    摘要: A respiration monitor for use in an apnea monitor is disclosed in which a threshold value signal is automatically generated proportional to the average value of the monitored impedance of the subject during a base period selected by the operator. A comparator circuit operates to indicate respiration when the ratio between the threshold value signal and the impedance signal reaches a predetermined proportionality factor.
