Abstract
A method for detecting apnea by sampling a voltage waveform representative of respiration at regular intervals and calculating the instantaneous voltage differences at alternate sample points, and comparing the magnitude of each difference voltage so calculated against a "threshold" value determined to be the minimum value consistent with normal respiration activity.
