    Abstract: Methods and apparatus for detecting apnoea that use ultrasonic sound waves are disclosed. The method consists of applying ultrasonic sound waves of varying frequency to a patient's airway and detecting their reflected sound waves. The sound waves are then analysed to determine whether there is a narrowing of the airway. In particular a transmitting ultrasonic transducer and receiving ultrasonic transducer are located on the interior surface of a mask and positioned so as to be directed towards the nares of the patient. A signal is emitted through the transmitting transducer and received at the receiving transducer. The received signal indicates a distance to a reflection or a distance to the narrowing of the upper respiratory tract. In this manner obstructions or narrowing of a patient's airway tract may be identified as reflections which appear at anatomically appropriate distances.

    Abstract: A user interface (22) with headgear (29) is disclosed where a flexible conduit (24) supplies gases to the patient interface and the conduit is connected to the headgear by a sliding connection or support portion (26). In one form headgear may include a transverse strap which the conduit is attached to. In other forms various sliding straps constrain the conduit such that forces on the conduit are transferred to the headgear not the interface. Interface vertical height and angular adjustment mechanisms are also disclosed.

    Abstract: A patient interface is described which is reduces the pressure of the mask on the users face. The patient interface has a sealing interface having an inner sealing member and an outer sealing member. The inner and outer sealing members are adapted to seal around the facial contours of a user providing a sealed fluid communication to the user's respiratory tract. The inner and outer sealing members are at least continuously in contact with each other around the portions where the sealing interface contacts the user's facial contours. The inner sealing member may be provided with cut outs to provide additional flexibility to particular areas, such as the nasal bridge, upper lip or cheek regions and may be provided with a contoured edge to better fit the facial contours of a user.

    Abstract: An infrared gas analyser. The analyser comprises a sample cell located in a gas flow, a source of infrared radiation of selected wavelengths which is propagated through the sample cell and an infrared detector which receives radiation which has passed through the cell, The radiation incident on the detector provides a measure of the concentration of selected substances in the gas flow due to one of the wavelengths being selected to be absorbed by the gas being measured. One preferred use is as a humidity sensor in a medical respiratory circuit where at least one selected wavelength is a wavelength strongly absorbed by water. Heating means am associated with the sample cell to vaporize any liquid water which may enter it and the cell is provided with internal baffles to reduce deposition or condensation of water on internal surfaces through which infrared radiation must pass. In one embodiment two selected wavelengths are derived from a single source with the second reference wavelength being a wavelength which is not significantly absorbed by the gas being measured and the source is switched between two power supplies to ensure the output of the detector is equal for the two wavelengths when the concentration of the measured gas is zero.In a second embodiment two single wavelength sources are used and their combined outputs passed through the sample cell.
