Abstract: The invention concerns an apparatus for delivering a gas mixture to the nasal airways of a spontaneously breathing child, the apparatus comprises a soother (11), a body (1) forming a mixing chamber attached to the soother and adapted for positioning over the nostrils of the child, at least one gas delivering hose (2) attached to the body forming the mixing chamber for supplying gas to the mixing chamber, wherein the mixing chamber has access to the surrounding air and is adapted for mixing the supplied gas with the surrounding air in order to provide a gas mixture for nasal inhalation, and wherein the body forming the mixing chamber comprises an edge portion (8) with at least one non-contact section, which is adapted for having no contact with the child when the apparatus is in use thereby providing access from the surrounding air to the mixing chamber.

Abstract: A device for determining one or more respiratory parameters relating to an individual is disclosed, as well as a method for determining one or more respiratory parameters by means of the device, wherein the individual is suffering from hypoxemia or is at risk of hypoxemia. However, the method and the device may also be applied to healthy individual e.g. for testing of medicaments. The device is controlled by a computer equipped with suitable software and includes functionality for on-line continuous data collection, automatic assessment of the timing of measurements, automatic assessment of the next target (oxygen saturation of arterial blood (SpO2)), automatic assessment of the appropriate fraction of oxygen in inspired gas (FIO2) settings to achieve the target SpO2, automatic control of the FIO2, on-line parameter estimation, and automatic assessment of the number of measurememts requied.
