Portable finger pulse oximeter with determination of blood oxygen saturation and heart rate measurement. \ \ portable finger oximeter: \ \ the microlife oxy 200 pulse oximeter is a non-invasive portable device that checks the oxygen saturation of arterial hemoglobin (spo2) and heart rate. the oximeter is suitable for adults and children. it can be used for private use, as well as for use in the medical sector (hospitals, clinics). \ \ pulse oximetry technology uses the absorption of light by hemoglobin and the pulsatile mode of blood flow in the arteries. \ \ the pulse oximeter uses a sensor that shines light in two wavelengths, red and infrared, on a part of the body that is relatively thin and has good arterial pulsatile blood flow, usually the finger. It has a light detector which, together with a microprocessor, compares and calculates the differences between oxygen-rich and oxygen-poor hemoglobin. \ \ features: \ \ \ measurement of blood oxygen saturation (sp02%) and heart rate. \ display of measurements on an LED screen. \ automatic shutdown. \ spo2 measurement range: 35 – 100 %. \ pulse measurement range: 25 – 250 bpm. \ 2 x 1.5v (aaa) batteries included. \ weight 50gr (including batteries). \ carrying case. \ 2 year warranty. \ \
