How to Choose the Best Pulse Oximeter for Nurses and Respiratory Therapists

In this guide, you will learn what a pulse oximeter is, how they work, and why you would need to use one. You’ll also discover the many important features that you need to look for in a pulse oximeter such as accuracy and perfusion index measuring. Let’s get started.

What is a Pulse Oximeter?

A pulse oximeter is a small, non-invasive, lightweight, electronic device that instantly measures the amount of oxygen in the blood, also known as SpO2 A pulse oximeter also records your current pulse rate (PR), meaning the number of times your heart beats per minute.

Pulse oximetry can help people with respiratory or cardiovascular conditions to monitor their health and respond quickly if there is a health problem.

Pulse Oximeter Types

There are two common types of pulse oximeters:

  1. Medical Grade
  2. Recreation and Home Use

Medical grade pulse oximeters are used by nurses, respiratory therapists, and healthcare workers in a clinical setting. Theses types of pulse oximeters can only be purchased from medical supply manufacturers by medical professionals.

Recreational and home use pulse oximeters are for monitoring your health at home or during a recreational activity, such as working out at the gym or hiking at altitude.

These types of oximeters can be used on your fingertips, wrists, or be handheld.

How Does a Pulse Oximeter Work?

Pulse oximeters clip painlessly to a finger, toe, or earlobe. When it is activated, the device releases light from one side, then the light is received by a sensor on the other side of the pulse oximeter.

Because oxygen and hemoglobin absorb light, the amount of light that makes it to the sensor can tell you the proportion of these molecules that exist in the blood. A pulse oximeter determines approximately how many hemoglobin cells are in the blood that moves through the artery closest to the device’s location. It also discerns how many of those cells are bonded with an oxygen molecule.

Once the pulse oximeter completes the measurements, its screen will display your blood oxygen saturation, or SpO2, and your pulse rate.

Which Finger is Best For Pulse Oximeter Readings?

A pulse oximetry study from the National Center for Biotechnology Information and U.S. National Library of Medicine found that using the right middle finger and right thumb gives the most accurate blood oxygen saturation levels and pulse rate when using a finger pulse oximeter.

Why Are Blood Oxygen Levels And Pulse Rates Important?

The body needs oxygen to survive. Without enough of it in the bloodstream, the body won’t function optimally, and you might experience health problems.

A healthy individual’s SpO2 should be 95 percent or greater. If it’s 92 percent or lower, the blood is not well-saturated with oxygen and can cause what is called hypoxemia.

Some symptoms of hypoxemia include:

  • Headaches
  • Shortness of breath/trouble breathing
  • Rapid heartbeat
  • Coughing
  • Wheezing
  • Disorientation
  • Blue fingernails, skin or lips

Your pulse rate is an estimation of the number of times your heart contracts per minute.

A normal resting pulse for an adult is 60 to 100 beats per minute or bpm. Usually, a lower heart rate indicates that someone is healthier because the heart doesn’t need to contract as frequently to circulate the blood. People with lower heart rates tend to have better cardiovascular fitness and heart function.

For most people, a pulse rate that’s lower than 60 bpm is abnormally slow. This is referred to as bradycardia, and it can cause breathing and memory problems. People with bradycardia may also have fainting spells.

Why Would You Need to Use a Pulse Oximeter?

People with heart or breathing problems can use a pulse oximeter at home to stay on top of their health. Pulse oximeters help patients manage certain conditions with guidance from medical professionals. There are several benefits to using a pulse oximeter.

Managing COPD. People with chronic obstructive pulmonary disease, or COPD, are usually advised to carry finger pulse oximeters at all times. This disease occurs when the lungs are so damaged that the body can’t heal them. Managing the illness involves using a medication, making lifestyle changes, and monitoring their oxygen saturation.

Many people with COPD need to know exactly how much oxygen to titrate to meet their needs. Using a good pulse oximeter can help predict when symptoms will worsen and allow patients and doctors to accurately adjust their oxygen usage.

Asthma Care. Individuals who suffer from asthma may experience issues with their oxygen levels. Asthma attacks can make it hard to breathe. Detecting fluctuations in SpO2 with a pulse oximeter may be able to predict attacks before they become serious. These patients can then use a rescue inhaler before the attack happens, delivering more effective treatment.

Side Effects from Medications. Some medications, such as opioids, can slow down your breathing to dangerous levels. If you’re taking a drug that has respiratory side effects, you may want to use a pulse oximeter to check your SpO2 levels periodically. A healthcare professional can use them to monitor oxygen saturation when patients are under anesthesia.

Monitoring Your Fitness. The body has trouble maintaining oxygen saturation when you work out, especially if you’re not in great shape. If you have ever pushed yourself to the point of exhaustion while exercising, your oxygen saturation may have plummeted without you knowing it.

For example, endurance athletes bring along a sports use pulse oximeter to make sure that they’re getting consistent oxygen flow throughout the duration of their workout. For many athletes, maximizing efficiency is important. Keeping your oxygen level at the optimal range can improve your performance when you’re exercising. If oxygen saturation levels fluctuate, you can make real-time adjustments, such as doing breathing techniques.

