Sunto
The effect of an added expiratory resistive load on the decay rate of inspiratory muscle pressure was studied in 4 subjects during the postinspiratory period of zero flow occurring under discontinuous inspiratory elastic load. The decay rate was not increased by expiratory resistive loads, i.e. when the braking action of inspiratory muscles was no longer required. This result was confirmed by transdiaphragmatic pressure measurements in one subject without discontinuous inspiratory elastic load. Hence, in conscious man the persistent activity of the inspiratory muscles during expiration is not controlled by a mechanism sensing the decrease of the expiratory flow produced by a resistive load.
