgery. Surgery is carried out successfully, under regional lumbar-sacral plexus block and sedation assisted by non-invasive ventilation. Conclusion: Multidisciplinary specialized treatment, preoperative optimization, as well as the careful selection of both the surgical and anesthetic techniques to be used, are among the strategies that improve the perioperative outcome in patients with pulmonary hypertension with right ventricle systolic dysfunction. Regional lumbar-sacral plexus block plus sedation is a technique that maintains hemodynamic stability;however, these patients require advance measures and postoperative monitoring under intensive care.
文摘Objective:To analyze key factors associated with the failure of non-invasive ventilation(NIV)in patients with acute exacerbations of chronic obstructive pulmonary disease(AECOPD)complicated by type II respiratory failure.Methods:A total of 122 patients with AECOPD and type II respiratory failure admitted to Gaoyou People’s Hospital between January 2020 and June 2023 were selected for the study.Upon admission,all patients received ECG monitoring and NIV,along with comprehensive therapies such as anti-infective treatment,antispasmodics,bronchodilators,and expectorants.NIV was provided using the S/T mode,with ventilator parameters adjusted based on the patient’s respiratory status and blood gas analysis results.Clinical data were retrospectively analyzed from electronic medical records.Results:Out of the 122 patients,30 experienced NIV failure,accounting for 24.59%.Significant differences were observed in C-reactive protein(CRP),pH,and partial pressure of arterial carbon dioxide(PaCO_(2))between patients with successful and failed NIV outcomes(P<0.05).There were no statistically significant differences in gender,age,arterial oxygen partial pressure(PaO_(2)),neutrophil count(NEUT),procalcitonin(PCT),albumin(ALB),or tidal volume between the two groups(P>0.05).Logistic regression analysis confirmed that CRP,pH,and PaCO_(2)were significant risk factors for NIV failure(P<0.05).Conclusion:CRP,pH,and PaCO_(2)are independent risk factors influencing NIV failure.

文摘BACKGROUND The coronavirus disease 2019(COVID-19)pandemic has become an immense public health burden,first in China and subsequently worldwide.Developing effective control measures for COVID-19,especially measures that can halt the worsening of severe cases to a critical status is of urgent importance.CASE SUMMARY A 52-year-old woman presented with a high fever(38.8°C),chills,dizziness,and weakness.Epidemiologically,she had not been to Wuhan where COVID-19 emerged and did not have a family history of a disease cluster.A blood test yielded a white blood cell count of 4.41×109/L(60.6±2.67%neutrophils and 30.4±1.34%lymphocytes).Chest imaging revealed bilateral ground-glass lung changes.Based on a positive nasopharyngeal swab nucleic acid test result and clinical characteristics,the patient was diagnosed with COVID-19.Following treatment with early non-invasive ventilation and a bundle pharmacotherapy,she recovered with a good outcome.CONCLUSION Early non-invasive ventilation with a bundle pharmacotherapy may be an effective treatment regimen for the broader population of patients with COVID-19.
文摘Over the last 20 years, the application of non-invasive ventilation （NIV） in China has progressively increased both in the hospital and extrahospital setting. The history of the NIV and its increasing spread in the clinical practice over China are one of the most important results of the cooperation between medicine and non-invasive mechanic technology.
文摘Optimal initial non-invasive management of acute hypoxemic respiratory failure(AHRF),of both coronavirus disease 2019(COVID-19)and non-COVID-19 etiologies,has been the subject of significant discussion.Avoidance of endotracheal intubation reduces related complications,but maintenance of spontaneous breathing with intense respiratory effort may increase risks of patients’self-inflicted lung injury,leading to delayed intubation and worse clinical outcomes.High-flow nasal oxygen is currently recommended as the optimal strategy for AHRF management for its simplicity and beneficial physiological effects.Non-invasive ventilation(NIV),delivered as either pressure support or continuous positive airway pressure via interfaces like face masks and helmets,can improve oxygenation and may be associated with reduced endotracheal intubation rates.However,treatment failure is common and associated with poor outcomes.Expertise and knowledge of the specific features of each interface are necessary to fully exploit their potential benefits and minimize risks.Strict clinical and physiological monitoring is necessary during any treatment to avoid delays in endotracheal intubation and protective ventilation.In this narrative review,we analyze the physiological benefits and risks of spontaneous breathing in AHRF,and the characteristics of tools for delivering NIV.The goal herein is to provide a contemporary,evidence-based overview of this highly relevant topic.
