Top 10 Best Wrist and Fingertip Pulse Oximeters
What is a Pulse Oximeter?
According to the American Lung Association, “The pulse oximeter, or Pulse Ox, is an electronic device that measures the saturation of oxygen carried in your red blood cells.” The device can be attached to your fingers, forehead, nose, ears, wrists, foot, or toes. It is an easy and painless way to measure how well oxygen is being sent to parts of your body furthest from your heart, such as the legs and arms. If you are experiencing shortness of breath or have a known heart or lung condition, your doctor may use a pulse oximeter.
The device is also used in home settings for people who have underlying health conditions. You can also find them on Amazon, in pharmacies, and medical supply stores, although prices and quality can vary widely.
Note: If you are using it in a home setting, it is vital to consult your healthcare provider so that they can guide you with the interpretation of the results.
How does it Work?
Pulse oximetry works with the use of red and infrared light. After clipping the device onto a body part, one side shines red and infrared LEDs through a relatively transparent portion of the skin. It is where there is good blood flow, while the other side receives the light. The principle of the technology is that oxygenated hemoglobin can absorb more of the infrared light which allows more red lights to pass through. By analyzing the light from the light source that passes through the finger, the device can determine the percentage of oxygen in the red blood cell.
The device also shows the pulse rate. A resting pulse rate of 60 to 100 beats per minute is average, though athletes can have even lower rates. An increased or decreased heart rate that differs from your average can be concerning.
✅ Video – How does Pulse Oximetry Work?
Below is a video shared on YouTube by the Respiratory Therapy Zone. It tackles pulse oximeter and how it works. In the video, how to use a pulse oximeter is also discussed as well as what an oximeter measures. For an in-depth discussion, you can watch the video below.
Why are People using it to Detect COVID-19?
Shortness of breath is among the symptoms of COVID-19. Many patients with severe cases have deficient levels of oxygen in the blood. Others who have tested positive are experiencing shortness of breath. Maybe this is one of the reasons why people are interested in buying and using pulse oximeters. This device measures the saturation of oxygen in red blood cells.
Increasing Demand for Pulse Oximeters in the U.S.
The COVID-19 pandemic has sparked an interest in pulse oximeters. You can find tutorials on YouTube and social media with instructions on how to purchase pulse oximeters to monitor whether they have COVID-19 or not. Take note that doctors discourage patients from using homegrown measures, as well as any device that isn’t FDA-approved.
Many models are also sold out on online stores and pharmacies. According to Quartz, U.S. sales of pulse oximeters spiked on January 20 when the country’s first COVID-19 case was confirmed.
Do You Need to Get One?
✅ Tweet – Chris Cuomo Shares Details of His Symptoms
In the tweet below, The CNN host Chris Cuomo shares what it was like to experience the effects of Coronavirus. The 49-year-old host, who is the younger brother of New York Governor Andrew Cuomo, said that he even had a hallucination of his late father, former New York Governor Mario Cuomo, who died five years ago. He also shared that people have been sending him pulse oximeters, which are hand-held devices that read your body’s oxygen levels.
— Cuomo Prime Time (@CuomoPrimeTime) April 2, 2020
According to Shoshana Ungerleider, an internist at Crossover Health in San Francisco, “If you haven’t been diagnosed with Covid-19, or aren’t suspected of having it, home pulse oximeters aren’t necessary.” It especially applies if you are not experiencing Coronavirus symptoms like trouble breathing, chest pain, severe cough, and have not established a baseline.
Stephen Parodi, infectious disease physician and associate executive director of the Northern California Permanente Medical Group also said that the reading mainly is not useful on its own and “It can’t replace a visit or call with the doctor who can assess all of your symptoms and how they relate to any underlying medical conditions you have.”
Moreover, according to Andrew Admon, a pulmonologist at the University of Michigan in Ann Arbor, “It’s not unusual for oxygen saturation to stay normal or close to normal, and then drop suddenly. As a result, normal oxygen saturation can be falsely reassuring.” Healthy people can often maintain normal blood oxygen levels for a long time, even though they are sick. It is because their heart and lungs compensate in other ways.
Even pulse oximeters used at hospitals can deliver inaccurate results. However, hospitals can use other methods of screening, like measuring oxygen levels directly, looking at tracing data from the pulse oximeter, and physically examining the patient. “Without the ability to do this, it’d be hard to separate a poor reading due to a faulty homemade pulse oximeter from a true cause for concern,” according to Admon.
Wrist and fingertip pulse oximeters could be useful for those with several underlying conditions, such as asthma, congestive heart failure, or chronic obstructive pulmonary disease.
But for everyone else? The device may just be an unneeded source of anxiety. According to Jamie Garfield, a volunteer medical spokesperson at the American Lung Association and an interventional pulmonologist at the Temple Lung Center in Philadelphia, “You might check and check and check, and what are you going to do if the number is low?”
