PROBLEM TO BE SOLVED: To use myoelectrical activity of the diaphragm or other respiratory-related muscles to activate and/or to deactivate a seal member. SOLUTION: A system for controlling an air seal between a ventilator air circuit (34) and a patient's respiratory airways, includes: means (18) for modifying the air seal; means (12) for sensing myoelectrical activity of a respiratory-related muscle of a patient so as to yield amyoelectrical signal representative of respiratory effort of the patient; means (20) for analyzing the myoelectrical signal to supply a signal for controlling an air seal; and an air seal controller to drive the means for modifying the air seal corresponding to the air seal control signal so as to (a) seal the air seal between the ventilator air circuit and the patient's respiratory airways during respiratory effort of the patient; and (b) release the air seal between the ventilator air circuit and the patient's respiratory airways during the relaxation of patient's respiratory effort.
