Abstract
The systems and methods include providing, displaying, and/or utilizing leak estimation during ventilation of a patient with a ventilator. The systems and methods include providing, displaying, and/or utilizing internal leak estimation, total leak estimation, and/or external leak estimation during ventilation of a patient with a ventilator.
Claims19
-17. (canceled)
A ventilator system comprising:
- a pressure generating system that generates a flow of breathing gas;
- a ventilation tubing system including a patient interface for connecting the pressure generating system to a patient;
- sensors operatively coupled to the ventilation tubing system, the sensors include a proximal sensor and at least one of an inspiratory sensor and an expiratory sensor, wherein the sensors generate output indicative of at least one of flow and pressure;
- and
- an internal leak module that estimates an internal leak flow using at least sensor output from the proximal sensor.
2 more elements
A non-transitory computer-readable medium having computer-executable instructions executed by a processor of a controller, the controller comprising:
- an internal leak module that estimates internal leak flow based at least on sensor output from a proximal sensor;
- and
- a total leak module that estimates total leak flow based at least on output from at least one of an inspiratory sensor and an expiratory sensor.
