The SM-110 is a best selling finger pulse oximeter, which has over 5,000 reviews on Amazon.com. Like most lower priced oximeters, this device is made in China. It is branded and marketed by Santamedical for resale in the United States. Owners notice that the “SM-110” lettering applied on the case tends to wear off quickly.
Though it is sold by a company with “medical” in their name, the SM 110 pulse oximeter is designed for sports and is not approved by the FDA for medical use. Even so, many reviews of this oximeter are from registered nurses, emergency medical technicians and respiratory therapists, who have purchased it to use in their work. While it is officially intended for pilots in un-pressurized aircraft, skiers, mountain climbers and other sports enthusiasts, most people use it to monitor their health. Patients with a respiratory illness and those on oxygen therapy like being able to easily check their blood oxygen level at home.
