A HOME-BASED HELIOX SYSTEM WITH CARBON DIOXIDE REMOVAL

摘要

A closed-circuit heliox delivery system and methods for alleviating symptoms of COPD and related disorders are provided. The system is self-monitoring and can be used outside of a hospital environment. The system contains a gas supply fluidly connected to a breathing circuit. The breathing circuit contains an upper airway device, such as a mask. The system contains a sensor(s) and controller. The sensors measure parameters in the system, the ambient environment, or related to the physiological state of the user. The controller can adjust the system to maintain parameters within the device, i.e. pressure, temperature, humidity, within predetermined ranges. The controller can adjust the system to maintain a target physiological state of the user, i.e. target blood oxygen levels or Work of Breathing (WOB).

主权项

1. A closed-circuit heliox delivery system comprising:
a breathing circuit; a first sensor, the first sensor being operatively coupled to the breathing circuit; and a controller in electrical communication with the breathing circuit, wherein the controller is configured to receive input from the sensor and control operation of the breathing circuit in response to the received sensor input.
