What is a Pulse Oximeter?

Pulse oximeters measure light absorption in the finger to noninvasively monitor oxygen saturation and pulse rate. Fingertip pulse oximeters are being increasingly used for general wellness and health applications including sports, fitness, relaxation management, and disease management such as: chronic obstructive pulmonary disease, asthma, and heart failure.

Challenges With Other Fingertip Pulse Oximeters

Multiple companies have introduced low-priced, battery-powered “fingertip” pulse oximeters to the consumer market. In some circumstances, these products may provide inaccurate measurements or no measurements at all. This often occurs when there is low blood flow to the finger (such as when the fingers are cold) or during hand movement (even with minimal motion such as shaking). In addition, many of the products on the market are of low quality and do not interface with smart phones to store, manage, and share data.
