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, by the ventilator, a desired patient effort range;
estimating, by the ventilator, an initial percent support setting based on at least a patient effort value in the desired patient effort range;
calculating, by the ventilator, a target airway pressure based at least on the initial percent support setting; and
delivering, by the ventilator, the target airway pressure to the patient.

13. 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 at least a patient effort value in 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 the patient. - View Dependent Claims (14, 15)
