Abstract: A stretchable harness-like apparatus enables physiological parameters of a patient to be measured while he or she is ambulatory or stationary. The invention has a chest band, an optional shoulder band(s), and an optional abdominal band that can house respiration, pulse and ECG sensors. The shoulder band(s) are attached to the chest band and all of the bands are worn on the body under a low tension. The apparatus is typically used in conjunction with on-body monitoring electronics and radio-linked to remote alerting modules or it can be hard-wired to on-body or remote monitoring and alerting equipment. The compliant nature of the device allows for accurate monitoring without sacrificing patient mobility or comfort.
