![]() Insufficient oxygen levels can result in several health problems like chest pain, increased heart rate, and shortness of breath. A SpO 2 of below 92% suggests that the blood is poorly saturated with oxygen. The normal reading of a healthy person should be 95% or higher. ![]() The level of blood oxygen saturation is usually expressed as a percentage. This property makes it possible to compare the relative intensities. One interesting fact about hemoglobin is that it reflects and absorbs light. The pigment can exist in the oxidized or reduced forms denoted as HbO 2 and Hb respectively.Īlso Read: How To Check Shutter Count Of Your Camera Pulse Oximeter Principle The measurement is done by assessing the oxygen-carrying pigment found in red blood cells – hemoglobin. Although these fluctuations are quite minute, they get can be measured by the pulse oximeter. As a result, there are changes in the amount of light such as red or infrared light that gets transmitted through the capillaries. The volume decreases between the heartbeats. During each contraction, blood gets squeezed into the capillaries slightly increasing their capacity. When the heart beats, it forces blood to be transported throughout the body. Normal heart rate ranges between 60 and 100 beats per minute for adults. The heart rate is defined as the estimated number of times that the heart contracts per minute. How do I go about selecting the right pulse oximeter ?.
