What is a pulse oximeter?


A pulse oximeter is a device used to quickly and easily monitor a person’s blood oxygen saturation. This means that the oxygen level in the blood, especially in the arterial blood, can be measured without using any invasive means.

A pulse oximeter is usually a small portable device that can be clamped on a finger and provides a reading within a few seconds. In addition to measuring oxygen saturation, the device also provides heart rate measurement.

Arterial blood flows from the heart to all parts of the body, filled with oxygen, and then spreads to the surrounding tissues and cells. If there is a lack of oxygen in the blood, this means that your body tissues will not be properly oxygenated and may endanger your health.

This may indicate severe lung disease.

This is why the use of a pulse oximeter is so important. Respiratory therapists (and other healthcare professionals) use these portable fingertip pulse oximeters to continuously monitor the oxygenation level of patients.
This also helps to better understand their overall cardiorespiratory condition.

It is also recommended that patients with cardiopulmonary disease also keep their pulse oximeter for family use. That’s why we created this list to provide you with the absolute best choice in one place.

Best of all, each of the high-quality pulse oximeters listed below can be purchased on This means you can use a high-quality pulse oximeter in just a few days.


Pulse oximeter type

When it comes to different types of pulse oximeters, there are two types: 1) medical grade; 2) sports and home use. Both can be called fingertip pulse oximeters because the finger is the most common location for taking readings.

Doctors, respiratory therapists and medical professionals use medical-grade pulse oximeters in clinical settings. It can only be purchased from medical supplies manufacturers.

In the household, it can basically be attributed to different brand names. This article focuses on helping you choose the type that suits you.

How does the pulse oximeter work?

The working principle of the pulse oximeter is simple and sophisticated. Blood absorbs light, and there is a significant difference between the wavelengths of oxidized and deoxygenated blood.

The finger clip of the pulse oximeter consists of a transmission light source that emits broad spectrum light. At the other end, there is a receiver that measures how much light passes through.

The diode at the receiving end can detect the wavelength of the light. The internal circuit and processing components of the pulse oximeter also perform some calculations.

The device must compensate for ambient light, the size of the finger, and the absorption rate of the rest of the tissue.

A reference curve is stored in the device’s memory to calibrate and normalize the input readings. This improves the accuracy of the results it provides.

What does a pulse oximeter measure?

Pulse oximeter mainly measures the percentage of arterial oxygen. More precisely, this is the amount of oxygen carried on the hemoglobin in the blood. It is called SpO2.

Another way to think of the result as oxygen saturation. This is the expression of the ratio between oxygenated blood and deoxygenated blood.

After measuring the oxygen saturation, you will encounter some parameters. Heart rate (HR) is automatically calculated with oxygen percentage.

HR and SpO2 complement each other, and clinicians find this dual parameter reading very useful.

How to use a pulse oximeter?
The best part of pulse oximetry is that it is non-invasive. In the past, doctors had to draw blood from patients and perform several analyses to find out the percentage of oxygen saturation.

Using a pulse oximeter is very simple. You clamp it on your right middle finger, toe or earlobe. Some models are surface probes that can be attached to the forehead or chest.

In order to obtain reliable and true readings, please minimize patient movement. Also, if you are using a finger clip, please make sure that there is no nail polish.

These simple measures are sufficient to obtain an accurate representation of arterial blood oxygen saturation.
The reading is displayed after a few seconds, which is another important function of the pulse oximeter. It is useful in emergency situations and where continuous real-time monitoring of patient vital signs is essential.

Which finger is best for pulse oximeter?

Pulse oximetry is not a new technology. It was implemented around the 1980s, but since then many advances have been introduced. Usually to increase the reliability of readings.

Accuracy is usually the main issue in measuring oxygen saturation, and an interesting study in 2015 observed how trimming each finger affects the results.

The conclusion is that the middle finger of the right hand has the best accuracy. Then the thumb of the same hand appeared.

For clinicians and doctors, this is a surprise. The same study showed that about 80% of medical staff would naturally pinch the index finger of a patient.

What are the risks of pulse oximeters?

Fortunately, there is no risk or danger in using a pulse oximeter. The biggest concern is to ensure that the device gives accurate readings.

This is especially true for doctors, respiratory therapists and medical professionals. Because if the pulse oximeter results are inaccurate, it may lead to poor treatment and care of the patient.

What is the normal range of a pulse oximeter?

We have discussed the measurement method and working principle of the pulse oximeter. Now we need to talk about the normal range of heart rate and blood oxygen saturation.
Heart rhythm-60-100 beats/minute
Oxygen saturation-95-100%
Remember, these are normal values ​​for ordinary adults. The range depends on your age. Although the normal blood oxygen saturation range is 95-100%, it is not considered dangerously low until the blood oxygen saturation drops below 90%.
In this case, this is called hypoxemia, which means that the amount of oxygen in the blood is abnormally low. Hypoxemia is treated with supplemental oxygen.


Should you really buy a pulse oximeter at home?

The answer to this question really depends only on your own unique medical condition. Under normal circumstances, for those with lung diseases (such as COPD and asthma), only a pulse oximeter is needed at home.

However, these are far from normal. At the time of writing, the global epidemic is in 2020, and it is wise to buy a pulse oximeter that can be kept at home to monitor your blood oxygen saturation level. Especially, if there is no other reason, you can relieve anxiety and give you peace of mind. Of course, you must consult a doctor.
