Pulse oximetry is a noninvasive and painless test that measures your oxygen saturation level, or the oxygen levels in your blood. It can rapidly detect even small changes in how efficiently oxygen is being carried to the extremities furthest from the heart, including the legs and the arms.
The pulse oximeter is a small, clip-like device that attaches to a body part, like toes or an earlobe. It’s most commonly put on a finger, and it’s often used in a critical care setting like emergency rooms or hospitals. Some doctors, such as pulmonologists, may use it in office.

Monitoring Tip:
Normal arterial oxygen is approximately 75 to 100 millimeters of mercury (mm Hg). Values under 60 mm Hg usually indicate the need for supplemental oxygen. Normal pulse oximeter readings usually range from 95 to 100 percent. Values under 90 percent are considered low.
The purpose of pulse oximetry is to check how well your heart is pumping oxygen through your body.
It may be used to monitor the health of individuals with any type of condition that can affect blood oxygen levels, especially while they’re in the hospital. These conditions include:
- chronic obstructive pulmonary disease (COPD)
- asthma
- pneumonia
- lung cancer
- anemia
- heart attack or heart failure
- congenital heart defects
There are a number of different common use cases for pulse oximetry, including:
- to assess how well a new lung medication is working
- to evaluate whether someone needs help breathing
- to evaluate how helpful a ventilator is
- to monitor oxygen levels during or after surgical procedures that require sedation
- to determine how effective supplemental oxygen therapy is, especially when treatment is new
- to assess someone’s ability to tolerate increased physical activity
- to evaluate whether someone momentarily stops breathing while sleeping — like in cases of sleep apnea — during a sleep study
How to use it:
Step 1
Turn on the pulse oximeter by firmly pressing the power button. The screen should light up almost instantly.
Step 2
Place the sensor — the part that opens and closes like a clothespin — on any finger, with the sensor screen above the fingernail. If the sensor doesn’t have a screen, run the cable along the back of the finger or hand. Don’t use the thumb because readings are less reliable than finger readings.
Step 3
Wait quietly while the pulse oximeter acquires a signal. This may take 10 seconds or more, depending on the device and the conditions. Excessive movement during measurement can decrease the accuracy of the result or may cause an error message.
Step 4
Look at the display to see the heart rate, usually indicated with a heart or pulsing light. The percent of oxygen saturation is typically indicated by the symbol “SpO2.” Many devices also have a pulse tone that beeps in time with the heart rate.
Step 5
Leave the sensor on for continuous monitoring. The sensor can become uncomfortable or cause pressure sores if left on the finger too long. Check and/or move the sensor at least every two to four hours. If only a single measurement is required, remove the sensor and press the power button to turn off the device.
Tips:
- To ensure proper function, read the manual for your specific pulse oximeter.
- Remove nail polish, especially dark colors, before placing the sensor on the finger.
- Place the sensor on the finger before turning on the pulse oximeter for a faster result.
- Pulse oximeters are less accurate if there is poor blood flow to the finger. This may occur if the person is cold, has very low blood pressure or is having a heart attack.
- Carbon monoxide — due to smoke inhalation, carbon monoxide poisoning or heavy cigarette smoking — results in falsely high pulse oximeter readings.
- Altitude may result in lower percent oxygen saturation due to the lower oxygen pressure in the air, particularly if you have recently arrived.
Warning
A normal percent oxygen saturation reading is in the 95 to 100 percent range. In the event of a low oxygen saturation measurement, look for signs of respiratory distress. This includes shortness of breath, wheezing, difficulty breathing or a bluish discoloration of the face, lips or fingernails.
Seek medical attention right away if the respiratory distress is a new or uncomfortable symptom. if it’s getting worse or if the pulse oximeter measurement is below 90 percent.
