Pulse Oximeter

HomeAid pulse oximeter 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.

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.

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).
