The Fingertip Pulse Oximeter fits all finger sizes from kids above four years old to adults as it measures the level of oxygen in the blood and reads the pulse rate in just eight to ten seconds. It is crucial to use the device in a stationary position and not while in motion for precise readings. While the AccuMed Fingertip Pulse Oximeter is handy for detecting vital signs, it is not intended for medical use but rather for situations where you need to know your oxygen level before and after your workout or sports such as running, hiking or cycling, or while traveling in an aircraft. Custom Logo Available. Price for over 2000 pcs is for sea shipment.
