Factors altering diaphragmatic contractility

, 1984
Factors altering contractility of the diaphragm were investigated in dogs. Contractility was assessed by analysis of transdiaphragmatic pressure (Pdi) generated during supramaximal phrenic stimulation at different frequencies and during spontaneous ...
