Best Pulse Oximeter

Thanks to the increasing awareness about our health, almost every home has now commonly used medical gadgets such as sphygmomanometer, thermometer, glucometer, etc. A pulse oximeter is a recent addition to that list that has made its way into our lives.

A pulse oximeter is an easy-to-operate non-invasive device that is used for measuring the amount of saturated oxygen in the blood. Moreover, it also displays the pulse rate of the user. It can be used by anyone at home irrespective of age or gender. 

It is a compact device that can be easily carried into your pocket or stored in a small space within your medical kit. It comes in very handy in taking required medical measures beforehand when the patient’s blood oxygen level drops at dangerously low levels.

We all have heard of  that we keep at our house so we can have all the stats from time to time.

In this article, you will find how a Pulse Oximeter works, its types of oximeter followed by Buyer’s guide and benefits to help you make the right decision along with answers to frequently asked questions and our list of Best Pulse Oximeters in India.

How a Pulse Oximeter Works

Just like Blood pressure monitors and sleep trackers , an oximeter is also a must-have device if you wish to accurately monitor your health.

To use an oximeter, the probe of the pulse oximeter is clamped on a thin part of the patient’s body, such as a fingertip or an earlobe. The probe then sends two wavelengths of light through the body part to a photodetector, i.e., a receiver.

Oxygenated hemoglobin absorbs one of the two wavelengths of light, while deoxygenated hemoglobin absorbs the other wavelength. The photodetector or receiver analyzes the two wavelengths after they have passed through the body part and determines the blood oxygen level.

Benefits of Using a Pulse Oximeter

  • Monitors the saturation of oxygen in the blood for those suffering from sleep apnea and severe snoring.
  • They help in warning the hospital staff in case the oxygen level in the blood of an infant or any vulnerable patient becomes dangerously low.
  • Helps in monitoring pulse rate and Spo2 during exercise or any other physical activity, especially for someone suffering from cardiovascular and chronic respiratory conditions.
  • It measures the saturation level of oxygen in the blood for those under anesthesia.
  • Notifies you when the readings are beyond the limits.

Types of Pulse Oximeters

There are five types of pulse oximeters that are available in the market. They are:-  

Finger Pulse Oximeters

Finger Pulse Oximeter

Finger pulse oximeters are also known as Portable pulse oximeters. As the name suggests, such oximeters are small and portable and are generally used on the fingertips.

The oximeter is simply clipped on the finger, and the display screen is on the probe itself. When the oximeter is clipped on the finger, the results are shown on the screen, almost instantaneously.

Such oximeters are battery operated and are very useful to check blood oxygen levels at home. The easy use of such oximeters, portability, and affordability, makes it ideal for use at home, clinics, caregivers, or by patients themselves.

Handheld Pulse OximetersHandheld Pulse Oximeter

Handheld pulse oximeters are more sophisticated than finger pulse oximeters and are capable of producing more accurate results.

A handheld pulse oximeter has two parts, the probe and the display screen, which is a handheld screen. The two parts are connected via a cable. The probe is attached to the person’s finger; ideally, the index finger and the blood oxygen levels are shown on the screen.

Such pulse oximeters are capable of continuous oxygen saturation monitoring. They are mostly used in hospitals, ambulances, medical institutes, and emergency medical services (EMS).

Tabletop OximetersTabletop Pulse Oximeter

Tabletop oximeters are bigger than handheld pulse oximeters and are very similar to handheld oximeters. Like handheld oximeters, tabletop oximeters also have two parts, the probe, and the display screen, connected by a cable.

They are generally used in hospitals, medical facilities, and home care centers/settings. Some tabletop oximeters come with audio and visual alarms to warn people around when parameters like blood oxygen level and pulse rate fall below the safe range.

Most tabletop oximeters also come with plethysmograph display and are suitable for monitoring adults, kids, and neonate patients. They even come with a provision to store data or logs for several patients, even up to 100 in some cases.

