Pulse Oximeter Yimi Life YM103 is a Blood Oxygen Saturation Monitor (SpO2) with Pulse Rate (PR) and Perfusion Index (PI). An oximeter is used for measuring the pulse oxygen saturation through the finger. Blood Oxygen Level Your body requires a very precise balance of oxygen in the blood. For your body to perform optimally, blood oxygen levels should be above 95%. Resting Heart Rate Heart beats per minute while at rest tells a lot about your internal health and fitness levels. It is a strong indicator of your risk for heart problems. Perfusion Index The normal perfusion index (PI) ranges from 0.02% to 20%. If the perfusion index is at or below 0.4% showing weak pulse strength, then the oximeter reading can be unreliable. Peripheral artery diseases, diabetes, obesity, blood clots, etc. are the reasons for poor perfusion.
