摘要
对10例肺通气功能正常、10例大致正常及30例慢性阻塞性肺疾病(COPD)患者进行F-V曲线测定,并由IBM-286微机分析计算吸气部分(MIFV)和呼气部分(MEFV)各指标值,同时用改良的Black法测定口腔最大呼气压(MEP)和口腔最大吸气压(MIP)。测定结果经相关分析发现,MEFV和MIFV多数指标实测值(如FIV、VCin、PIF、AIX、MMIF、PIFV、VI75、VI50、VI25、FIV 0.5、FIV 1.0、FVC、VC、PEF、AEX、MMEF、PEFV、VE75、VE50、VE25、FEV 0.5、FEV 1.0等指标)与MEP和MIP明显相关。因此可用F-V曲线一些指标来评价呼吸肌力的强度。经F-V时间容量分析可了解呼吸肌驱动力变化情况及肺组织呼吸动力学变化机制。
In the laboratory,the tests of F-V were performed in 20 persons with normal pulmonary funtion and 30 COPD paitents in relaxation period. Simultanously MEP and MIP were measured by improved Black method. The results were analysed by IBM computer. The indexes had apparent correlation between MEP, MIP and F-V curve(e. g. FIV, VCin.PIF, AIX,MMIF, VI75, VI50, VI25,FIV0. 5, FIV1. 0,FVC,VC,PEF,AEX,MMEF,PEFV,VE75,VE50,VE25,FEV0. 5,FEV1. 0). Therefore, the contractility intensity of respiratory muscles could be evaluated by F-V curve. The changes of punch motive force of respiratory muscles and changes of respiratory motivity of lung tissue by analysing time-volume of F-V curve were observed.
