The Best Pulse Oximeters for Use at Home

To keep yourself and your family healthy, use the best pulse oximeters to monitor your blood oxygen levels. In search of the best pulse oximeter? This guide will assist you in selecting the best one for you, as well as show you the best price available.

Home pulse oximeters are an excellent tool for monitoring your blood-oxygen levels, and they are now very affordable. You might be surprised that such a thing is even possible if your home medical kit consists of only sticking plasters and antiseptic. Many people, however, find it very desirable to use optical technology to monitor blood oxygen saturation (SpO2), a figure that can reveal illness even when the patient is unaware of it. Along with the infrared thermometer, this is something you should have in your medicine cabinet (opens in a new tab).

The SpO2 level in the blood should be 95-100 percent. Hypoxemia occurs when oxygen levels fall below 90%. A pulse oximeter functions similarly to a digital camera in that SpO2 can be detected optically by passing light from an emitter to a sensor located somewhere arterial blood flows (like the middle finger of the dominant hand). The more oxygenated the air, the fewer light frequencies pass through. For accurate results, the devices must also account for the distance traveled by the light as well as any ambient light.

Certain conditions necessitate regular monitoring, whereas athletes and pilots can all benefit from their own devices. In an era when acute respiratory diseases (SARS, Covid-19) are on the rise and test prices are rising, it is possible to detect a drop in lung capacity by taking regular readings; however, you can only assist your doctor, not replace them!

How do pulse oximeters function?

A pulse oximeter, also known as a “pulse ox,” is a device that measures heart rate and oxygen levels in the body. They are typically found in a hospital or clinical setting, but there are at-home or consumer electronic versions available online.

What exactly do pulse oximeters do?

“One can use a pulse oximeter at home to measure your oxygenation, or at a clinic (or at hospitals) to monitor how much a person is oxygenating, and if blood is saturated with oxygen,” says Julie Chen, MD, an internal medicine specialist in California.

Who should use pulse oximeters?

According to John Hill, RRT, of pulmonary services at Deborah Heart and Lung Center in New Jersey, those with chronic heart and respiratory conditions benefit the most from using a pulse oximeter.

“Patients with lung or heart conditions, such as those with chronic obstructive pulmonary disease [COPD] and asthmatics, as well as those with allergies, benefit from monitoring their oxygen levels,” Hill explains.

COVID-19, a respiratory-borne illness that affects oxygenation status, has recently increased the demand for pulse oximeters, according to Vicken Zeitjian, MD, a cardiovascular specialist at UT Health in San Antonio.

“COVID-19 is a respiratory-borne illness, and admission to the hospital is frequently based on oxygenation status,” Zeitjian explains. “While the virus may cause a variety of symptoms, and oxygen saturation of less than 90% should prompt someone to seek medical attention.”

What is the precision of pulse oximeter readings?

According to Chaim, most at-home pulse oximeters provide users with accurate readings. However, he cautions that the accuracy of pulse oximetry readings can be affected by a number of factors.

How do blood oxygen levels in pulse oximeters get measured?

Pulse oximeters work by shining a light through the finger (or earlobe) and then measuring the reflection of the light beam to see how much light passes through, or gets reflected away from the sensor on the other side,” says Brooklyn, New York-based physical therapist Chaim Backman, PT, EMT. The amount of oxygen in the blood is then calculated using a mathematical equation by oximeters.”

What is a healthy pulse oximeter reading?

According to Backman, a normal pulse oximeter reading falls between 98 and 99 percent.

Anything less than 90 percent indicates a more serious problem that must be addressed immediately, he adds.

What factors influence pulse oximeter readings?

For starters, nail polish color and decals, as well as acrylic or gel nails, can all have an effect on readings.

“If nail polish absorbs light at 660 nm [nanometers] or 940 nm of light, it can affect pulse oximeter readings,” Zeitjian explained. “This is most noticeable in black, green, and blue nail polish.” Keep in mind that artificial acrylic nails may impair the accuracy of pulse oximeter readings.”

Furthermore, Chen suggests that the following factors can influence reading accuracy:

  1. anemia
  2. low blood pressure
  3. skin with more pigment
  4. low body temperature
  5. intravascular dyes, which are used at a hospital for certain tests

“Dark skin and intravascular dyes in the blood make it difficult for the sensor to read oxygenation because the coloring makes it difficult to read,” Chen explains.

“Low blood pressure means less blood volume, and anemia means fewer blood cells, making it difficult for the sensor to see the data,” explains Chen. “Low body temperature also causes blood vessels to constrict, making it difficult to read.”

What kinds of pulse oximeters are there?

According to Jaydeep Tripathy, MBA-MPH, Ph.D., a board-certified internist, pulse oximetry probes or sensors can be attached to the finger, nose, ear, toes, and forehead.

He adds that the most accurate readings are usually obtained when the pulse ox is clamped to the finger, specifically the middle finger, rather than other body parts.

However, according to board-certified internal medicine specialist Spencer Kroll, MD, Ph.D., pulse oximeter probes frequently vary in a clinical setting.

Hospital-based pulse oximeters can be connected to equipment that simultaneously measures a patient’s heart rhythm and machines that measure blood pressure and temperature, according to Kroll.

While hospital systems are able to provide a printout of readings, he continues, “home-based pulse oximeters only measure the pulse oxygenation and the heart rate.” However, some smartphone-compatible pulse oximeter accessories are now available that can save data for later printing.

How to Make a Decision

There are numerous brands to choose from when shopping for at-home pulse oximeters, according to Zeitjian.

“When purchasing, look for pulse oximeters labeled ‘for medical use’ and ‘FDA approved,'” Zeitjian advises. “These can be found on products sold at CVS, Walgreens, and Target. Most pulse oximeters also measure your heart rate, which many people appreciate.”
