ResHealth™

ResHealth™

The ResHealth™ system is a miniature, non-intrusive, multi-parameter respiratory breathing activity monitor that uses minimally invasive fluorescence lifetime fiber-optic sensors for the real time measurement of oxygen, carbon dioxide, moisture, and toxic chemical gases, with built-in all optical temperature and pressure sensing compensation. The ResHealth™ system is lightweight, compact, battery-powered, and includes wireless communication suitable for the remote alarm warning of respiratory disorder applications such as point-of-care sleep apnea occurrences in infants, children, and adults. It is also suitable for other respiratory monitoring applications for military and government personnel such as pilots, divers, and astronauts.
