Abstract
A respiration monitor is disclosed which includes a simplified pneumatic breath detector, a pressure sensor connected with the detector, and an active low pass filter for filtering the output of the monitor to reduce signals not indicative of respiration, such as movement of and/or impacts upon the detector. The monitor may be linked with a transmitter for remote subject monitoring, and the entire monitor may be configured to be unobtrusively worn by the subject.
