Pulse Oximeter (Fingertip)

What is a Pulse Oximeter?

A pulse oximeter helps people monitor oxygen by using light beams to estimate blood oxygen saturation and pulse rate (similar to heart rate). Oxygen saturation gives you information about how much oxygen is in your blood cells. Pulse oximeters can also measure tissue perfusion, which is the amount of blood that flows through your circulatory system.

How to Use a Pulse Oximeter

According to the FDA, the proper use is reached by first washing your hands, removing any nail polish on the finger you plan on using, making sure your hand is warm, placing the oximeter on your finger, and holding it below the level of the heart. Typically the middle finger on the right hand is used for the most accurate measurement. Sit still and wait a few seconds until the reading displays one steady number.

Be sure to also follow the manufacturer’s instructions for the individual device you are using.

Pulse oximetry might be recommended by your doctor if you have a condition that affects your oxygen levels. Some examples include long-term heart or lung problems or asthma. Additionally, if you have symptoms of the Coronavirus, that might be a good time to check your oxygen levels.

Based on the above, it’s clear that pulse oximeters can offer a lot of valuable information about one’s health. Knowing your blood oxygen saturation (SpO2) and heart rate at any moment is valuable knowledge. Because of this, it’s important to purchase a device that is reliable and trustworthy. 

How to Read a Pulse Oximeter

Pulse oximeter readings are fairly easy to interpret. Most devices will display two numbers, the number next to “PR” is your pulse rate and the number next to “SpO2” is your blood oxygen saturation. When taking pulse oximeter readings, pay attention to how the results compare to previous readings. Changes or trends might be more meaningful than one single measurement.

What is a Normal Oxygen Level?

According to the FDA, most healthy individuals have an SpO2 value between 95%-100%. A value lower than 95% is considered a low oxygen level. Below 92% indicates a very low reading and potential hypoxemia (low oxygen levels in the blood).
