How to choose the right finger pulse oximeter?

What is a pulse oximeter? 

A pulse oximeter is a non-invasive medical device that is used for measuring the pulse rate and the oxygen level in the blood. It is especially preferred in situations when an immediate and accurate reading of blood oxygen saturation and pulse rate is needed. 

The accuracy and level of precision are just some of the pre-requisites for choosing a pulse oximeter. So, what are the other points that you must know to understand if a finger pulse oximeter is right for your use?


Accuracy forms the bedrock of choosing this device. For you to rely on an oximeter, you need to ensure that it provides nothing but exact readings. 


Another important factor to look for before buying an oximeter is to know whether the oximeter will work for a wide range of patients or not. Make sure to opt for the oximeter that accurately lists for even the people with low perfusion or dark skin tones. 

If the device automatically adjusts to each patient quickly and accurately and can also accommodate a wide range of finger thicknesses, then you've found the right match! 


Always choose the oximeter of the brand that offers the best warranty and has a great reputation for providing the best customer service.


The pulse oximeter that can effortlessly function even in the most demanding environments and can allow for thousands of uses is the one that you should certainly opt for. 

Also, check that the finger pulse oximeter you intend to buy protects against dropping and water spills also. Buying a device with low durability will result in a higher cost as you will have to keep replacing it. 

Need for calibration

Do check if the oximeter requires calibration or if it can provide accurate readings on its own. 


One of the best oximeters is the one that is simple to use and has an easy-to-read, bright LED display. 

Presence of lead

Make sure to find out whether the oximeter you are interested to buy is lead-free or not.
