Pulse Oximetry Uses and Benefits

With pulse oximetry, you can find out how much oxygen is in your blood. If you or one of your loved ones have been suffering from a cardiovascular or respiratory condition, we suggest that you opt for a pulse oximeter. Read on to know more about the functionalitiy and benefits of using one.
What is pulse oximetry?
Your organs need oxygen to work properly. Without oxygen, your body cells will not be able to function properly and you will die soon. As a matter of fact, cell death may cause a lot of symptoms and the organ may fail before long.
Actually, your body supplies oxygen to your organs once the oxygen has been filtered via the lungs. Then the lungs provide oxygen with your blood through the hemoglobin proteins found in your red blood cells.
What pulse oximetry does is measure how much oxygen is in the hemoglobin proteins. This is known as oxygen saturation, which shows how much oxygen your organs are getting. Normally, it is between 95 and 100 percent. Moreover, if this level falls below 90%, you should get medical assistance as soon as possible.
How pulse oximeters work
Actually, these devices can be attached to a foot, wrist, finger or other devices for measuring the oxygen saturation. Oxygen saturation may fall below the minimum level due to many reasons, such as drowning, choking, infections, and suffocation, just to name a few.
These devices shine a light through some transparent area of your skin and then the light shines through to the powerful sensor fitted on the other side of the wrist. Now, the amount of light that your blood absorbs shows the oxygen saturation. Actually, this device doesn’t get the measurement directly. Actually, it makes use of a complex equation for estimating the exact level.
