AUTOMATIC HUMIDITY CONTROL IN A PRESSURE SUPPORT SYSTEM
First Claim
1. A method of automatically controlling a humidity of a gas stream of a pressure support system during use of the pressure support system by a user, comprising:
- receiving a first humidification level; and
controlling operation of a humidifier of the pressure support system based on the first humidification level and one or more parameters indicating the user'"'"'s actual demand for respiratory gas during a breath.

Abstract
A method of automatically controlling the humidity of a gas stream of a pressure support system (50) during use of the system is provided. The method includes receiving a first humidification level, and controlling operation of a humidifier (68) based on the first humidification level and at least one of: (i) one or more environmental parameters relating to environmental conditions around the pressure support system, (ii) one or more gas stream parameters relating to a gas stream output by the pressure support system to a patient circuit (56, 58), (iii) one or more respiratory demand parameters of a user of the pressure support system, and (iv) one or more operating parameters of the pressure support system that effect a flow rate that is generated by a pressure generating system (52, 60) of the pressure support system.

12. A pressure support system, comprising:
-
a pressure generating system structured to generate a pressurized gas stream; a humidifier structured to humidify the pressurized gas stream; a patient circuit operatively coupled to the humidifier; and a controllers operatively coupled to the pressure generating system and the humidifier, the controller being adapted to control a humidity of a humidified gas stream output by the humidifier by receiving a first humidification level, and controlling operation of the humidifier based on the first humidification level and one or more parameters indicating a user'"'"'s actual demand for respiratory gas during a breath - View Dependent Claims (13, 15, 16, 17, 18, 19, 21, 22, 24)
