Abstract: An exchanger conduit permits temperature and/or humidity conditioning of a gas for a patient respiratory interface. In an example embodiment, a conduit has a first channel and a second channel where the first channel is configured to conduct an inspiratory gas and the second channel configured to conduct an expiratory gas. An exchanger is positioned along the first channel and the second channel to separate the first channel and the second channel. The exchanger is configured to transfer a component (e.g., temperature or humidity) of the gas of the second channel to the gas of the first channel. In some embodiments, an optional flow resistor may be implemented to permit venting at pressures above atmospheric pressure so as to allow pressure stenting of a patient respiratory system without a substantial direct flow from a flow generator of respiratory treatment apparatus to the patient during patient expiration.

Abstract: A system for therapy may include a mask (200) for a patient having a frame, cushion, forehead support and a light (100). The mask is connectable to a respiratory treatment apparatus, such as a flow generator, to receive breathable gas for a respiratory therapy. The light may also be connected to the power system and/or control system of the apparatus. A light may also be included in a module, such as a docking station, for a respiratory treatment apparatus. The lights may be controlled by one or more processors, and may be responsive to detected conditions, to assist with therapy. For example, the light may be turned on at a predetermined time or may be synchronized with the patient's sleep state, to assist in waking up the patient or re-setting the patient's circadian rhythm. Other components, such as sound and aroma generators of the system, may also be controlled for such therapies.
