Our finger clip pulse oximeter products are approved by FDA\CE experts.
Why trust us?
Before the COVID-19 pandemic, the last time you saw a pulse oximeter was during an annual checkup or in the emergency room. But what is a pulse oximeter? When does someone need to use a pulse oximeter at home?
A pulse oximeter is a small clip-on device with a chip that uses photoelectric, non-invasive detection to quickly obtain blood oxygen levels and pulse rate (also known as heart rate). Your heart rate is the number of times your heart beats per minute, and it increases when you need more oxygen-rich blood to deliver nutrients and energy to your muscles and cells. Oxygen saturation is an important indicator of lung function.
A pulse oximeter measures the oxygen saturation of red blood cells, and we use it to measure how well a person’s lungs are working and how well they are absorbing oxygen from the air they breathe, says Fadi Youssef, PhD, MD, board certified Memorial Nursing Long Beach Medical in California Pulmonologists, internists and critical care specialists at the center. Therefore, pulse oximeters can help us understand whether and how much COVID-19 is affecting our lungs.
People with COVID-19 may experience increased heart rates due to fever or inflammation as the heart works harder to pump more blood to different parts of the body. In severe cases, the infection can spread to the lungs through the airways, making it difficult for blood to deliver oxygen to the lungs. The Centers for Disease Control advises people to seek medical help if they have significant symptoms such as “trouble breathing” and “persistent chest pain or tightness.” Depending on the severity of your condition, or if you are at higher risk for adverse outcomes due to advanced age or obesity, your doctor may recommend using a pulse oximeter to measure your vital signs at home.
Pulse oximeters are suitable for use outside of COVID-19. Dr. Yusuf said having a pulse oximeter in the home may be helpful for patients with lung disease or using a home oxygen concentrator to maintain healthy oxygen levels. Doctors give instructions on when and how to use and read a pulse oximeter, but Dr. Yusuf gave us what he considers a normal range for blood oxygen saturation.
“For most healthy people, healthy reading scores are probably above 94 percentile, but we don’t worry until the score is consistently below 90 percentile.”
Dr. Yusuf said not all pulse oximeters purchased online are legal. Pulse oximeters are FDA-approved medical devices, so you should check the FDA database to make sure the manufacturer and model have been tested and approved for accuracy.
Luckily, we’ve done all the work for you and compiled a list of the best pulse oximeters on the market that are also FDA-approved. If you have COVID-19 or another illness that affects your lungs and want to monitor your oxygen saturation levels at home, check out the pulse oximeters below.
