As we learn more about COVID-19, recommendations and guidance are updated frequently. Please check back often.
The oximeter works correctly. The oximeter is supplied with a finger probe. For some oximeters ear probes are also available and are also described here. Probes are carefully designed so that they can shine light through the finger and detect it on the other side.

How does COVID-19 lower a person’s oxygen levels?
Many people with COVID-19 have low levels of oxygen in their blood, even when they feel well. Low oxygen levels can be an early warning sign that medical care is needed.
What is a pulse oximeter?
A pulse oximeter measures how much oxygen is in someone’s blood. It is a small device that clips onto a finger, or another part of the body. They are used often in hospitals and clinics and can be bought to use at home.
Many people consider oxygen level an important sign of how well a body is working, just like a person’s blood pressure or body temperature. People who have a lung or heart condition may use a pulse oximeter at home to check how they are doing, as directed by their health care provider. People can buy pulse oximeters without a prescription at some pharmacies and stores.
Can a pulse oximeter tell if someone has COVID-19 or how well they are doing if they have it?
We do not recommend using a pulse oximeter as a way to tell if someone has COVID-19. Get tested if you have signs of COVID-19 or if you have been close to someone who has it.
If someone has COVID-19, a pulse oximeter may help them keep watch over their health and to know if they need medical care. However, while a pulse oximeter may help someone feel like they have some control over their health, it does not tell the whole story. Oxygen level measured by a pulse oximeter is not the only way to know how sick someone is. Some people may feel very sick and have good oxygen levels, and some may feel OK, but have poor oxygen levels.
Pulse oximetry results may not be as accurate for people with darker skin. Their oxygen levels are sometimes reported as higher than they really are. People who check their own oxygen levels, or those who check it for them, should keep this in mind when looking at results.

Oxygen levels may be low if someone feels short of breath, is breathing faster than usual, or feels too sick to do their usual daily activities, even if a pulse oximeter says their oxygen levels are normal. Call a doctor or another health care provider right away if you have these symptoms.
What are normal readings?
A normal level of oxygen is usually 95% or higher. Some people with chronic lung disease or sleep apnea can have normal levels around 90%. The “SpO2” reading on a pulse oximeter shows the percentage of oxygen in someone’s blood.
If your home SpO2 reading is lower than 95%, call your health care provider.
Lung Procedures, Tests & Treatments
If you have a symptom of shortness of breath or a known lung or heart condition, your doctor may recommend use of a pulse oximeter. The pulse oximeter, or Pulse Ox,is an electronic device that measures the saturation of oxygen carried in your red blood cells. Pulse oximeters can be attached to your fingers, forehead, nose, foot, ears or toes. The device may then be reused or disposed of. If using this in a home setting, you should ask your healthcare provider before disposing of a pulse ox device, as it can be expensive and is reusable.
In February 2021, the Food and Drug Administration issued an alert on limitations of pulse oximeters. If you have poor circulation, dark skin pigmentation, thick skin, currently use tobacco, your skin temperature is cool, or you are wearing dark fingernail polish, long, artificial nails or if your fingers are not clean, the pulse oximeter may give inaccurate or inconsistent readings. This is why the numbers from a pulse oximeter should not be used in isolation to determine your state of health. It is important to share readings that are abnormal or inconsistent with your healthcare provider.

Oximeter Usefulness
What to Expect?
If working accurately, you can expect a simple, quick and safe measure of the oxygen saturation level in your body. The probe will be positioned and within a few seconds, the oximeter will provide a readout of your heart rate and your oxygen saturation level, as in the picture above. There are no needles and no pain involved in oximetry measurement. Some hospitals also use disposable tape probes that wrap around your finger, nose or toe.
The pulse oximeter uses a cold light source that shines a light through the fingertip, making the tip appear to be red. By analyzing the light from the light source that passes through the finger, the device is able to determine the percentage of oxygen in the red blood cell.
Understanding the Results
The pulse oximeter observes a rapid measurement of oxygen saturation level in your body without using needles or taking a blood sample. The measured amount shown on the screen reflects the saturation of your red blood cells with oxygen. This number gives your doctors and nurses an idea of what your treatment will be. The oxygen level may also help to determine if you need to receive supplemental oxygen. This saturation number (a good number would be over 90-92%) differs from a value called the pO2 (a good number would be over 60-65) which is measured by obtaining blood from an artery. Your doctor can clarify the significance of your value related to your particular situation.
