Abstract
A patient monitor sheet device of simplified construction permits the accurate measurement of respiration, heart beat, and body position with a minimum of intrusion on the subject. Sensors are located in a bed sheet with which a subject comes in contact. One sensor produces a signal corresponding to respiratory induced, pulmonary motion, and myocardial pumping sounds. A second sensor produces a signal corresponding to changes in body position. A processor amplifies and filters the induced signals resulting in resolved output highly correlated to respiration rate, heart beat rate, and changes in body position.
