What does an oximeter do?
A pulse oximeter is used to measure the amount of oxygen carried by your blood around your body. The oximeter tool is attached to your fingertip and uses two wavelengths of light to measure your pulse rate and how much oxygen is in your blood. The screen of the oximeter shows users a digital display of the percentage of oxygen in your blood as well as your current pulse rate.
Why are people buying oximeters during the COVID-19 pandemic?
Because COVID-19 is a respiratory virus, it affects a patient’s ability to get oxygen into the body. While current advice, if you are worried that you have COVID-19, is to stay home and monitor your symptoms, some people believe that using an oximeter could indicate when a person’s lungs are struggling and a doctor needs to be called.
What is a healthy reading on a pulse oximeter?
Advice from medical professionals is to focus on the trends of measurements, rather than a specific number. If you use the oximeter regularly and the number drops each time, that may be cause for concern and you should call a doctor. In general though, a healthy adult’s reading should be above 92%.
