The Fingertip Pulse Oximeter is a small, portable pulse oximeter that takes measurements from the fingers. The nicest part about a finger pulse oximeter is that we can take it with us everywhere and check our pulse rate whenever we want with a single touch. It is a non-invasive method for determining arterial blood oxygen saturation (SPO2), heart rate, and perfusion index (based on the model). It's usually used in conjunction with high-flow equipment, an oxygen concentrator, or an oxygen cylinder. We offer Fingertip Pulse Oximeter at very attractive prices to bulk buyers.
