Methods: 70 patients with severe tracheal intubation admitted from April 2023 to November 2023 were randomly divided into observation group and control group, with 35 cases in each group. The observation group received CQI-based balloon pressure management nursing, and the control group received routine nursing. The pass rate of balloon pressure control, arterial partial oxygen pressure (PaO2), circulatory function (heart rate, systolic blood pressure, diastolic blood pressure) and the rate of airway related complications were compared between the two groups. Results: The qualified rate of airbag pressure control in observation group was significantly higher than that in control group (94.29% vs. 71.43%, P 2 in observation group (93.12 ± 2.56 mmHg) was significantly higher than that in control group (89.45 ± 5.12 mmHg, P < 0.05). In terms of circulatory function, the heart rate, systolic blood pressure and diastolic blood pressure of observation group were significantly better than those of control group (P < 0.05). No serious complications occurred in the observation group, and 1 case of airway mucosal injury occurred in the control group. Conclusion: CQI nursing intervention can significantly improve the effect of balloon pressure management in patients with tracheal intubation, improve respiratory and circulatory functions, and reduce the incidence of airway related complications, which has important clinical application value.展开更多
