What is a fingertip pulse oximeter?


Blood Oxygen Saturation (SpO2)

Your SpO2 reading is an estimation of the amount of oxygen in your blood. An SpO2 reading of 95% or greater is generally considered to be a normal oxygen level. However, an SpO2 reading of 92% or less (at sea level) suggests that your blood is poorly saturated. Insufficient saturation can cause a range of adverse health conditions—including chest pain, shortness of breath and increased heart rate.

Pulse Rate

Your pulse rate is an estimation of the number of times your heart contracts per minute. According to the Mayo Clinic, normal pulse rate values for adults range from 60 to 100 beats per minute (bpm). In general, 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, also known as bradycardia. Bradycardia can cause a number of problematic symptoms—including fainting, fatigue, chest pains and memory problems.

A pulse oximeter gives you accurate insights on your SpO2 and pulse rate within a matter of seconds, empowering you to respond quickly and confidently to abnormal readings. As a result, many people with adverse heart and breathing conditions invest in personal oximeters for in-home use.

Note: SpO2 and pulse rate measurements outside the normal range aren’t always a sign of health problems. For example, your heart rate can be expected to increase during exercise, and oxygen saturation may decrease slightly (it should still remain at 90% or greater).


For people with COPD, asthma or other lung diseases who want to stay active, the quality of their pulse oximeter is incredibly important. Fast, reliable oximeter readings play an essential role in helping patients adjust their oxygen flow when exercising, participating in social activities or spending time at home. High-quality monitoring devices can also help physicians with monitoring the efficacy of treatment efforts and respond quickly if the condition worsens. That’s why people spanning the globe count on a finger pulse oximeters for personal use.
