All rights reserved.1 OverviewThe pulse oxygen saturation is the percentage of HbO2 in the total Hb in the blood, so-called the O2concentration in the blood. It is an important bio-parameter for the respiration.Many respiratory diseases will cause the body’s SpO2 to decrease, while the body automatic adjustmentdisorder caused by the anesthesia, big surgery trauma, and some of the damage caused by medicalexamination, are likely to lead to patient’s oxygen supply problems and reduce the body’s SpO2, resultingin patient dizziness, weakness, vomiting and other symptoms. Severe cases will threaten life. So knowingthe patient’s SpO2 in time will help doctor which has great significance in clinical medical area.The Pulse Oximeter features a small size, low power consumption, convenient operation, and portability.It is only necessary for patient to put one of his fingers into a fingertip photoelectric sensor for diagnosis. Adisplay screen will directly show measured value of Hemoglobin Saturation.1.1 Features Simple and convenient operation. The product is small in size, light in weight, and convenient to carry. Low power consumption.1.2 Major Applications and Scope of ApplicationThe product is applicable for use in family, hospital, oxygen bar, community medical treatment and sporthealth care (it is advised to be used before and after sports and it is not suggested to be used in theprocess of sport),etc.The product is not suitable for use in continuous supervision for patients.The problem of overrating would emerge when the patient is suffering from toxicosis which iscaused by carbon monoxide. The device is not recommended to be used under thiscircumstance.1.3 Environment RequirementsStorage Environmenta) Temperature: -40ºC~+60ºCb) Relative humidity: ≤95%c) Atmospheric pressure: 500hPa~1060hPaOperating Environmenta) Temperature: 10ºC~40ºCb) Relative Humidity: ≤75%c) Atmospheric pressure: 700hPa~1060hPa1.4 Safety1.4.1 Instructions for Safe Operations Check the main unit and all accessories periodically to make sure that there is no visible damagethat may affect patient’s safety and monitoring performance.

DO NOT operate keys on front panel with sharp materials. High temperature or high pressure steam disinfection of the oximeter is not permitted. Refer to UserManual in the relative Chapter for instructions of cleaning and disinfection. Do not have the oximeter immerged in liquid. When it needs cleaning, please wipe its surface withmedical alcohol by soft material. Do not spray any liquid on the device directly. When cleaning the device with water, the temperature should be lower than 60ºC. As to the fingers which are too thin or too cold, it would probably affect the normal measure of thepatients’ SpO2 and pulse rate. Please clip the thick finger such as thumb and middle finger deeplyenough into the probe. Do not use the device on infants or neonatal patients. The product is suitable for children above four years old and adults (Weight should be between 15kgto 110kg). The device may not work for all patients. If you are unable to achieve stable readings, please stopusing. The update period of data is less than 5 seconds, which is changeable according to differentindividual pulse rate. The waveform is normalized. Please read the measured value when the waveform on screen isequably and steady-going. Here this measured value is the optimal value. And the waveform at themoment is the standard one. If some abnormal conditions appear on the screen during test process, pull out the finger andreinsert to restore normal use. The device has normal life span of three years since the first electrified use. The hanging rope attached the product is made from Non-allergy material. If a particular group issensitive to the hanging rope, stop using it. In addition, pay attention to the use of the hanging rope.Do not wear it around the neck to avoid causing harm to the patient.