Being in High Altitudes. If you’re planning on taking a hike through the mountains or regularly work out at high altitudes, a good pulse oximeter can help prevent you from experiencing oxygen deprivation issues. Pulse oximetry can predict acute mountain sickness, also known as altitude sickness.

Most instances of altitude sickness are mild, but they can occur when you are 8,000 feet above sea level. Symptoms of acute mountain sickness include dizziness, nausea, and shortness of breath. The condition is more likely to occur when an individual is suffering from hypoxia.

Infants and Newborns. Pulse oximeters are often used in neonatal units to assess respiratory health in infants, especially newborns. Some manufacturers are marketing devices for parents who want to monitor their babies’ breathing overnight. Although doing so may give parents peace of mind, there are no studies indicating that using a pulse oximeter prevents sudden infant death syndrome or SIDS.

Sleep Apnea. This is a disorder that causes interrupted breathing during periods of sleep. It can be caused by physical obstruction, such as the collapse of soft tissues in the airways. However, sometimes, the brain doesn’t send the right signals that tell your body to breathe while you sleep. People with this condition can develop low oxygen levels overnight.

Using a pulse oximeter can help you detect whether your SpO2 levels drop overnight.

Features to Look for in the Best Pulse Oximeters

It can be hard to determine the best pulse oximeters to buy because there are so many in the marketplace. Look for the following characteristics in the pulse oximeter that you decide to purchase.

Accuracy. Many brands guarantee that their pulse oximeter is accurate. Look for accuracy guarantees that fall within ±2 percent of actual blood oxygen saturation levels. The best oximeters should also be accurate to approximately 70 or 80 percent SpO2. If it’s not, it won’t give you the best reading when your oxygen saturation is extremely low.

Some pulse oximeters give you a visual representation of your heartbeat in a plethysmograph waveform. This signal can show that you have an arrhythmia. It can also be weak if the oximeter isn’t working properly.

If you receive an abnormal reading, you might want to clean off the sensors or reposition the pulse oximeter. Then, take another reading.

Pro Tip: Accuracy can be affected by edema, cold extremities, movement, and certain nail polish colors.

Perfusion Index Measurements. The best pulse oximeters measure your perfusion index or PI. This is the ratio of the pulsating blood to the static blood flow in your peripheral tissue like your finger, toes, or ear lobes. It is an indication of how strong your pulse is at the sensor site.

Everyone’s normal PI is variable. If a pulse oximeter includes this measurement, it can help you get a proper assessment of your baseline health so that you can be aware when the reading is off.

Alerts and Warnings. The pulse oximeter should alert you when there is an abnormal reading. You need to know when your heartbeat isn’t steady. An irregular heartbeat indicates that you have an arrhythmia and could be cause for concern.

You should also get a warning when your SpO2 levels are low. Many devices beep or buzz to indicate abnormal levels of oxygen saturation. An audible warning can help if you’re using the device at night or unable to see the display for any reason.

A low battery warning will also help you ensure that the pulse oximeter is working optimally. It’s especially important if you use the pulse oximeter regularly or rely on it to manage a health condition.

Size and Portability. Many people who use pulse oximeters need to carry them at all times. Therefore, the device needs to be portable and small enough to wear around your neck or in your pocket. Some people choose to wear them on a belt holster or stash them in their purse.

Weight. Although many good pulse oximeters are small and portable, some are heavy, making them uncomfortable to use. If you’re already weak because you have respiratory issues, you might have trouble using a heavy device. Athletes might also prefer a lightweight oximeter so that they can wear it at the gym or while running.

Heavy pulse oximeters are more likely to be dropped. They’re also more prone to damage if they fall to the floor.

Durability. If you require constant blood oxygen monitoring, you need a good pulse oximeter that stands up to regular usage. Look for one that can withstand accidental drops or mishandling.

A water-resistant product is also beneficial because humidity can affect the readings.

Fit. Some pulse oximeters are adjustable. These come in handy if you have particularly large or small fingers. A standard unit that’s designed for adults may not fit a child. If it doesn’t fit properly, it won’t deliver an accurate reading.

Look for a device that’s designed for your size. Children will usually get the most precise readings when using an oximeter that’s designed for them.

Easy-to-Read Display. You might want to consider buying a pulse oximeter with a backlit display. These come in a variety of colors and styles. The one that you choose comes down to personal preference.

A pulse oximeter with adjustable brightness settings is ideal if you’ll be using it in different lighting conditions. One that offers multiple viewing angles is easy to read and can prevent you from straining to see it. A multi-directional screen can also allow you to switch the view to show the results to a caregiver.

Recording Capabilities. Some pulse oximeters have recording capabilities via wired or wireless technology to access your data history of SpO2 levels and heart rate.

It can be helpful for optimizing exercise performance, tracking sleep quality, or for your doctor if they need to monitor your levels for any reason.
