Wrist-Mounted System for Extended Oximetry Monitoring

A new wrist-mounted oximetry system monitors vital signs of people experiencing sleep disorder symptoms, such as sleep apnea.

The PulseOx 7500, manufactured by SPO Medical (Woodland Hills, CA, USA), is used for extended monitoring of blood oxygen saturation and heart rate using reflectance pulse oximetry (RPO) technology. The compact, easy-to-use pulse oximetry system includes a ring sensor placed at the base of the finger to measure oxygen saturation and heart rate, connected to a watch-like, wrist-mounted monitor. The monitor collects and stores data over extended periods of time, including overnight while the wearer sleeps. The next morning, data can be downloaded for analysis via the sleep apnea reporting software and connecting cables that are supplied with each unit.

A key benefit of the system is that it reduces the cost of sleep apnea pre-screening. The PulseOx 7500 costs far less than traditional sleep-monitoring equipment and uses long-life batteries for extended periods of constant use, thereby reducing operational costs.

"We're proud to be launching our third portable monitoring device to capture life-saving and/or life-enhancing data within less than two years of introducing our first product,” said Michael Braunold, president and CEO of SPO Medical. "With the PulseOx 7500, we're offering family care and general practitioners, patients, and insurance companies a cost-effective product to pre-screen patients' vital signs related to sleep disorders in the comfort of the patient's home.”

Pulse oximetry is a non-invasive process used to measure blood oxygen saturation levels (SpO2) by monitoring the percentage of hemoglobin (Hb) that is saturated with oxygen, as well as measuring heart rate. The procedure has been used regularly in hospitals during the past twenty years and is established as an essential measurement in medical practice.
