RESPIRATION OR RESPIRATION AND ELECTROCARDIOGRAPHIC MONITOR

摘要

Monitor (10) includes a patient unit (14) having an input circuit (22) applying a carrier signal from generator (18) through isolator (20) and signal receiving circuitry for demodulating the respiration signal (26-38) and for demodulating the electrocardiographic signal (70-75) and an analysis unit (16) including circuitry for the respiration signal (40-54, 58-64) and for the electrocardiographic signal (76-101) under control of a microprocessor (56). The respiration circuitry (26-38, 40-54, 58-64) may be employed by itself or with the electrocardiographic circuitry (70-101).
