The Florida-based company specializes in improving and expanding the use of conventional pulse oximetry by monitoring critical patient parameters and increasing the number of parameters that can be measured. Xhale's SMART medication adherence monitoring technology and propofol monitor are designed to provide a simple, highly-effective single-point-of-contact sensor that can reliably monitor critical parameters under challenging conditions for patients. In addition to these products, Xhale also developed the HyGreen hand hygiene monitoring and recording system, which was successfully commercialized and spun out as a separate company in 2010.
