What are the Normal Ranges for a Pulse Oximeter?

Heart Rate – The heart rate or pulse is different in different people, and thus the normal range is anywhere between 60 to 100 beats per minute.

Oxygen Saturation or SpO2 – The normal range is between 94 to 100 percent. Anything below 90 is referred to as hypoxemia, and the patient should be immediately taken to the doctor. However, don’t panic.

How to Use a Pulse Oximeter?

Using a pulse oximeter is quite simple.

You just clip it on one of your fingers and turn it on.

Within seconds, the large bright display gives you a readout of the blood oxygen saturation levels and heart rate.

Which Finger is Best Suited for taking Accurate Readings using Pulse Oximeter?

Accuracy is often the primary concern in measuring oxygen saturation levels using a pulse oximeter.

Interestingly, a few years back, a study observed how clipping each finger affected the results.

The verdict was that the middle finger of the right hand gives the best accuracy.

However, most people using a pulse oximeter today just randomly clip it to their index finger and take readings.

What things affect the Accuracy of a Pulse Oximeter?

Nail Polish – The light from the pulse oximeter cannot adequately penetrate the finger with nail polish and hence gives you erratic results. One should also not use fake nails while using a pulse oximeter. Further, make sure your nails are not very long.

Cold Hands – A cold hand usually reduces the accuracy of the pulse oximeter readings. It is suggested to warm up your fingers a few minutes before using the device.

Movement – To get reliable readings, try to minimize your movement and remain stationary. Also, keep your finger below the level of your heart.

What are the Risks of using a Pulse Oximeter?

Thankfully, there aren’t any risks or dangers of using a pulse oximeter.

The only concern is making sure that the device is giving an accurate reading.

So, feel free to use it any number of times in a day and on anyone without a worry.

Did You Know?

Did you know that there are smartphone apps claiming to measure oxygen saturation using just the phone’s built-in camera and flash? While these apps are convenient, they may not be as accurate as dedicated pulse oximeters. It’s crucial to exercise caution and skepticism when relying on them for medical purposes.
