Using Checkme
Prior to Use Before using ECG
Before using Daily Check or ECG Recorder function, pay attention to thefollowingpointsin 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 youare 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 ofstanding.
Before using Oximeter
Before using Daily Check and Oximeter function, pay attention to the followingpointsin 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.
