The Nurse’s Pulse Oximeter Buying Guide


Many pulse oximeters will have the same features, but not all will have the same quality. There are 6 things you should look at when you’re shopping for the right pulse oximeter for you.

using pulse oximeter



You need an accurate reading every time. Most will have an accuracy indicator. It should be at least within 2% of lab standards (arterial blood gas test).


Battery Life

Whether it’s a rechargeable battery or regular batteries, a pulse oximeter with longer battery life and lower energy consumption is going to save you the annoyance of having it shut off while you’re using it.

Our selection all have great battery lives of up to 40 hours (that’s a long time).



In a display, you should look for one that has large, easy-to-read numbers and indicators. A nice addition is a backlight to see in low light conditions.



Alarms and alerts are an easy way to let you know that something is off with the patient’s SpO2. Look for a pulse oximeter with an alarm and alert function.



If you’re going to be using your pulse oximeter a lot, make sure it’s made from quality materials. A good feature to look for is one that is shock-resistant in case you drop it.



There are many types of fit, especially if it’s a pediatric model. Make sure it is a universal fit or specifically for pediatrics. It should fit the finger easily, while still remaining snug. Mest pulse oximeters measure ½ inch to 3 inches.


What Are The Types Of Pulse Oximeters?


In general, there are three types of pulse oximeters: medical-grade, home use, and sports models. All are great for checking the SpO2 levels in the bloodstream, the only difference being that the medical-grade models have a higher degree of accuracy.


Medical Grade

Medical grade pulse oximeters have a degree of accuracy within a 2% margin of error. These are rated for clinic and hospital use.


Home Use

Even some home models have the same degree of accuracy as medical models, even though they’re not hospital-rated.



Sports models are often made to be worn while exercising to measure how the athlete’s body is processing oxygen; a way to measure fitness and lung capacity.

Three different models of pulse oximeters:

There are three general types of pulse oximeters – two clip-on styles and a cuff style.

  • Finger clip – made to clip on to a patient’s finger snugly
  • General clip – this type of clip is flatter, more like an alligator clip so it can be attached to an ear lobe.
  • Cuff style – the cuff style can be worn around the wrist. Many sports models are cuff-style and are also used overnight to measure SpO2 while patients are sleeping.


What Does A Pulse Oximeter Measure?


A pulse oximeter measures the amount of oxygen in the bloodstream, or saturation level (SpO2). To do this, it sends two types of light (infrared and red) through a fingertip or earlobe and measures how much light is absorbed.

According to what type of light is absorbed and how much can determine how much oxygen is in the bloodstream.


Which Finger Is Best For Accurate Pulse Oximeter Reading?


Although some studies showed a slightly elevated SpO2 reading on the right middle finger, the variance was slight enough to be statistically insignificant.

Most use either the right middle finger or index finger – both will give you an accurate reading (however the thumb and pinky aren’t recommended).
