ABSTRACT:
The movements of an exhalation valve are damped at a variable rate to control pressure oscillations within a ventilation system. The exhalation valve is damped as a function of its velocity at a rate that is a function of a variable linked to the pneumatic state of the system, to provide a feedback signal to the valve driver.
