A method and apparatus for monitoring a subject to detect the occurrence of apnea, wherein the respiration rate and amplitude of the subject is detected by a plurality of electrodes for a predetermined initial time interval of a plurality of breath to produce a measure of the average respiration volume of the subject, the latter measurement is stored, and is compared with the detected respiration rate and amplitude of the subject during subsequent time intervals. A signal is generated whenever a detected average volume falls below the reference average volume by a predetermined percentage.
