BREATH DETECTION WITH MOVEMENT COMPENSATION

An oxygen concentration system may comprise a pressure sensor, a movement sensor, and a controller configured to use one or more pressure signals obtained from the pressure sensor and a movement signal obtained from the movement sensor to determine when to release a bolus of oxygen enriched air. In...

Beschreibung
Zusammenfassung:	An oxygen concentration system may comprise a pressure sensor, a movement sensor, and a controller configured to use one or more pressure signals obtained from the pressure sensor and a movement signal obtained from the movement sensor to determine when to release a bolus of oxygen enriched air. In some implementations, the controller may adjust a trigger threshold based on an initial pressure signal obtained from the pressure sensor and the movement signal obtained from the movement sensor. In some implementations, the controller may adjust a pressure signal obtained from the pressure sensor based on the movement signal obtained from the movement sensor. In some implementations, the controller may detect a potential onset of inhalation from a pressure signal obtained from the pressure sensor and determine whether to verify the potential onset of inhalation based on the movement signal obtained from the movement sensor.
