Our Picks: How we picked the best pulse oximeters

Know all about the top seven pulse oximeters of 2021.

1. Features: Most important purchase criteria for pulse oximeters

1.1 Types

There are five(531.43) types of pulse oximeter available in the market, and they are as follows:

  1. Finger Pulse Oximeter: Also known as portable pulse oximeters, these are used on the fingertips. You have to simply clip the oximeter on your finger (preferably the index finger), and the display screen will give you the results in no more than 10 seconds. They are lightweight, compact and portable.

    They are battery operated pulse oximeter and are usually used at home to check blood oxygen levels.

  2. Handheld Pulse Oximeter: The handheld oximeters are better than the finger pulse oximeters since they give more accurate results.

    This type of pulse oximeter consists of 2 parts – the probe and the display screen. These two parts are connected via a cable, and the screen is handheld. The probe is to be attached to the finger (preferably the index finger), and you can see your blood oxygen levels on the screen.

    It provides continuous oxygen saturation monitoring and is commonly used in clinics, hospitals, emergency medical services (EMS), and medical institutes.

  3. Wrist-Worn Pulse Oximeter: As the name suggests, a wrist-worn oximeter is worn on the wrist, and it is excellent for continuous monitoring. Doctors usually use this type of oximeter to measure your blood oxygen level while you are sleeping.

    It also has two parts - the probe and display screen. They are connected through a short cable. The probe is to be attached to the patient's finger, and reading can be seen on a screen worn on the wrist.

    Some of these oximeters are capable of storing the data, which can be transferred via Bluetooth. Some models also come with USB connectivity to make the data transfer job easier.

  4. Tabletop Pulse Oximeter: These oximeters are similar to handheld pulse oximeters but a bit bigger than them. It also consists of a probe and the display screen that are connected using a cable. They are used in hospitals and other medical facilities. They allow checking of the plethysmograph, due to which they are preferred for monitoring newborns, kids, and adults. They can even store data of the patients. Tabletop pulse oximeters also come with audio and visual alarms that warn the user if there is a low pulse rate or blood oxygen level.

  5. Pediatric Pulse Oximeter: As the name goes, this type of oximeter is used by paediatricians to monitor infants or kids below an age group of 4 years. These are finger pulse oximeters designed especially for the tiny fingers of the babies.

    Some pediatric pulse oximeters come with an alarm feature to alert you whenever the oxygen saturation level is low. And since it is designed for children, most of them have an anti-motion feature, so, despite the child is moving the hands, the device provides accurate results.

3.5 What are the conditions that can possibly affect pulse oximeter readings?

Nail polish colour and decals can affect the oximeter readings, and so can acrylic or gel nails. Besides, anaemia, low blood pressure, skin with more pigment, low body temperature, and intravascular dyes can also affect the readings of this pulse checking tool.

3.6 How does a pulse oximeter work?

The pulse oximeter is used to measure the oxygen quantity carried in the blood haemoglobin, also called SpO2.

The oximeter uses light to monitor the oxygen saturation level. Once it is clipped to your finger, toe or earlobe, it passes red and infrared light through the body part to which it is clipped. The two lights work together to analyse the haemoglobin. The wavelength of the red light is around 650 nm, and that of infrared light is 950 nm. The haemoglobin with oxygen (oxy Hb) generally absorbs more infrared light and deoxy Hb absorbs more red light than infrared light.

Further, the pulse oximeter compares the amount of red light and infrared light absorbed by the blood. So, if the red blood cells have 95% oxygenated and 5% non-oxygenated haemoglobin, your SpO2 would be 95%.

3.7 What is the ideal pulse in an oximeter?

Usually, experts suggest that regular pulse oximeter readings range from 95 to 100 per cent. Reading below 90 per cent is considered low and indicate supplemental oxygen requirement.

However, for people with chronic lung conditions and other breathing problems, the range of 95% to 100% doesn’t apply. These individuals should instead consult a doctor. That being said, here are some usual guidelines for individuals with acute respiratory issues and chronic diseases:

  • For people with acute respiratory illness or breathing difficulty, an SpO2 of 92% or less may indicate a need for oxygen supplementation.

  • For people with stable chronic disease, an SpO2 of 92% or less refers to further investigation of the need for long-term oxygen therapy.

3.8 How accurate are pulse oximeter readings?

Healthcare experts say that most at-home pulse oximeters give accurate readings. However, the accuracy of pulse oximetry readings can be influenced by various factors, including nail polish, dark pigmentation skin, acrylic or gel nails extensions, low body temperature, low blood pressure, jaundice, cold hands, thick nails, wet skin, bruises or tattoos on the fingertips.

3.9 What are the different signs of low blood oxygen level or hypoxemia?

Following are the common signs of low blood oxygen level:

  • difficulty in breathing

  • fast breathing

  • shallow breathing

  • sucking in the stomach when breathing

  • difficulty while waking up

  • blue-tinged lips or face

If you experience any of the above-mentioned signs, no matter what your finger pulse oximeter says, seek emergency medical attention.

3.10 Is it safe to rely on an oximeter in case of carboxyhemoglobin?

Carboxyhemoglobin refers to the situation where the carbon dioxide levels in the blood shoot up. If such is the case, verify the pulse oximeter readings by using a blood-gas analysis.

Though the pulse oximeters can treat pulmonary and circulatory ailments, they can’t distinguish between the haemoglobin cells carrying oxygen and carbon dioxide. Therefore, relying entirely on the oximeter readings can be risky in such situations. Consult your doctor immediately.

3.13 Can a pulse oximeter help in detecting coronavirus?

A pulse oximeter can help in detecting the symptoms of the diseases.

The strain of coronavirus enters the body via the respiratory system, directly affecting the lungs and often resulting in inflammation or pneumonia. It eventually reduces lung efficiency and the amount of oxygen in the body. Therefore, the pulse oximeter helps in detecting coronavirus symptoms more quickly.

3.17 Why is my oximeter not showing any reading?

Pulse oximeters work when the sensor is able to detect light passed through body tissue and the amount of light being absorbed by haemoglobin. If ambient light enters the probe site, this will stop the pulse oximeter from producing a reading at all or giving an incorrect reading.