Warning People about Pulse Oximeters That is Not FDA Approved
Online stores have many listings for pulse oximeters. However, you need to be aware that not all of them are FDA approved. It is dangerous to use such devices because they are at risk of getting an inaccurate reading. A study in Anesthesia & Analgesia in 2016 looked at a number of inexpensive pulse oximeters that are not cleared by the FDA. They have found out the many of the devices are prone to large errors.
FDA Approved Pulse Oximeter
As we have mentioned above, people should be aware of purchasing pulse oximeters that are not cleared by the FDA. However, if you still would like to purchase one, the fingertip pulse oximeter below has been cleared by the FDA to be accurate within 3 percent for oxygen saturation levels from 70-100 percent.
How About Phone Apps?
Because of the shortage of devices, many people are using oximeters apps. However, take note that Apps that use smartphone cameras to deliver SpO2 measurements can be hit-or-miss. The FDA has not cleared such technology. A study from the University of Alabama and the University of Michigan about three pulse oximeters: iOx, OX, and POx show that all three apps delivered inaccurate SpO2 measurements.
Difference between Wrist and Fingertip Pulse Oximeters
Wrist Pulse Oximeters
This type of pulse oximeter is designed, especially as a blood oxygen level (SpO2) and pulse rate data recorder. They are handy for continuous overnight sleep studies. Wrist pulse oximeters record, monitor, and saves two crucial vital signs, which are pulse rate and blood oxygen saturation level (SpO2), to improve fitness performance and sleep quality.
Wrist pulse oximeters are personal or home use devices. Still, you can use them in sleep studies, cardiac rehab, physical therapy, and other scenarios where it makes more sense to wear an oximeter for a long time.
Fingertip Pulse Oximeters
This type of pulse oximeter is the most popular and probably what you envision when thinking of this kind of device. The device features an alligator clip shape that is attached to the finger. It also features a screen on the top that displays SpO2 and pulse rate levels.
The style varies from the very basic that only reads the SpO2 to the full-featured versions with LED displays. This type of pulse oximeter is the most compact, simple, and affordable.
How to Read an Oximeter
Pulse oximeters can determine the amount of oxygen in the blood with the use of sensors that detect the color changes in the blood due to the movement of oxygen-bound hemoglobin. It is useful for measuring a patient’s respiratory function. According to Livestong, the following are the steps on how to read a pulse oximeter:
Locate the SpO2 reading
It can be found on the digital readout of the pulse oximeter and will be given as a percentage, often between 90 and 100 percent. The location varies according to the type of pulse oximeter used. There are also pulse oximeters with a bar which indicates signal strength. It measures the intensity of the signal that the sensor is generating. High signal strength means that it is less prone to errors.
Usually, patients will have SpO2 levels between 96 and 99 percent. Levels below 90 percent generally indicate acute respiratory failure. On the other hand, the normal range varies from one patient to another. Patients with chronic respiratory diseases may have a SpO2 level below 90 percent without having acute respiratory problems.
Identify the Pulse Rate
The next step would be to identify the pulse rate. Pulse oximeters usually measure the patient’s pulse rate in addition to oxygen saturation. The pulse displayed as a two-or-three digit number (normally between 60 and 100 in an adult and higher in infants and children.) It displays along with a heart shape or the letters BPM (beats-per-minute).
Locate Other Measurements
The last step would be to locate any other measurements on the display screen. There are some pulse oximeters which also show the patient’s ECG and plethysmogram. The ECG measures the electrical activity that the heart generates while beating and can be used to monitor cardiac function and identify arrhythmias. On the other hand, the plethysmogram displays the changes in the amounts of oxygen on the blood that occurs with each pulse. Generally, these pulse oximeters are not available for home use.
✅ Video – Blood Oxygen, Understanding Pulse Oximeter Reading
Rawi Rocharungsat shares the video below on YouTube. It tackles how to read pulse oximeters. He is using a portable fingertip pulse oximeter for home use. In the video, he explains the numbers and reading on the monitor display. He also discussed the average numbers usually shown on the device. Check out the video below for the discussion.
What does a Pulse Oximeter Measure?
Nonin explains that the pulse oximeter measures the oxygen level (oxygen saturation) of the blood and the pulse rate.
Blood Oxygen Saturation (SpO2)
It is an estimation of the amount of oxygen that is in your blood. A reading of 95% or greater is normal. On the other hand, a reading of 92% or less suggests that your blood is poorly saturated. It can cause a range of adverse health conditions, which include chest pain and shortness of breath.
The pulse rate is an estimation of the number of times that your heart contracts per minute. A normal pulse rate for adults ranges from 60 to 100 beats per minute (bpm). Generally, a lower heart rate at rest implies more efficient heart function and better cardiovascular fitness. For some people, a pulse rate below 60 bpm indicates abnormally slow heart action.
