McKesson Fingertip Pulse Oximeter

Finger Pulse Oximeter Pulse Rate, Pulse Bar and Plethysmogram   The McKesson finger pulse oximeter is a portable, non-invasive unit used to measure blood oxygen saturation and pulse rate. The adjustable brightness OLED displays SpO2 (Oxygen Saturation), pulse rate, pulse bar and plethysmogram in easy-to-read font and format. It also features six display modes with options that allow users to toggle in all four directions and options to show plethysmogram or pulse bar. Designed for low-power consumption, it automatically powers off when it's not in use to extend battery life and provide longer usage. It doesn't require routine calibration or maintenance; simply replace the batteries as necessary. Plethysmogram in finger pulse oximeters measures changes in volumetric variation of the finger due to pulsatile flow of blood in ulnar artery, to obtain the arterial pulse waveform of the subject.   Features: Non-invasive spot-check measurement of functional blood oxygen saturation and pulse r
