Pressure Support System with Automatic Comfort Feature Modification
First Claim
1. A pressure support system comprising:
- a pressure generating system adapted to generate a pressurized flow of gas;
a patient circuit coupled to the pressure generating system and adapted to communicate the flow of gas to an airway of a patient;
a controller operatively coupled to the pressure generating system, wherein the controller receives a treatment set point from an input source and is programmed to determine an adjusted treatment set point based on the treatment set point and a comfort feature function, wherein the comfort feature function is not based on a physiological condition of such a patient, and wherein the controller controls the operation of the pressure generating system based on the adjusted treatment set point.

Abstract
A pressure support system that delivers a flow of gas to a patient'"'"'s airway via a pressure generating system and a patient circuit. A controller receives a treatment set point from an input source and determines an adjusted treatment set point based on the treatment set point and a comfort feature function, which in one embodiment, is not based on a physiological condition of such a patient. In another embodiment, the controller provides a respiratory treatment therapy during a therapy session based on the treatment set point and the comfort feature, which is modified automatically during a therapy session without user intervention based on a comparison of the treatment set point to a treatment set point variable. The controller controls the operation of the pressure generating system based on the adjusted treatment set point or the combination of the treatment set point and the comfort feature.
