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