Abstract:

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 Pdimax is negatively related to PaCO2, FRC%, and positively to VC, IC, FVC and MVV closely. Diaphragmatic fatigue was induced by inspiratory resistive loaded breathing with the parameters of 60% Pdimax and 5 minutes lasting. The influential effects and clinical value of diaphragm examination were discussed.