文摘Objective:To investigate the application effect of intelligent empowerment standardized airway management process in patients receiving mechanical ventilation.Methods:A retrospective analysis was conducted on the clinical data of 79 EICU inpatients who underwent tracheal intubation and mechanical ventilation treatment at our hospital from January 2023 to May 2025.The patients were divided into a control group(conventional airway management process,n=40)and a study group(intelligent empowerment standardized airway management process,n=39)based on the intervention protocols they received.Oral health scores,dental plaque index,oral odor,serum inflammatory markers[C-reactive protein(CRP),procalcitonin(PCT)],clinical pulmonary infection score(CPIS),as well as the incidence of ventilator-associated pneumonia(VAP),duration of mechanical ventilation,and length of stay in the EICU were assessed before and after treatment.Results:The baseline values of all indicators were consistent between the two groups before intervention(p>0.05).After corresponding interventions,both groups showed significant improvements in Beck oral health scores,dental plaque index,and oral odor,with more pronounced improvements observed in the study group(p<0.05).After the intervention,the research group showed a significant decrease in serum CRP and PCT levels,as well as CPIS scores(p<0.05).In contrast,the control group experienced an increase in these three indicators to a certain extent(p<0.05).Moreover,the incidence of ventilator-associated pneumonia(VAP),duration of mechanical ventilation,and length of stay in the EICU were all lower in the research group compared to the control group,while the nurse’s compliance rate with the protocol was higher in the research group(p<0.05).Conclusion:The standardized airway management protocol empowered by intelligent technology can significantly improve nursing compliance,benefit oral health status,reduce the risk of pulmonary infection and systemic inflammation levels,and promote rapid patient recovery,demonstrating considerable potential for widespread adoption.
文摘Severe acute pancreatitis(SAP)can induce acute respiratory distress syndrome(ARDS)and abdominal compartment syndrome(ACS).Although prone position ventilation(PPV)can improve outcomes in patients with ARDS,there is significant controversy regarding its concurrent use with ACS owing to concerns of increased risk of intra-abdominal pressure(IAP).[1]We present a case of successful PPV application without adverse eff ects.
文摘Objective: To discuss the effect of lung lavage via fiber bronchoscope combined with non-invasive positive pressure ventilation on the blood gas results and systemic state of patients with COPD complicated by severe pneumonia. Methods: A total of 68 patients with COPD complicated by severe pneumonia who were treated in the hospital between November 2015 and April 2017 were collected, retrospectively analyzed and then divided into the group A (n=35) who received noninvasive positive pressure ventilation and the group B (n=33) who received lung lavage via fiber bronchoscope combined with non-invasive positive pressure ventilation. The differences in arterial blood gas and serum index levels were compared between the two groups before and after treatment. Results: Before treatment, there was no statistically significant difference in arterial blood gas index levels as well as serum contents of inflammatory mediators, stress hormones and myocardial enzyme spectrum indexes between the two groups. After treatment, arterial blood gas indexes PH and PaO2 levels of group B were higher than those of group A;serum inflammatory mediators HMGB1, PCT and hs-CRP contents were lower than those of group A;serum stress hormones Cor, AngⅠ and AngⅡcontents were lower than those of group A;serum myocardial enzyme spectrum indexesα-HBDH and cTn-Ⅰ contents were lower than those of group A. Conclusion: Lung lavage via fiber bronchoscope combined with non-invasive positive pressure ventilation can effectively optimize the arterial blood gas levels, reduce systemic inflammatory stress state and protect the myocardial function of patients with COPD complicated by severe pneumonia.

