  • Publication number: 20190262560
    Abstract: The present disclosure provides for an improved method of determining a water out condition in a humidified gases supply apparatus. The method includes a two-step process including a primary determination of a water out condition and a secondary determination of a water out condition. This primary determination is made during observation of the normal operation of the apparatus. During the secondary determination the method takes temporary control over the humidifying part of the apparatus. The secondary determination confirms or contradicts the primary determination.

  • Publication number: 20160228671
    Abstract: A humidification system can include a heater base, a chamber, and a breathing circuit. The heater base includes a heater plate positioned in a recessed region, and a heat conductive portion of the chamber is configured to contact the heater plate. The heater base includes a guard configured to control movement of the chamber into and out of the recessed region. The guard includes an anti-racking mechanism. The chamber includes an inlet port, an outlet port. A downward extension extends into the chamber from the inlet port, and a baffle is disposed at a lower end of the downward extension. A component of the breathing circuit can include a conduit hanging end cap for shipping and storage. The end cap can include a hanging component to allow the breathing circuit component to be hung from a medical stand. The system can detect when breathing circuits are connected in reverse.