Wrist Worn OximetersWrist Worn Pulse Oximeter

Wrist worn oximeters are just like the wrist watches that one wears. This type of pulse oximeter is used for continuous monitoring.

In many cases, the doctor may want to monitor your blood oxygen levels constantly, or during your sleep, wrist-worn oximeters are ideal for such cases.

The probe is attached to the patient’s finger, and the readings are displayed on a screen that is worn on the wrist, just like a wrist watch. The probe and the screen are connected by a short cable, which will not be a hindrance as you go about your daily work.

Such oximeters are capable of storing data as well. Some oximeters even have wireless connectivity via Bluetooth for wireless data transfer, while others have USB connectivity for the transfer of data.

Pediatric Pulse OximetersPaediatric Pulse Oximeter

Pediatric pulse oximeters are oximeters specially designed for kids, especially infants below the age of 4. They are finger pulse oximeters but built and designed to cater to kids and their smaller fingers without any problems.

Regular finger pulse oximeters are bigger and cannot cater to the smaller fingers of kids. Hence, pediatric pulse oximeters are used to monitor the blood oxygen levels for children and infants.

Some pulse oximeters come with an alarm when the pulse rate or oxygen saturation level goes below the safe range. Some of these pulse oximeters even have an anti-motion feature, which will help you get an accurate result, despite the child moving his/her hand.

Pulse Oximeter Buyer’s Guide

In purchasing a pulse oximeter, there are certain things to consider. Putting these into consideration will get you the best pulse oximeter.


The best option is to choose an oximeter you can afford. A costly oximeter can attract a high maintenance fee, and also give you more durability. Low cost oximeters have a small maintenance fee, but are less durable.

Warning System

It’s good to choose an oximeter with an excellent warning system. A suitable oximeter will produce an alarm warning you about your steady heartbeat and also your irregular heartbeat.

For those who rely on pulse oximeters for disease management, an indicator for a low battery to be able to maintain their health adequately.


Some oximeters can be very portable and also bulky. Therefore, choosing an oximeter that is lightweight is a good buy. These lightweight oximeters can be kept in your pocket without feeling uncomfortable.

Any individual suffering from hypoxia will need a lightweight oximeter, and it is almost impossible for a light weighted oximeter to get damaged or destroyed by careless management.


Durability is an essential factor in choosing the best pulse oximeter to buy. A strong pulse oximeter will provide the best result at all times. So, selecting a pulse oximeter that is not durable will put your life at risk in several scenarios.

A quality pulse oximeter should be able to withstand hard impact with the ground and possess a waterproof structure to prevent damage from water and humidity. The durability of an oximeter will avert the failure of the device and prevent inaccurate readings.

Visible display

There are several pulse oximeters with different styles or display and font color. Therefore, it’s crucial to choose a pulse oximeter with the perfect display of your choice and right font size.

It’s also essential to select a pulse oximeter with a beautiful backlit display. Under severe lightning conditions, some of the best pulse oximeters have adjustable brightness that is needed during these conditions. Y

ou can also look for pulse oximeters with multiple angle displays to improve your visibility during usage.

Accuracy and Reliability

The very first thing that one should look for while purchasing a pulse oximeter is its accuracy and reliability. The primary purpose of a pulse oximeter is to measure your blood oxygen level and pulse rate.

The key is to find a pulse oximeter that can produce accurate results consistently and reliably. Most pulse oximeters use the same mechanism to produce readings, and the only difference lies in the way they are manufactured.

Unfortunately, the only way to check whether a pulse oximeter is accurate or not is by cross-checking the results it produces with another one, such as one at your doctor’s office or other medical clinics.

Most oximeters should be capable of producing results within a few seconds with an accuracy of ±3%.

The accuracy of the oximeter is affected by motion. So, if your hand trembles, find an oximeter that has an anti-motion feature, which will still be able to produce accurate results.

