Abstract: A device (102) 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 (102) 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.

Abstract: A detection appliance and a method detect and evaluate a measuring signal that is indicative of breathing of a sleeping person, in connection with the observation of sleep-related breathing disorders. Instruments also detect signals that are indicative of breathing of a patient. The aim provides solutions that enable a reliable examination in terms of occurrence of sleep-related sleeping disorders, in the usual surroundings of the person concerned. In a first form, a mobile detection appliance is provided with a sensor device for detecting a nasal flow signal indicative of a nasal respiratory gas flow, and/or a respiratory flow signal indicative of an oral respiratory gas flow, in addition to an electronic data processing unit comprising a memory device and processing the signals indicative of temporal course of the nasal and oral respiration. The data processing device is configured to store data indicative of temporal course of the respiratory flow signals.

Abstract: A patient interface is configured to deliver a flow of pressurized breathable gas to a patient's airways. The patient interface includes a central portion with an opening configured to deliver the pressurized breathable gas to the patient's nares. A first stabilizing portion extends from the central portion and is structured to engage an outer side of a respective one of the patient's nostrils. A second stabilizing portion is opposite the first stabilizing portion and extends from the central portion. In addition, the second stabilizing surface is structured to engage an outer side of a respective one of the patient's nostrils. The central portion, the first stabilizing portion and the second stabilizing portion cooperate to form a U-shape configured to cradle the patient's nose so that the tip of the patient's nose remains exposed when the patient interface is mounted on the patient's face.
