A pulse oximeter is a small medical device that is used to measure the oxygen saturation (SpO2) and pulse rate in the blood. It is a non-invasive and painless tool that is often used to monitor oxygen levels in patients with respiratory or cardiovascular conditions. Here are some frequently asked questions about pulse oximeters:
How does a pulse oximeter work?A pulse oximeter works by shining two wavelengths of light (usually red and infrared) through a finger or earlobe. The device then measures the amount of light that is absorbed by the blood and calculates the oxygen saturation and pulse rate.
​​​​Who can benefit from using a pulse oximeter?
Pulse oximeters are commonly used by people with respiratory or cardiovascular conditions, such as chronic obstructive pulmonary disease (COPD), asthma, heart failure, and sleep apnea. They may also be used by athletes to monitor their oxygen levels during exercise.
How accurate are pulse oximeters?
Pulse oximeters are generally considered to be accurate when used properly. However, factors such as nail polish, skin pigment, and movement can affect the accuracy of the readings.
Can pulse oximeters be used to diagnose COVID-19?
Pulse oximeters may be used as a tool to monitor the oxygen levels of patients with COVID-19. However, they should not be used as a diagnostic tool, and a healthcare professional should be consulted for a definitive diagnosis.
How often should I use a pulse oximeter?
The frequency of pulse oximeter use depends on the individual's medical condition and the advice of their healthcare provider. People with chronic conditions may need to use a pulse oximeter daily or as recommended by their healthcare provider.
Are pulse oximeters covered by insurance?
Pulse oximeters may be covered by insurance if they are deemed medically necessary by a healthcare provider. However, coverage may vary depending on the insurance plan.
It's important to keep in mind that a pulse oximeter is a screening tool and not a replacement for medical advice from a healthcare professional. If you have concerns about your oxygen levels or other symptoms, it's important to contact your healthcare provider.
