Oxygen finger monitor is a small, lightweight device used to monitor the amount of oxygen carried in the body. This noninvasive tool attaches painlessly to your fingertip, sending two wavelengths of light through the finger to measure your pulse rate and how much oxygen is in your system. Once the oximeter finishes its assessment, its screen will display the percent of oxygen in your blood coming from your heart as well as your current pulse rate.
How does it work?
When you insert your finger into an oxygen finger monitor, it beams different wavelengths of light through your finger. It’s targeting hemoglobin, a protein molecule in your blood that carries oxygen.
Hemoglobin absorbs different amounts and wavelengths of light depending on the level of oxygen it’s carrying. Your pulse oximeter will give you a numerical reading — a percentage that indicates the level of oxygen saturation in your blood. If you’ve been to a doctor in the past 20 years, you’ve experienced pulse oximetry.
The device works better with warmer hands than cold hands. And because oxygen levels can fluctuate, consider taking measurements a few times a day. Also try it in different positions, such as while lying flat on your back or while walking. Keep notes to share with your doctor if needed.
Why do you need an oxygen finger monitor
The purpose of an oxygen finger monitor is to check how well your heart is pumping oxygen through your body. It is also used to monitor the health of individuals with any type of condition that can affect blood oxygen levels, especially while they’re in the hospital. Below you can take a look at some of the conditions:
- chronic obstructive pulmonary disease (COPD)
- asthma
- pneumonia
- lung cancer
- anemia
- heart attack or heart failure
- congenital heart defects
There are a number of different common use cases for pulse oximetry, including:
- to assess how well a new lung medication is working
- to evaluate whether someone needs help breathing
- to evaluate how helpful a ventilator is
- to monitor oxygen levels during or after surgical procedures that require sedation
- to determine how effective supplemental oxygen therapy is, especially when treatment is new
- to assess someone’s ability to tolerate increased physical activity
- to evaluate whether someone momentarily stops breathing while sleeping — like in cases of sleep apnea — during a sleep study (source)
What is a good reading on an oxygen finger monitor
Oxygen finger monitor is typically a fairly accurate device. This is especially true when using high-quality equipment found in most medical offices or hospital settings.
Normal arterial oxygen is approximately 75 to 100 millimeters of mercury (mm Hg). Values under 60 mm Hg usually indicate the need for supplemental oxygen. Normal pulse oximeter readings usually range from 95 to 100 percent. Values under 90 percent are considered low. (source)
How do you read a finger oxygen monitor
How accurate are they?
The oxygen level from a pulse oximeter is reasonably accurate. Most oximeters give a reading 2% over or 2% under what your saturation would be if obtained by an arterial blood gas. For example, if your oxygen saturation reads 92% on the pulse oximeter, it may be actually anywhere from 90 to 94%.
Is it safe to use an oxygen finger monitor at home?
It’s possible that a home oxygen finger monitor could give a faulty reading or be used incorrectly, prompting a patient to seek care unnecessarily. If you or someone in your home shows a very low reading, you may want to test your device on a healthy person to confirm that it is working correctly and discuss it with your doctor.

The Metene® Pulse Oximeter Fingertip uses the most advanced photoelectric principle, through the high-quality transparent acrylic panel screen to let people directly judge whether the measuring environment is suitable for measurement, to avoid the influence of strong light on the measurement results, so as to ensure high accuracy.
- The normal range of oxygen saturation: SpO2 95%-99%.
- Insufficient oxygen supply: SpO2 90% – 95%;
- Mild hypoxemia: SpO 2 < 90%.
- Severe hypoxemia: SpO 2 < 85%.
