Nature Spirit Pulse Oximeter Pulse Rate Oxygen Level

* The NatureSpirit Fingertip Pulse Oximeter Rechargeable with LED Display is a portable pulse oximeter that is used to measure blood oxygen saturation value and pulse rate. This finger pulse oximeter has the potential todetect even small changes in how efficiently oxygen is being carried to the extremities furthest from the heart, including the legs and arms, to get a better sense of how blood is being pumped through the body.* In addition to tracking blood flow, this rechargeable pulse oximeter functions as a finger heart rate monitor, which can be especially helpful with conditions that can affect blood oxygen levels, including lung cancer, COPD, asthma, pneumonia, anemia, heart attack and congenital heart defects.* The NatureSpirit Fingertip Pulse Oximeter is very easy to use and features a rechargeable battery, a bright red LED display in a small package that makes measuring blood oxygen levels easy. The small clip-like device is placed on a finger while small beams of light pass through the blood in the finger, measuring the amount of oxygen. This painless process accomplishes this by measuring changes of light absorption in oxygenated or deoxygenated blood.
