Abstract
A respiration and heart rate monitoring apparatus includes a mechanical-electric apparatus for detecting chest movements and electrodes for detecting electric impulses associated with heartbeat. A highly sensitive detector includes a transducer crystal mounted in bridge-like configuration on pair of spaced piers connected by at least one flexible beam member. The transducer crystal and electrodes may be connected to circuitry for producing indications of respiration and heart rate. The circuitry blocks detection of chest motion substantially coincident with the impulses associated with heartbeat to inhibit erroneous indications of respiration caused by chest motion due to heartbeat. The circuitry also may block small, single polarity signals to inhibit erroneous indications of respiration caused by muscle noise.
