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; and
a controller operatively coupled to the pressure generating system, wherein the controller is configured to;
receive a treatment set point from an input source in accordance with a therapy mode, wherein the therapy mode spans at least one or more respiratory cycles;
determine an adjusted treatment set point based on the treatment set point and a comfort feature function, wherein activation of the comfort feature function results in the adjusted treatment set point being implemented in place of the received treatment set point, wherein activation of the comfort feature function is based on one or more of time spent in the therapy mode, and/or time elapsed since activation of the pressure support system; and
control operation of the pressure generating system based on the adjusted treatment set point for at least one complete respiratory cycle responsive to the comfort feature function being activated.

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.

10. 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; and a controller operatively coupled to the pressure generating system, wherein the controller is configured to; receive a treatment set point from an input source in accordance with a therapy mode, wherein the therapy mode spans at least one or more respiratory cycles; provide the therapy mode during a therapy session based on the received treatment set point and a comfort feature, wherein the comfort feature is added, deleted, or changed automatically during a therapy session without user intervention, wherein activation of the comfort feature results in a reduction of a pressure of the pressurized flow of gas being implemented in place of the received treatment set point in at least one phase of respiration, wherein activation of the comfort feature is based on one or more of time spent in the therapy mode, and/or time elapsed since activation of the pressure support system; and control the operation of the pressure generating system for at least one complete respiratory cycle responsive to the comfort feature being activated. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

28. 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; and a controller operatively coupled to the pressure generating system, wherein the controller is configured to; receive a treatment set point from an input source in accordance with a therapy mode, wherein the therapy mode spans at least one or more respiratory cycles; provide the therapy mode during a therapy session based on the treatment set point and an expiratory pressure relief, wherein the expiratory pressure relief is added, deleted, or changed automatically during a therapy session without user intervention, wherein activation of the expiratory pressure relief results in a reduction of a pressure of the pressurized flow of gas being implemented in place of the received treatment set point in at least one phase of respiration, wherein activation of the expiratory pressure relief is based on one or more of ambient humidity and/or altitude associated with the pressure support system; and control the operation of the pressure generating system for at least one complete respiratory cycle responsive to the expiratory pressure relief being activated. - View Dependent Claims (29, 30, 31, 32, 33, 34)
