A normal pulse oximetry reading ranges from 95 percent to 100 percent, according to Mayo Clinic. Anything below 90 percent is considered a low reading.Know More
Pulse oximeters read the percentage of oxygen in a person's blood, states Meditech. They also track a person's heart rate. Pulse oximeters were developed to help diagnose low blood oxygen, a condition called hypoxia. Sometimes the oximeter returns a false reading, either too high or too low. False readings can occur with increased patient movement, a low body temperature, anemia, in cases of shock and in cases of carbon monoxide poisoning. Nail polish can also affect the reading if the oximeter is used on a finger.
A normal blood oxygen saturation level ranges from 95 to 100 percent, according to the Mayo Clinic. Values under 90 percent are considered low. Oxygen saturation levels are measured using a pulse oximeter, a small device that clips onto the patient's finger.Full Answer >
In children, the normal pulse ox reading that measures the amount of oxygen in the blood is 96 to 98 percent, states AboutKidsHealth. Anything under 95 percent is abnormally low and may cause doctors to order additional testing, states Children's National Health System.Full Answer >
In most cases, a normal pulse oximeter reading ranges from 95 to 100 percent, reports Mayo Clinic. The pulse oximeter is a device that measures oxygen saturation.Full Answer >
The normal range of SaO2 is around 97 percent, although anything in the region of 95 to 100 percent is considered to be within the norm. When combined with PaO2 and CaO2 readings, this range gives a good indication of a patient's blood oxygen levels, and whether they are adequate. As a result, while SaO2 levels are important, they are only one part of the wider picture.Full Answer >
