FingertipPulse OximeterUSER MANUALVer2.0C208General DescriptionOxygen Saturation is a percentage of Oxyhemoglobin (HbO2) capacity, compounded with oxygen, by all combinative hemoglobin(Hb) capacity in blood. In other words, it is consistency of Oxyhemoglobin in blood. It is a very important parameter for theRespiratory Circulation System. Many respiratory diseases can result in oxygen saturation being lowered in human blood.Additionally, the following factors can reduce oxygen saturation: Automatic regulation of organ dysfunction caused by Anesthesia,Intensive Postoperative Trauma, injuries caused by some medical examinations. That situation might result in light-headedness,asthenia, and vomiting. Therefore, it is very important to know the oxygen saturation of a patient so that doctors can find problemsin a timely manner.The fingertip pulse oximeter features low power consumption, convenient operation and portability. Place one fingertip into thephotoelectric sensor for diagnosis and the pulse rate and oxygen saturation will appear on the display. It has been proven in clinicalexperiments that it also features high precision and repeatability.Measurement PrinciplePrinciple of the oximeter is as follows: A mathematical formula is established making use of Lambert Beer Law according toSpectrum Absorption Characteristics of Reductive hemoglobin (RHb) and Oxyhemoglobin (HbO2) in red and near-infrared zones.Operation principle of the instrument: Photoelectric Oxyhemoglobin Inspection Technology is adopted in accordance with CapacityPulse Scanning and Recording Technology, so that two beams of different wavelength of lights (660nm red and 940nm nearinfrared light) can be focused onto a human nail tip through a clamping finger-type sensor. A measured signal obtained by aphotosensitive element, will be shown on the oximeter’s display through process in electronic circuits and microprocessor shown onthe oximeter’s display through electronic circuits and a microprocessor.Diagram of Operation Principle1.
