3.1 Prior to Use
Before using ECG
Before using Daily Check or ECG Recorder function, pay attention to the following points
in order to obtain precise measurements.
If your skin or hands are dry, moisten them before taking the measurement.
During the measurement, do not touch your body with the hand with which you
are taking the measurement.
Please note that there must be no skin contact between your right and left hand.
Otherwise, the measurement cannot be taken correctly.
Stay still during the measurement, do not speak and move.
If possible, take the measurement when sitting instead of standing.
Before using Oximeter
Before using Daily Check and Oximeter function, pay attention to the following points in
order to obtain precise measurements.
The finger inserted in SpO2 sensor must be clean.
Any of the following conditions may cause inaccurate measurements, including
but not limited to:
-
Flickering or very bright light;
-
Poor blood circulation;
-
Low hemoglobin;
-
Hypotension, severe vasoconstriction, severe anemia or hypothermia;
-
Nail polish, artificial nails;
-
Any tests recently performed on you that required an injection of
intravascular dyes.
The Oximeter may not work if you have poor circulation. Rub your finger to
increase circulation, or place the SpO2 sensor on another finger.
The Oximeter measures oxygen saturation of functional hemoglobin. High levels
of dysfunctional hemoglobin (caused by sickle cell anemia, carbon monoxide,
etc.) could affect the accuracy of the measurements.
The pleth waveform displayed on the device is normalized.
Warnings and Cautionary Advices
Limit finger movement as much as possible when using the Daily Check or
Oximeter, which might result in incorrect reading or analysis.
