METHODS AND SYSTEMS FOR ADJUSTING TIDAL VOLUME DURING VENTILATION
First Claim
Patent Images
1. A method for ventilating a patient with a ventilator comprising:
- delivering a tidal volume to a patient;
monitoring at least one patient parameter;
estimating at least one patient compliance based at least on the at least one monitored parameter;
adjusting the tidal volume to form an adjusted tidal volume based at least on the at least one patient compliance; and
delivering the adjusted tidal volume to the patient.

Abstract
This disclosure describes systems and methods for ventilating a patient with a tidal volume that adjusts based on patient compliance. The disclosure describes a novel breath type or setting for existing breath types, that automatically and continuously varies the delivered tidal volume based on patient compliance and/or other monitored parameters.

17. 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 at least one monitored parameter; a compliance module that estimates at least one patient compliance based at least on the output; a tidal volume module that determines that a delivered tidal volume should be changed based at least on the at least one patient compliance and adjusts the tidal volume based at least on the at least one patient compliance to form an adjusted tidal volume; and a processor communicatively coupled with the pressure generating system, the one or more sensors, the compliance module, and the tidal volume module. - View Dependent Claims (18, 19, 20)
