Innovo Fingertip Pulse Oximeter with Plethysmograph & Perfusion Index, Deluxe Ivory White (Made Exclusively for Amazon.com);

The Innovo Deluxe Fingertip pulse oximeter shows your measured SpO2 and Pulse Rate on a high quality OLED screen (with six multidirectional display choices) and come with two critically acclaimed features, the Plethysmograph and Perfusion Index (PI), that will improve the reliability of the readings dramatically. Each wave corresponds to a heartbeat and the amplitude to the amount of blood detected in your blood vessels. When the height of the wave amplitude no longer fluctuates (as shown like the figure above), this means that the pulse oximeter is now optimized and you may now take the readings. Meanwhile, the 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 too cold or improperly positioned in the pulse oximeter. Simply warm your finger and reposition it so that it is right under the LED lights. No more second guessing if the readings are reliable or why the pulse oximeter is not giving a reading. Using a vastly improved sensor, the Innovo deluxe pulse oximeter can also now correct for small movements, allowing more versatile usage. Comes with a lanyard and 2 AAA batteries so that you can use the pulse oximeter right out of the box. Please note that this is not a medical device. This pulse oximeter should be used only for sports and/or aviation. Intended use for spot check of blood oxygen saturation level at home, in sport and recreational use, such as mountain climbing, high-altitude activities and running. The oximeter might not work on kids or adults with small fingers. Innovo is a registered trademark of USPTO.
