  You should purchase the oximeter at home because it is very much required in the current pandemic situation. It can be a good idea to monitor your oxygen saturation at home. If they are consistently decreasing into the lower 90s, that would be a reason to contact your doctor.

  It works by painlessly flashing through the pad of your finger or earlobe with a special red light and detecting how much can be seen from the other side. Based on how much oxygen is carried by the hemoglobin of the blood, light is consumed differently. The display displays a number which reflects the oxygen percentage of hemoglobin. For most people, the “oxygen saturation” is in the high 90s. When someone develops lung problems, the amount of oxygen in the blood falls, and the oxygen saturation decreases.
