SpO2 Finger Pulse Oximeter Your body needs oxygen to live life to the fullest. Your red blood cells have the vital task of delivering oxygen to every cell inside the body. With the help of hemoglobin (Hb), the red blood cells carry oxygen throughout the body. With iProven's Blood Oxygen Meter Finger you can measure how much oxygen your blood carries. On the screen, this number will show in percentages. A healthy person with healthy lungs, breathing air at sea level, will have an oxygen level of between 95% and 100%. Pulse Rate and Perfusion Index Next to measuring SpO2, the iProven Oxygen Monitor also measures your pulse rate in beats per minute. In rest, your pulse rate will be somewhere around 60 to 80 BPM, depending on your cardiovascular condition. This is the only unique Oximeter to offer respiratory rate! Respiratory Rate or RR is the number of breaths you take per minute. This premium functionality of the Oxygen Saturation Monitor is especially helpful to people who use breathing exercises to relax.
