A flow generator is adapted to be connected to the patient interface and to be secured by a portion of the patient's body. The flow generator includes a blower (50) adapted to provide pressurised breathable gas to a patient through the patient interface. The blower is adapted to be at least partially vibrationally isolated from the patient's body by at least one dampening system (49) or device. The dampening device or system is adapted to reduce the amount of transmitted vibration received by the patient. A PAP system includes a patient interface including sealing arrangement (30) adapted to form a seal with the patient's nose and/or mouth and headgear (40) to support the sealing arrangement in position on the patient's head. A blower is structured to generate a supply of pressurized air. The blower is supported by the patient interface on the patient's head and in communication with the patient interface. The headgear forms one or more ducts (42) to communicate pressurized air from the blower to a breathing cavity defined by the sealing arrangement.

摘要： An over-pressure control device prevents over-pressure conditions during the delivery of pressure treatment therapy to a patient with a respiratory treatment apparatus. The device may prevent delivered pressure from exceeding a first maximum pressure threshold. The device may also prevent the delivered pressure from exceeding a second maximum pressure threshold when the delivered pressure exceeds another pressure threshold for a period of time. In some embodiments, the second maximum pressure threshold may be lower than the first maximum pressure threshold. In an example embodiment, a set of comparators are configured to compare pressure with a maximum pressure threshold and to control a reduction in the pressure if the pressure exceeds the maximum pressure threshold. The set may also be configured to compare the pressure with a pressure threshold and to control reduction in the maximum pressure threshold if the pressure exceeds the pressure threshold for a period of time.

摘要： A flexible tape heater (110) in a patient conduit (112) may be used to heat the flow of gas in the patient conduit (112) that is delivered to the patient mask (116). The thin, flat and extended nature of the flexible tape heater (110) may enhance heat transfer with the gas flow whilst also providing low impedance to the gas flow. Heating of the gas may facilitate the desired temperature and humidity to be reached for the gas delivered to the patient by the respiratory apparatus. The flexible tape heater (110) may be placed in the patient conduit (112) such that the flexible tape heater (110) is twisted or bent about one or more of the flexible tape heater's (110) three axes. Additionally these configurations may be used to enhance the turbulent mixing of the water vapour produced in the humidification chamber (114) with the gas flow.

摘要： 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.
