INVERSION-BASED FEED-FORWARD COMPENSATION OF INSPIRATORY TRIGGER DYNAMICS IN MEDICAL VENTILATORS

摘要

A ventilator and method of ventilator control. The ventilator includes a pneumatic system (22) for providing and receiving breathing gas, and a controller (50) operatively coupled with the pneumatic system. The controller employs closed-loop control to provide positive breathing assistance to a patient. Supplemental feed-forward compensatory assistance is also provided, in addition to and independently of that commanded by the closed-loop control. The supplemental assistance may be determined, set or selected based on a ventilator parameter and/or an operator parameter, and/or as an automatic ongoing compensatory mechanism responding to varying patient respiratory demand.
