More than ever before, measuring the oxygen saturation level in your blood is vitally important as an early warning sign for those who may require urgent medical care. The Heart Sure Bluetooth Pulse Oximeter provides this quickly and accurately along with your pulse rate. The Heart Sure Bluetooth Pulse Oximeter measures your Oxygen Saturation (SpO2) & Pulse Rate quickly and conveniently via an index finger. With Bluetooth connectivity and the Jumper Health App, your oxygen saturation measurements can be recorded and graphed for future analysis by your healthcare professional. It is portable and ideal for taking measurements; pre/post-exercise and pre/post-operative conditions. The advanced algorithm can minimise the influence of motion and improve measurement accuracy of low perfusion. The low Perfusion index (PI) is an indication of the pulse strength at the sensor site of the SpO2 device on your finger. The Perfusion Index works from 0.2% for a very weak pulse and moves to a higher value for a stronger pulse.
