摘要： A controller or processor for a respiratory pressure treatment device determines an estimate of patient respiratory flow based on a measure of pressure associated with flow generated by a flow generator and a measure of frequency of the flow generator, such as a rotational velocity of a servo-controlled blower motor. The estimate can be made without data from a flow sensor. The measure of frequency may be converted to an expected pressure based on characteristics of the flow generator and subtracted from the measured pressure to determine the flow estimate. The flow estimate can be implemented in the provision of respiratory pressure treatment with the flow generator. For example, the flow estimate may be utilized to trigger expiratory pressure relief during a patient's expiration as detected with the estimated flow signal.

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.
