Smart Wrist Pulse Oximeter User Manual
1. Introduction
1.1 Intended Use This product is intended to be used for measuring, displaying and storing of pulse oxygen level (SpO2)  heart rate and motion of adults. App can show the oxygen level, heart rate; get record, display results and report. It's not a medical device. This device is for Sports and Aviation use only and not intended for medical use. Note:
The data and results provided by this device are for pre-check screening purpose only and cannot be directly used for diagnostic or treatment. The data provided by the APP and PC software (optional) is not intended for diagnosis or treatment purpose, always consult your doctor for any health condition.
Warnings and Cautionary Advices · DO NOT squeeze the sensor or apply excessive force on
the sensor & cable.
 Do not use this device during MRI examination.  Never submerge the device in water or other liquids. Do not
clean the device with acetone or other volatile solutions.  Do not place this device in pressure vessels or gas
sterilization device.  Consult your doctor immediately if you experience
symptoms that could indicate acute disease.  Do not self-diagnose or self-medicate on the basis of this
device without consulting your doctor. In particular, do not start taking any new medication or change the type and/or dosage of any existing medication without prior approval.  Use only cables, sensors and other accessories specified in this manual.  Prolonged using may increase the risk of undesirable changes in skin characteristics, such as irritation, reddening, blistering or burns.  Check the oxygen level sensor application site every 6-8 hours to determine the positioning of the sensor and the circulation and skin sensitivity of the user. User sensitivity varies depending on personal status or skin condition. For users with poor peripheral blood circulation or sensitive skin, inspect the sensor site more frequently.  Functional tester cannot be used to assess the accuracy of an oxygen level sensor or a device.  This device is designed to determine the arterial oxygen saturation percentage of functional hemoglobin. Factors that may degrade pulse oximeter performance or affect the accuracy of the measurement include the following:
- excess ambient light
- excessive motion - electrosurgical interference - blood flow restrictors
(arterial catheters, blood pressure cuffs, infusion lines, etc.) - moisture in the sensor - improperly applied sensor - incorrect sensor type - poor pulse quality - venous pulsations - anemia or low hemoglobin -concentrations - cardiogreen and other -intravascular dyes - carboxyhemoglobin - methemoglobin - dysfunctional hemoglobi
