Pulse Oximeter

101 Easy Guide to Pulse Oximeter:


The Pulse Oximeter is a clip-like medical device used to measure the level of oxygen saturation in the blood. Normally this device is put on the finger which with the help of its sensors senses the oxygen saturation level along with recognizing your heart rate.

The best part of Oximeter is that the test is painless, very simple to use, and understands the reading. So without delay let’s find out the way to use the Pulse Oximeter.

Steps in using the Pulse Oximeter

Step 1 Remove Nail Polish and trim your Nails before using Oximeter

Removing your nail polish is important as the Pulse Oximeter uses light sensors to identify the oxygen saturation level in the blood. Using the nail polish might disrupt the scanning process through the light which will result in a false reading. Further, make your nails short so that it’s not only easy to place your finger inside the device but also the reading will not be affected due to the issue in positioning.

Step 2 Place your Oximeter in the finger (Positioning the Oximeter Correctly is the key)

The most preferable finger to use is the middle finger as it receives high blood flow as compared to other fingers. Also, give proper care to not make the probe too tight or too loose which will affect later in the reading outcome. Thus, if you feel too loose or too tight consider using other fingers.

Step 3 Press the button and wait for some time

Before starting measuring, make sure your hand is not cold and you are sitting calmly. You can also check your oxygen level while at rest and after some exercise to get more insight into the change in the level of your oxygen saturation level.

If you see the triangle-like shapes that are moving along the display, then it is the sign that your Oximeter is fine and carrying out the reading well.

Step 4 Test two or three times so that the margin of error is reduced

Sometimes the value might fluctuate due to some reason. So to reduce the margin of error and be more confident in getting the actual reading to repeat the test twice or thrice. Once you have taken the measurement, you will notice the trend which will help you give more confidence in the value of the reading.

Understanding the reading of Pulse Oximeter

For Normal Person

The normal Oxygen Saturation level SpO2 level is 95% to 100%

If the oxygen saturation drops to 90%, monitor the patient as they might need the aid of oxygen.

For persons with chronic breathing-related issues

There is no such thing as normal level of oxygen level for the patients as the case may vary. The Oxygen saturation level at 91% to 94% is called Mild Hypoxemia, in such cases, essential care should be given to the patient by regularly monitoring their oxygen saturation level and check if they are having any breath-related issues.

If the patient’s oxygen level is decreasing try to put them in a prone position and tell them to take a deep breath and exhale in a rhythm. If further, the oxygen level drops from 91%, the patient must be provided with oxygen.

The Pulse Oximeter is the most useful device and its application is immense in this precarious situation now than ever before. So folks, go and get your Pulse Oximeter sooner rather than later.
