Abstract:
1. A ventilator system comprising: a pressure generating system adapted to generate a flow of breathing gas; a ventilation tubing system including a patient interface for connecting the pressure generating system to a patient; one or more sensors operatively coupled to at least one of the pressure generating system, the patient, and the ventilation tubing system, wherein at least one sensor is capable of generating an output indicative of an inspiration flow; an effort-based ventilation module that calculates at least one target pressure based on at least one measured inspiration flow and causes the pressure generating system to deliver the at least one target pressure to the patient during inhalation; and a transitory ventilation support module provides a support trajectory for an effort-based delivered breath, the transitory ventilation support module causes the pressure generating system to deliver a control pressure to the patient after a patient initiated trigger is detected for a predetermined amount of time unless the at least one calculated target pressure is greater than a set control pressure during the predetermined amount of time, then a pressure delivered to the patient is determined by the effort-based ventilation module.