文摘Introduction: During the application of non-invasive positive pressure ventilation (NPPV) therapy in home mechanical ventilation (HMV), leaks in the NPPV mask may occur owing to the position of the mask due to conditions such as skin disorders. Methods: To investigate whether such a leak affects FiO2 supplied to the alveoli, we simulated a patient with chronic obstructive pulmonary disorder during NPPV in HMV. In addition, FiO2 was measured in the portion assumed to be the mouth and lungs while setting the flow of the oxygen concentrator and leak amount based on a previous study. Results: FiO2 supplied to the lungs increased statistically significantly upon increasing the amount of leak (P Conclusions: We observed that FiO2 supplied to alveoli can be reduced by a leak in the NPPV mask. Because our results differ from those previously reported, we believe that further studies should reassess the selection of respirators and oxygen concentrators.
文摘Background and purpose: Patients with severely impaired pulmonary function have an increased operative risk for major lung resection. The clinical benefits of pre- and perioperative, non-invasive pressure support ventilation (NIPSV) have up to now not been extensively evaluated. Patients with severely reduced pulmonary function were investigated in this prospective and randomised single centre clinical trial. Methods: Standard pulmonary evaluation was performed in all patients before major lung resection. To predict postoperative pulmonary function, a lung perfusion-ventilation scan was carried out. All patients enrolled in the study were instructed preoperatively on how to use a NIPSV respirator. Af-ter lung resection patients were randomised either for continuation of NIPSV or for standard treatment. Results: Of the 52 patients assessed, 21 patients met the inclusion criteria for the study protocol. Predicted mean postoperative FEV1 was 1.10 L (range 0.92 - 1.27 L). Lobectomy was performed in 14 patients, pneumonectomy in 6 patients and a segmentectomy in 1 patient. No inhospital deaths occurred. Pulmonary complications (reintubation, pneumonia) were more frequent in the NIPSV group than in the control group (3 patients versus 1 patient), without statistical significance (p = 0.31). Conclusions: We observed no mortality and a low morbidity in this high risk group. Postoperative continuation of NIPSV had no beneficial effect on the clinical outcome. Preoperative conditioning with NIPSV, however, seems to be a suitable tool for patients with severely impaired pulmonary function. This study may serve therefore as basis for further investigations for the potential clinical benefits of prophylactic NIPSV in major lung surgery.
文摘Objective:This study aims to evaluate the clinical efficacy of non-invasive positive pressure ventilation(NIPPV)in patients with severe bronchial asthma combined with respiratory failure.Methods:90 patients with severe bronchial asthma combined with respiratory failure between September 2022 and December 2023 were selected for the study and randomly divided into the experimental group(NIPPV-assisted treatment)and the control group.The differences between the two groups were compared in terms of total effective rate of treatment,days of clinical symptom disappearance,days of hospitalization,lung function indexes,incidence of adverse reactions,and quality of life.Results:Patients in the experimental group had a significantly higher total effective rate of treatment(97.78%)than the control group(75.56%).In terms of pulmonary function indexes,patients in the experimental group showed significant improvement after treatment,especially the increase in forced expiratory volume and forced vital capacity,while these improvements were not as obvious in the control group.In addition,the incidence of adverse reactions was significantly lower in the experimental group than in the control group,suggesting that the application of NIPPV is relatively safe.Quality of life assessment also showed that patients in the experimental group had significantly better quality of life than the control group after treatment.Conclusion:This study demonstrated the effectiveness of NIPPV as an adjunctive treatment for severe bronchial asthma combined with respiratory failure.NIPPV can improve lung function,reduce the incidence of adverse effects,increase the overall effectiveness of the treatment,and contribute to the improvement of patients'quality of life.Therefore,NIPPV should be regarded as an effective and safe treatment in clinical management,especially in patients with severe bronchial asthma combined with respiratory failure,where its application has potential clinical significance.
