While pulse oximeters became more apparent during the COVID-19 pandemic, this handheld device has always been popular in the medical, aviation, and sports community. Patients use them to track their asthma, chronic obstructive pulmonary diseases, and other lung conditions. Besides hospital and medical facilities, now pulse oximeters have been a staple in a regular households. One can simply put their finger in the device to check their blood oxygen level, pulse rate, etc. They are also used by pilots or endurance athletes who work or train at high altitudes.
What are Pulse Oximeters?
A pulse oximeter is an electronic device usually attached to a person’s fingers, wrist, ears, toes, foot, or nose to measure the level of oxygen in their red blood cells. The device offers instant results without the users giving a blood sample. It helps doctors determine whether a person requires supplement oxygen, ventilators support, or any airway pressure machine.
There are two types of pulse oximeters available in the market- Prescription pulse oximeters and OTC pulse oximeters.
The prescription pulse oximeters are FDA-approved devices that receive 501(K) clearance due to their accuracy and reliability. Meanwhile, the FDA has not reviewed an over-the-counter (OTC) pulse oximeter. One can buy them from a drugstore. Although they offer accurate results, unlike their FDA-approved counterparts, one cannot trust the results entirely.
In this article, we have selected the top 7 FDA-approved pulse oximeters of 2022 based on their accuracy, type, technical features, and price.
