Abstract
The invention determines the heart rate and respiration rate of a patient through the patient's extremities. Heart rate and respiration rate are determined via an energy spectrum, periodogram or histogram using a time series analysis. A patient can stand near the device and lean on it, or stand on a piezoelectric pad. A microcomputer provides calculations to determine heart and respiratory rates using signal processing and time series analysis of data.
