Abstract
A device () provides respiratory treatment for SDB (including mild OSA) and other respiratory conditions. A flow generator warms and humidifies gas at controlled flow levels. For example, the device () delivers breathable gas to the upper airway at flow rates of about 10-35 Liters/minute. Levels of flow rate, temperature and/or humidification of the device may be automatically adjusted in response to the detection of SDB events. The device may also automatically deliver adjustments of any of the levels in accordance with detected phases of respiratory cycles. In some embodiments, the device automatically delivers distinct levels to either of the nares based on independent control of flow to each nare. A warm-up procedure controls temperature and humidity at a desired target during a ramp-up of flow to the set therapy level. A cool-down procedure controls temperature above the dewpoint to avoid condensation internal to the device and patient interface.
