Woodland Hills-based SPO Medical Inc. has launched its PulseOx 7500 a new wrist-mounted device that measures the vital signs of people experiencing sleep disorders. The FDA- and CE-approved device measures oxygen saturation and heart rate, which typically reflect conditions of sleep problems such as sleep apnea. A sensor is attached to the wearer’s finger, which then relays the data to a wrist watch-like device, where it is stored. The information can then be downloaded and sent to a physician for analysis.
