1. Introduction
1.1 Intended Use
This product is intended to be used for measuring,
displaying and storing of pulse oxygen saturation
(SpO2)，pulse rate and motion in home or healthcare
facilities environment. App can show real-time SpO2,
pulse rate; get record, display results and report.
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

2
in this manual.
Prolonged continuous SpO2monitoring may increase the
risk of undesirable changes in skin characteristics, such as
irritation, reddening, blistering or burns.
Check the SpO2sensor application site every 6-8 hours to
determine the positioning of the sensor and the circulation
and skin sensitivity of the patient. Patient sensitivity varies
depending on medical status or skin condition. For patients
with poor peripheral blood circulation or sensitive skin,
inspect the sensor site more frequently.
Functional tester cannot be used to assess the accuracy of
a SpO2sensor 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 hemoglobin

Measurement accuracy verification: The SpO2accuracy has
been verified in human experiments by comparing with arterial
blood sample reference measured with a CO-oximeter. The
pulse rate accuracy has been verified by Emulator. Pulse
oximeter measurement are statistically distributed and about
two-thirds of the measurements are expected to come within
the specified accuracy range compared to CO-oximeter
measurements.
