Zephyr Technology's Performance Status Monitor (PSM) offers visibility into the physical status of personnel deployed in the most challenging environments. Deployed over existing digital radio equipment, the PSM Responder offers a low hassle, cost effective way to help improve the safety of your team. The solution centers on the BioHarness, which monitors heart rate, breathing rate, skin temperature, posture, and activity. The Smart Fabric strap can be worn as a chest strap, or as a fully integrated shirt. PSM Responder's OmniSense Live Software presents a simple red-orange-green status in the patented BioGauge to maximize your team's ability and measure life anywhere.
