Abstract :
The body respiratory rate (RR) is the optional parameters of vital signal, and it is one of the monitoring
indicators of physiological distress. The paper presents a test method of body respiratory rate by using the
status sensors and infrared imaging sensors. The method of the Kalman filter and zero crossing test are
applied in the RR test, the measurement and simulation results show its feasibility. And they are compared
with testing by commercial pressure sensors module, the results show the effective of methods
