1. A multi-channel ventilation monitor for real-time monitoring of multiple physilogical activities associated with respiration of a monitored subject, involving comparison of a plurality of discrete data signals indicative of each such activity, said monitor comprising, in combination: (a) a plurality of sensors for detection of discrete physiological activity indicative of breathing activity, each of said sensed physilogical activity being converted by a transducer to data signals which are characteristic of the sensed physiological activity; (b) a plurality of discrete information processing channels for processing of the physiological data signal from each sensor, each such physiological data signals being processed in a separate channel; (c) a signal processing means for each such channel for verifying the quality of each such signal; (d) means for dynamic adjustment of the gain and frequency response for each of the sensed physiological activity to reflect trends in the data signal for each such physilogical activity; (e) means for comparison of the wave form of each such signal to certain standards, including wave forms of a sensed physilogical activity which have been stored in a data base and wave forms of sensed physiological activity which are indicative of a trend in a sensed activity for the monitored subject; and (f) means for generation of an output signal to indicate abnormal physilogical activity associated with respiration.