Blood Oxygen Meter
Your blood oxygen level is measured on how much oxygen your red blood cells are carrying. Your body closely regulates your blood oxygen level. It is important to maintain a precise balance of oxygen-saturated blood. Usually, children and adults do not need to monitor their blood oxygen levels. Doctors will not check it unless you are showing signs of a problem like shortness of breath. On the other hand, people with chronic health conditions should monitor their blood oxygen level to determine if treatments are working or they should be adjusted.
Who Needs Pulse Oximeters?
You can use pulse oximeters in many kinds of situations, which mainly makes sure that there is enough oxygen in the blood. According to Johns Hopkins Medicine, it can be used for the following:
- During or after surgery or procedures that use sedation
- To see how well lung medicines are working
- Checking a person’s ability to handle increased activity levels
- To see if a ventilator is needed to help with breathing, or to see how well it’s working
- Checking a person has moments when breathing stops during sleep (sleep apnea)
You can use pulse oximeters in checking the health of a person with any condition that affects blood oxygen levels, such as:
- Heart attack
- Heart failure
- Chronic obstructive pulmonary disease (COPD)
- Lung cancer
Types of Pulse Oximeters
All pulse oximeters perform the same basic function, which is measuring the level of oxygen saturation in the blood. However, there are various types of pulse oximeters that you can choose from. Each type has its advantages and disadvantages.
Portable or Fingertip Pulse Oximeter
The fingertip pulse oximeter is portable and is the most commonly used version at home, clinics, hospitals, and other medical facilities. This type of pulse oximeter is the most efficient when it comes to monitoring blood oxygen levels because it is affordable, convenient, and easy to use.

Tabletop Pulse Oximeter
The tabletop pulse oximeter is bigger as compared to a handheld pulse oximeter. It can perform on-the-spot readings and continuous oxygen saturation monitoring. This kind of pulse oximeter is ideal in hospitals and subacute settings.
Wrist Pulse Oximeter
This pulse oximeter is a wireless model usually preferred for continuous monitoring of a patient’s blood oxygen saturation. It is for patients in need of monitoring on a daily bases or during their sleep. The wrist pulse oximeter is worn on the wrist like a wristwatch. It has a probe placed on the index finger, which connects to a small monitor on the wrist. If you are looking for wrist pulse oximeters, click here for the best options available.
Fetal Pulse Oximeter
The fetal pulse oximeter can fit snuggly on a neonate’s small fingers. In case the infant’s fingers are too small to fit the probe, there are other varieties designed to fit the head or foot. This pulse oximeter is specifically for children.
Pulse Oximetry Approach
Pulse oximetry can be used in inpatient, outpatient, and even for home use when recommended by a health physician. It can be done by the following approach:
Another approach would be through the ears. For this, the transmission probe is clipped on the patient’s earlobe, wherein it connects into the monitoring unit that displays the oxygen saturation level.
It is the most common method of acquiring a patient’s pulse oximetry. The probe should be well-positioned on the finger of the patient making sure that the device is n too tight or too loose. The patient will feel a small amount of pressure, but there is no pain involved during the procedure.
Foot or Palm Approach
For neonates, their fingers or ears may still be too small to place the clip. For this situation, the pulse oximeter probe can be attached over the infant’s foot or palm.
In rare cases wherein the fingers and ears are inaccessible, a pulse oximetry reflectance probe may be attached low across the forehead and just right above the eyebrows of the patient. Place it away from a major vessel. For this approach, the patient should be in an inclined position. A headband is then strapped across the forehead over the probe to keep it in place.
Are There Any Limitations?
Pulse oximetry is an accurate test that provides results within only a 2-percent difference from the actual reading. On the other hand, some factors can impact accuracy. Below are the limitations of pulse oximetry according to Cables and Sensors.
Placing the probe on a finger with any polish or pigment can interfere with the readings. It is because the color can absorb the emitted light, which makes it unable to detect oxygenated hemoglobin. Before putting on the probe to the patient’s fingers, make sure that they remove the nail polish. In case it is not possible to remove the polish from the finger before the test, the probe can be turned sideways, or you can find another possible site to place the probe.
Exposure to Direct Bright Light
Another factor that can affect the reading of a pulse oximeter includes having a direct bright light shining at the probe like sunlight or operating light. While the device has a soft rubber that shields it from the light, it may not be able to avoid bright light shining directly on the device. See to it that you perform the procedure in a room with adequate lighting.
The movement of the patient can also lead to an inaccurate reading. It is because the probe can easily dislodge. If the patient is fussy or shivering, you might want to hold the hand to keep it steady, or you can also wait until the shaking has dispersed before resuming the test.
