Adenosine triphosphate (ATP) is the biochemical way to store and use energy. F or your muscles -- in fact, for every cell in your body -- the source of energy that keeps everything going is called ATP.
An approximate blood oxygen level can also be estimated using a pulse oximeter â a small device that clips on your finger. Though the pulse oximeter actually measures the saturation of oxygen in your blood, the results are often used as an estimate of blood oxygen levels.Normal pulse oximeter readings range from 95 to 100 percent, under most circumstances. Values under 90 percent are considered low.1  Causes.n approximate blood oxygen level can also be estimated using a pulse oximeter â a small device that clips on your finger.

A normal newborn pulse is between 120 and 180 beats per minute. A pulse of less than 100 beats per minute generally signifies low blood oxygen levels.reatment. A low pulse rate is more medically significant than a high pulse rate in a newborn, according to the New York State Department of Health. A low pulse requires treatment with chest compressions and assisted ventilation. Intubation and medication may be necessary to raise the pulse rate to normal.
