What is a pulse oximeter, and why use it?

A pulse oximeter is a small, non-invasive device whose function is to measure the person’s heart rate and oxygen level in the blood. It is designed to quickly detect fluctuations in blood oxygen levels.

The device is useful because it can forewarn the user about low oxygen saturation, which may occur if the person has certain health conditions, such as lung or heart disease. It also helps to see if, for example, oxygen therapy is effective.

The pulse oximeter is commonly used by medical professionals in clinics and hospitals, however, it can also be used by non-medics at home.

To read one’s pulse and oxygen level, the pulse oximeter needs to be attached to a body part, usually to a finger and kept for a certain amount of time. The readings are displayed on the device’s screen.

Benefits of using a pulse oximeter

Non-invasive and simple to use, the pulse oximeter allows you to monitor your health state at home and may safe an unnecessary trip to the doctor or give a warning when you may need medical attention. Here are some of the benefits of the device:

Helps to make sure you’re exercising safely

Sometimes healthcare professionals use pulse oximeters and similar devices to make sure physical activity is safe for people who have cardiovascular or respiratory issues, e.g. chronic obstructive pulmonary disease (COPD).

Even if your condition is not grave and moderate exercise is considered safe for you, you may want to monitor your pulse and oxygen level just to be on the safe side. In this case, wearing a pulse oximeter while exercising may be a good idea. According to the device’s readings, you can adjust the intensity of your workout regime.

Alerts when oxygen level drops too low

There may be various reasons why a person’s blood oxygen level fluctuates, e.g., chronic cardiovascular or respiratory conditions, acute pulmonary infections such as pneumonia, prescription drugs that affect oxygen saturation and obstructive sleep apnea.

In all these cases, a device that can be used at home and warn the person about a severe dip in the blood oxygen level is useful as it helps prevent more serious health issues. It can also appease people with dangerous health conditions as they have a handy device that allows them to keep tabs on their pulse and oxygen saturation regularly.

Allows older adults to monitor their oxygen levels

As we get older, our body’s ability to intake oxygen and use it optimally may decrease as people tend to have more chronic respiratory and heart health conditions with age. This is why some older adults may have lower blood oxygen levels.

Regular use of a pulse oximeter is a relatively simple way to monitor one's heart rate and blood oxygenation at home, even if the condition is not grave. It can bring peace of mind to older people who worry about their health or simply want to keep tabs on their body vitals as instructed by a healthcare provider.

How to use a pulse oximeter effectively

  • Settle down comfortably and rest for a few minutes. If you are stressed or agitated, please make sure you calm down first.
  • If you are going to place the device on your finger.
  • Make sure your hand or any other body part you will use for measuring is warm, dry and the muscles are relaxed.
  • Place the oximeter on your finger. The device should feel tight enough to maintain steady contact but not squeezing or painful.
  • Stay still until the numbers are steady.
  • Record the numbers displayed: they indicate your heart rate and your blood oxygen level.
  • Remove the device and store it as recommended.

Common mistakes to avoid when using a pulse oximeter

When used correctly, oximeters are generally accurate. If you have a reason to believe your oximeter results are faulty, you may not be using it correctly. Here are some of the most common factors that affect the results:

  • Incorrectly positioned finger. The device should fit the finger snugly. When too tight, it may restrict blood circulation. When too loose, it may slide off or allow outside factors, such as light, to interfere with the reading.
  • Fingernail varnish or artificial nails. Nail varnish or dirt on the nail can absorb the light that comes out from the pulse oximeter and the test might be slightly less accurate.
  • Hand movement during the reading. Movement of the hand or movement of the device can lead to measurement inaccuracies. Keep the hand still and do not fiddle with the oximeter.
  • Skin temperature. Cold hands mean that the blood circulation in your hand is low and the oximeter may not detect a good pulse signal.

If you want to make sure your oximeter lasts its maximum lifespan and functions optimally, follow the manufacturer's instructions. Check the user’s guide, as maintenance recommendations for your current device may differ from the previous one. Here’s what we recommend:

Pulse oximeter care and maitenance

To ensure your oximeter lasts its maximum lifespan and functions optimally, follow the manufacturer's instructions. Check the device's user guide, as maintenance recommendations for your current oximeter may differ from the previous one. Here’s what we recommend:

  • Keep it clean. This prevents possible accumulation of any foreign organisms or debris.
  • Store in a safe place. Protect your oximeter from dust, dirt, corrosive substances, liquids, and explosives. Make sure the device is kept dry and at room temperature.
  • Change batteries when needed. Do so when the symbol indicating that the battery needs to be replaced appears on the display.
  • Check the warranty period. Generally, if your oximeter has passed its warranty it may be time to replace the device. Check the manufacturer’s instructions for replacement guidance.

Best pulse oximeter — conclusion

When used correctly, this device can be handy for those who like to keep an eye on their vitals. From alerting you about dangerously low oxygen levels to helping adjust the exercise intensity for people who have chronic diseases, it’s a convenient way to take better care of your well-being.

To make sure the oximeter serves you well, please read the user guide and follow the manufacturer’s recommendations. If used correctly and well-maintained the device can be a helpful tool for monitoring your and your family members' health at home on a daily basis.
