    Abstract: Disclosed is a humidifier for a respiratory apparatus for delivering a humidified flow of breathable gas to a patient. The humidifier includes a humidifier chamber configured to store a supply of water to humidify the flow of breathable gas. The humidifier chamber has a first heating element configured to heat the supply of water. The humidifier has a delivery hose with a first end configured for connection to an outlet of the humidifier and a second end configured for connection to a patient interface. A second heating element is configured to heat the humidified flow in the delivery hose. The humidifier includes at least one sensor to detect an absolute humidity of the humidified flow and generate signals indicative of the absolute humidity and a controller configured to receive the signals from the sensor and control the first heating element to provide a predetermined absolute humidity, a predetermined temperature, and/or a predetermined relative humidity to the flow of breathable gas. The controller is configured to determine a change in the rate of the flow of breathable gas and control the second heating element to adjust the predetermined temperature when the change in the flow rate exceeds a predetermined flow rate change.

    Abstract: A CPAP device includes a humidifier including humidifier tub having a heat conducting base plate; and a cradle to support the humidifier tub in an operative position. The cradle may also support a flow generator in operative relation to the humidifier tub. The cradle includes a heater plate in communication with the heat conducting base plate of the humidifier tub in use. The cradle further includes a retaining mechanism to retain the humidifier tub in the cradle, the retaining mechanism being structured to force the base plate into engagement with the heater plate. The humidifier and/or flow generator may include various features to manage inadvertent back-spill of water from the humidifier to the flow generator.
