Abstract: A humidifier includes a tub configured to contain a supply of water and a heater including a first polymer film having an electrically conductive circuit provided upon a surface. The first polymer film is electrically insulating and the tub is formed of molded resin and the heater is molded at least partially within the resin. A respiratory apparatus for delivering a flow of breathable gas to a patient includes the humidifier. A method of humidifying a flow of pressurized breathable gas includes passing the flow of pressurized breathable gas over a supply of water contained in a tub. The tub is formed of molded resin and a heater including a first polymer film having an electrically conductive circuit on a first surface is molded at least partially within the resin.

Abstract: Methods and apparatus are disclosed for determining the occurrence of a closed or open apnea. Respiratory air flow from a patient is measured to give an air flow signal. The determination of an apnea is performed by applying an oscillatory pressure waveform of known frequency to a patient's airway, calculating a complex quantity representing a patient admittance (12) and comparing its value with ranges (14,16) indicative of open or closed apneas. The method distinguishes open from closed apneas even when the model used to calculate admittance is not based on details of the respiratory apparatus. In addition the patient admittance may be compared with admittance during normal breathing to avoid having to characterize the airway.
