Batteries not included. Why Keep a Check on Your Blood Oxygen Sp02 Levels? ⁍If the organs don’t receive enough oxygen, they cannot work effectively. Likewise, muscles can’t function without enough oxygen which devalues your exercise session. ⁍Low blood oxygen levels can lead to fatigue, lack of energy and even dizziness, which is not good when you’re trying to build up your strength and stamina through exercise. Perfusion Index： The Perfusion Index (PI) conveniently informs you of the strength of your pulse. If the PI value is less than 0.2%, this means that your hands are either too cold or improperly positioned in the pulse oximeter. Simply warm your finger and reposition it so that it is right between the LED light and sensor.
