The Dr. Morepen Pulse Oximeter (Model PO-12A) is designed for fingertip measurements of blood oxygen saturation degrees (SpO2) and pulse rate. The tool is meant to be used through sufferers and healthcare specialists as an resource withinside the control of continual respiration illnesses or the control of circulatory machine illnesses. The tool isn't always designed to diagnose or check for respiration or circulatory machine problems. Device Description: The Dr. Morepen Pulse Oximeter is a small and transportable tool for the size of blood-oxygen saturation degrees. The affected person can degree his or her blood-oxygen saturation degrees through surely setting one finger into the Fingertip Photoelectric sensor. Principle of Operation Light emitting diodes in the SpO2 sensor radiate pink and infrared mild via the tissue. The majority of sensors function on extremities which include a finger, toe, or ear. Much of the mild is absorbed through the blood, tissue, and bone on the utility site. Some mild does, however, get via the extremities. It is detected through a mild-touchy detector placed contrary the mild source. The amount of mild detected through the detector describes the quantity of oxygen connected to haemoglobin withinside the blood. Oxygenated haemoglobin (oxy-haemoglobin or HbO2) absorbs greater infrared mild than pink mild. Deoxygenated haemoglobin (Hb) absorbs greater pink mild than infrared mild. The SpO2 size is calculated through evaluating the portions of pink and infrared mild received. Features: Dual coloration OLED display With AAA batteries, it could run constantly for greater than six hours and consumes little power. Auto Power Off – Automatically turns off after the finger is removed Wave from Display Pulse Rate (PR) Display Small in volume, lightweight, and smooth to transport Low battery indicator Package Content: One User manual Dr. Morepen Pulse Oximeter 2xAAA Alkaline Batteries Specifications Value Display type OLED display SpO2 Measurement range: 70%~99%; +/-2% Accuracy of SpO2 Measurements: 80%~99%; +/-2% 70%~79%; +/-3% Below 70%: Undefined; Resolution of SpO2 Measurement 1% Dimension 58mmx 36mm x 33mm
