    摘要： Method and apparatus for the treatment of cardiac failure, Cheyne-Stokes breathing or central sleep apnea are disclosed. A subject is provided with ventilatory support, for example positive pressure ventilatory support using a blower and mask. Respiratory airflow is determined. From the respiratory airflow are derived a measure of instantaneous ventilation (for example half the absolute value of the respiratory airflow) and a measure of longterm average ventilation (for example the instantaneous ventilation low pass filtered with a 100 second time constant). A target ventilation is taken as 95 % of the longterm average ventilation. The instantaneous ventilation is fed as the input signal to a clipped integral controller, with the target ventilation as the reference signal. The output of the controller determines the degree of ventilatory support. Clipping is typically to between half and double the degree of support that would do all the respiratory work. A third measure of ventilation, for example instantaneous ventilation low pass filtered with a time constant of 5 seconds, is calculated. Ventilatory support is in phase with the subject's respiratory airflow to the fuzzy extent that this ventilation is above target, and at a preset rate conversely.

    摘要： Apparatus for determining patency of the airway of a patient comprises:
    means for measuring respiratory air flow from the patient to derive an air flow signal; and
    a processor for analyzing said air flow signal to detect the presence of a cardiogenic air flow component, and determining whether the airway is patent depending upon the presence of a cardiogenic air flow component.

    摘要翻译： 公开了一种用于控制CPAP管理的装置，其中涡轮机（34）经由与面罩（30）连接的管（32）向患者气道的入口提供加压空气。 伺服控制器（40）响应于来自微控制器（62）的控制信号来控制电动机（38）并由此控制由涡轮机（34）输送的压力。 微控制器（62）确定是否发生呼吸暂停，如果是，则确定患者的气道是否是专利的，如果不是，则导致治疗压力的增加。 如果没有发生呼吸暂停，则微控制器（62）确定局部阻塞的存在和大小。 如果有部分梗阻，治疗压力会增加，如果没有部分阻塞，要减少。