Ease of Use:

A pulse oximeter should be easy to use and should not need much technical or special knowledge.

Finger oximeters are very easy to use, and they involve just clipping the oximeter on your finger and pressing a button, and voila, there is your result on the screen. Also, a large screen will make life easier, enabling easy reading of the results.

Some oximeters even display the results differently, making them easier to read and understand. All these are added benefits that will make it a lot easier to use a pulse oximeter. And that’s the way a pulse oximeter should be- easy to use.

Size of Probe

Check the size of the probe while purchasing a pulse oximeter and ensure that the probe fits on your finger snugly and comfortably. This is generally not an issue with the clip-on type of probes, where the probe can simply be clipped on to the finger without any fuss.

If you are looking to check the saturation oxygen for kids and infants, or even people with smaller hands or fingers, you could consider buying a paediatric pulse oximeter, which would be more suitable for that application.

Other Features

Some other features that could be a bonus are features such as memory for storage of data and multi-person memory wherein data for more than one person can be stored.

Other features could include Bluetooth connectivity or USB connectivity to transfer data to a system, where it can analyze further.

Short cables that would not create much of a nuisance would help. An oximeter, which is not very bulky and portable, would come in handy and can be easily stored as well.

Some pulse oximeters are even capable of generating other statistics such as a plethysmograph and perfusion index, which could also help in getting a better diagnosis.

Not all pulse oximeters produced come with a graph displaying if your heart is beating abnormally. But it will be advisable to buy an oximeter of your choice that includes a chart to display if your heart is beating abnormally.

3. Is there any battery aside from the regular battery in the description?

All pulse oximeters use AAA batteries; it might be challenging to acquire an oximeter that doesn’t use AAA batteries.

4. Are there pulse oximeters for infants?

Yes, there are. Though not all oximeters are recommended for infant use, some oximeters can be used on an infant.

5. Is every pulse reading stable?

Yes, all pulse readings are stable. This can be achieved if you aren’t connected or close to a defibrillator or an oxygen source that will cause an incorrect interpretation.

6. Is it compatible with every location?

The oximeter readings are not affected by location.

 7. Do pulse oximeters measure co2 retention?

No, a pulse oximeter measures oxygen in blood and pulse rate.

8. Does it keep permanent records?

No, it doesn’t keep permanent records. As long as the power is on, it will keep updating oxygen and pulse rate readings, but once the power is turned off, the readings are lost.

9. What is the normal range of pulse oximetry?

The normal range of arterial oxygen is 75 to 100 mm of Hg. Anything below 60 mm of Hg is low and requires an oxygen supplement. The Oximeter readings range between 95 to 100 percent, anything below 90 percent is low.

10. What is Spo2?

This is known as blood oxygen saturation. It is the measure of the amount of oxygen-carrying hemoglobin in the blood relative to the hemoglobin, not carrying oxygen. If the Spo2 level is less than 95 percent, it is a sign of the poor level of oxygen in the blood; a condition called hypoxia.

11. Are pulse oximeters accurate?

Yes, most pulse oximeters ensure accurate readings. However, the readings could be less accurate if the person has cold hands, is wearing nail polish, artificial nails, or has poor circulation.


A pulse oximeter is an affordable and useful medical gadget that helps you to monitor your blood glucose levels quickly within no time. The best part is that it is a non-invasive device that gives you readings of blood oxygen levels by inserting your finger in the device for few seconds. 

It is an ideal addition to your medical kit as it helps in taking timely action whenever the measurements of saturated blood oxygen level get high or low than normal readings. Grab yourself a high-quality oximeter and track the status of your health anytime and anywhere with PR and blood oxygen readings.    

If you are not sure which product to go for, we would suggest the oximeter from Dr Trust Professional Series is one of the most popular options due to the wide number of features it offers. Meditive Finger Tip Pulse Oximeter  is a good choice if you are on a budget.
