Abstract
Apparatus for monitoring respiration and heartbeat and for processing electrical signals representative thereof, including circuits for developing a phase-shifted and amplitude-offset respiration signal for comparison with an original respiration signal for compensating for signal drift, and circuits for logically combining signals representative of the presence of respiration and heartbeat for eliminating certain false indications which may occur when only heartbeat exists.
