What Is a Pulse Oximeter? 

A pulse oximeter is a painless and non-invasive way to monitor your oxygen levels or the oxygen saturation of your red blood cells as well as your pulse rate. Pulse oximeters measure how effective oxygen is at being delivered to your extremities (arms and legs) from your heart. Pulse oximeters also track your heart rate in beats per minute (BPM).

How Does a Pulse Oximeter Work? 

A pulse oximeter rests on your finger, ear lobe, nose, forehead, toe, or wrist to detect your blood oxygen levels. The reason these areas are used to determine your blood oxygen level is because they have higher vascular densities than other parts of the body.

A pulse oximeter works by attaching to most commonly your finger and using cold light wavelengths to shine through the site of application and measure how much oxygen is in your blood. The light passes through your fingernail, skin, tissue, and blood. When this occurs, the sensor is able to determine the amount of light that went through your finger, and thus, figuring out your blood’s oxygen saturation. By finding out your oxygen saturation, you can measure how your lungs are performing, which is useful in discovering illness. When you start to get sick, your oxygen levels will drop, indicating that it is time to see your doctor.

How to Use a Pulse Oximeter

To properly use a pulse oximeter, ensure it is positioned correctly and securely to make sure the right amount of light travels through your finger or place of application. Remove any nail polish as it might obscure the light’s ability to read your information. To get the most accurate reading, warm your fingers or toes before applying the pulse oximeter. Lastly, make sure you are sitting still. If you move around a lot while the pulse oximeter is reading, you will lower the effectiveness.

What Does a Pulse Oximeter Measure?

A pulse oximeter measures the oxygen saturation of your blood and how effective your heart is in supplying oxygen to the rest of your body. Pulse oximeters also determine how well your lungs are performing. Pulse oximeters measure your pulse rate, which is determined by the number of times your heart beats in a minute.

Pulse oximeters are useful to monitor health conditions such as:

  • COVID-19
  • Pneumonia
  • Chronic Obstructive Pulmonary Disease (COPD)
  • Asthma
  • Lung Cancer
  • Heart Health Conditions: Heart Attacks, Heart Defects, or Heart Failure

How to Read a Pulse Oximeter

To read a pulse oximeter, you will see two numbers. One is your blood oxygen saturation level, which is shown in units of SpO2. The other number is your heart beats per minute (BPM).

According to the World Health Organization (WHO), a healthy reading for a pulse oximeter is between 95% and 100%. If you have previous health concerns, your levels will typically be above or below 95. However, depending on your condition, you should talk with your doctor about the appropriate number for you. If your blood oxygen saturation is low, you may be experiencing breathing difficulties, a lung infection, blocked airways, or poor blood circulation.


An at-home pulse oximeter puts you in charge of your health by allowing you to monitor and measure your blood oxygen and pulse rate from the comfort of your home. The best pulse oximeter for you depends on the lifestyle factors that matter the most to you!
