阻塞性肺气肿患者最大跨膈压、膈肌肌电图检查

Examination of Maximum Transdiaphragmatic Pressure, Diaphragm Electromyography in Patients with Obstructive Emphysema

本文介绍了最大跨膈压(Pdimax)、膈肌肌电图(EMGdi)检查方法及16例阻塞性肺气肿患者的检查结果,并与肺功能、血气指标进行相关分析,结果表明:Pdimax与PaCO_2、RV/TLC、FRC相对值显著负相关,与VC、IG、FVC、MVV显著正相关。讨论了膈肌检查的影响因素及其临床应用价值。

This paper reported the methods and results of maximum transdiaphragmatic pressure (Pdi max) and diaphragm electromyography (EMGdi) in 16 patients with obstructive emphysema. A correlation analysis showed that Pdi max is negatively related to Paco_2 FRC%, and positively to VC, IG, FVC and MVV closely. Diaphragmatic fatigue was induced by inspiratory resistive loaded breathing with the parameters of 60% Pdi max and 5 minutes lasting. The influencial effecta and clinical value of diaphragm examination were discussed.
