METHODS AND SYSTEMS FOR AN OPTIMIZED PROPORTIONAL ASSIST VENTILATION
First Claim
Patent Images
1. A method for ventilating a patient with a ventilator comprising:
- retrieving a desired patient effort range;
estimating an initial percent support setting based on the desired patient effort range;
calculating a target airway pressure based at least on the initial percent support setting; and
delivering the target airway pressure to a patient.

13. 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 the one or more sensors generate output indicative of an inspiration flow; a support module that estimates an initial percent support setting based at least on a desired patient effort range and calculates at least one adjusted percent support setting based at least on the desired patient effort range, and a current patient effort; and an OPA module, the OPA module calculates an initial target airway pressure based at least on the initial percent support setting, calculates at least one adjusted target airway pressure based at least on an adjusted percent support setting, and utilizes the output indicative of the inspiration flow to determine a patient trigger for delivery of a breath to the patient. - View Dependent Claims (14, 15, 16, 17)

18. A computer-readable medium having computer-executable instructions for performing a method of ventilating a patient with a ventilator, the method comprising:
-
repeatedly retrieving a desired patient effort range; estimating an initial percent support setting based on the desired patient effort range; repeatedly calculating a target airway pressure based at least on the initial percent support setting; and repeatedly delivering the target airway pressure to a patient. - View Dependent Claims (19, 20)
