Note: Fingernail polish and acrylic nails may result in inaccurate readings. In this case, turn your finger 90 degrees so the light shines through the sides of your finger and not through the nail.

A pulse oximeter is a handheld, clip-like electronic device designed to measure the oxygen level of your blood, and your heart rate. Although sometimes considered a heart rate monitor, it is somewhat different.
A pulse oximeter works by shining small beams of light into the skin and measuring the amount that passes through the blood. The sensor calculates the level of oxygen available since oxygenated and deoxygenated blood absorbs light to different degrees. The process is non-invasive and get you results quickly.
One of the many essential functions of blood is absorbing oxygen from the air breathed in through the lungs, and carrying it to cells via the blood vessels. A pulse oximeter measures the oxygen saturation levels in your blood. It is a way to check how well the heart is pumping oxygen throughout your body. It also measures your heart rate.
To get the most accurate reading, follow the directions on the package closely. There are two numbers on the screen: The oxygen saturation percentage is above, and the heart rate shown below as beats-per-minute. A saturation level of 95-100% is considered normal for typical healthy individuals.
Oxygen level readings by a pulse oximeter are typically with a margin of 2% over or under what the number would be when measured by arterial gas saturation testing method. For example, if the reading is 93% on the pulse oximeter, the actual oxygen level might be somewhere between 91 to 95%. Keep your hands still during the measurement. Body motion or temperature can impact accuracy. Readings may be less accurate if a person is wearing nail polish or artificial nails, and places the sensor over the nail. Accuracy can also be affected by cold hands or poor circulation.
