摘要：
Methods for detecting a patient disconnecting from a continuous positive airway pressure (CPAP) therapy device are disclosed. A cyclical pressure difference signal is derived based upon measurements from a patient interface pressure sensor and from a source pressure sensor. The pressure difference signal is integrated to generate a resultant integral signal for each respiratory cycle, which is comprised of at least one inspiratory phase and at least one expiratory phase as represented by the corresponding portions of the pressure difference signal. A pressure source of the CPAP therapy device is deactivated in response to a disconnect condition being evaluated from the integral signal. In one embodiment, the disconnect condition is the integral signal exceeding a predefined disconnect threshold. In other, it is a slope value corresponding to a rate of increase of the integral signal exceeding a predefined threshold for a predefined duration.
摘要（中）：
公开了用于检测患者与连续气道正压通气（CPAP）治疗装置断开连接的方法。 基于来自患者界面压力传感器和源压力传感器的测量值导出循环压差信号。 压差信号被积分以产生每个呼吸周期的合成积分信号，其由至少一个吸气相和至少一个呼气相组成，如由压力差信号的对应部分所表示的。 CPAP治疗装置的压力源响应于从积分信号评估的断开条件而被去激活。 在一个实施例中，断开条件是超过预定义的断开阈值的积分信号。 另一方面，与预定的持续时间内的积分信号的增加率超过规定的阈值相对应的斜率值。