文摘Objective: to analyze the effect of non-invasive positive pressure ventilation in patients with severe pulmonary infection. Methods: 120 patients with severe pulmonary infection admitted from February 2019 to August 2020 were included. They were equally divided into experimental group (n=60) and reference group (n=60) in the form of random number table. The reference group received routine treatment, while the experimental group received non-invasive positive pressure ventilation on the basis of the reference group. The total effective rate, oxygen partial pressure, CO2 partial pressure, respiratory rate and inflammatory factors of the two groups before and after treatment were recorded. Results: the total clinical effective rate of the experimental group was higher than that of the reference group, and there was a difference between the two groups (P < 0.05). Before treatment, there was no difference in oxygen partial pressure, CO2 partial pressure, respiratory frequency and inflammatory factors between the two groups (P > 0.05). After treatment, the partial pressure of oxygen in the experimental group was higher than that in the reference group, while the partial pressure of CO2, respiratory rate, CRP, IL-6 and TNF-α contents in the experimental group were all lower than those in the reference group, with differences in comparison between the groups (P < 0.05). The total adverse reaction rate of the experimental group was lower than that of the conventional group, and there was a statistical difference between the two groups (P<0.05). Conclusion: non-invasive positive pressure ventilation for patients with severe pulmonary infection is more conducive to the recovery of various indicators and the overall treatment effect is significant.
文摘For the critically ill patients with COPD, in order to do a good job of nursing, the article investigates the application effect of nursing intervention on pressure sore caused by non-invasive positive pressure ventilation. 170 patients in our hospital were selected and the staffs were randomly divided into control group and observation group with equal number of cases. The nursing staff adopted conventional methods to carry out the nursing observation of the patients in the control group. On this basis, combined with the non-invasive positive pressure ventilation pressure sore nursing intervention model, the nursing research of the observation group was carried out. Then, the occurrence probability of pressure sore and nursing satisfaction of the patients in the two groups were compared. For the two groups of patients' nursing satisfaction, the observation group patients' nursing satisfaction was 97.65%, significantly higher than the control group 80.00%, while the observation group's pressure sore incidence rate was 2.35%, the control group's pressure sore incidence rate was 21.18%, data comparison, the observation group's pressure sore incidence rate was significantly lower, the difference between the groups was statistically significant (p < 0.05). It can be seen from this that in order to do a good job in the nursing of critically ill patients with COPD, it is extremely critical for the nursing staff to adopt the non-invasive positive pressure ventilation pressure sore nursing mode. On the basis of keeping close contact with the patients, the occurrence rate of pressure sores can be fundamentally reduced, and the nursing satisfaction of the patients can be comprehensively improved.
文摘Objective: in this study, patients with severe pulmonary infection were treated with non-invasive positive pressure ventilation, so as to further control the development of the disease and improve pulmonary function indexes. Methods: 80 cases of patients admitted to our hospital diagnosed with severe pulmonary infection were selected as the subjects of this study. The treatment time range was from January 2016 to December 2020. Patients in the control group were treated with conventional treatment measures, while the observation group was treated with non-invasive positive pressure ventilation, and the treatment results were compared. Results: in terms of treatment, the observation group had good curative effect, and the statistical results of oxygen partial pressure, carbon dioxide partial pressure and respiratory rate were different (P < 0.05). Meanwhile, in the comparison of the levels of CRP, TNF-α, IL-6 and IL-8 inflammatory cytokines, the data of the observation group were better than the control group, and the difference was statistically significant. Finally, the total effective rate of the observation group was 95.0%, while that of the control group was 87.5%, and the comparison was statistically significant. Conclusion: the use of non-invasive positive pressure ventilation program has good curative effect, and helps to improve the patients' qi and blood indexes and respiratory rate. At the same time, it helps to alleviate the inflammatory reaction, and patients' rehabilitation treatment is consolidated, which has the value of generalization.
