However, it is important to note that the moment you develop symptoms or start feeling breathless, it is strongly advisable to consult your doctor instead of relying on a small device. Infact, if you continue getting good oxygen saturation level on the pulse oximeter, it may dissuade you from seeking treatment for other symptoms of COVID. Buying an oximeter might be useful if you are suffering from high blood pressure, diabetes and other chronic lung and heart conditions, which put you in the high-risk category for COVID-19.
Most individuals do not need a pulse oximeter at home unless they feel that have been exposed to the virus or have co-morbidities putting them at high-risk. Even then, the device should be used with a doctor’s guidance to get accurate results and to prevent panic.
