for details.
14.3.13 Turning off the device
Follow the steps below to turn off the device:
1.
Confirm that the patient's ECG examination has been completed.
2.
Remove the electrodes from the patient.
3.
Press and hold the power button for about 5 seconds, the screen
displays the prompt message "Shutting down...", and then the device
shuts down.
Caution
Press and hold the power button for no less than 10 seconds to forcibly shut
down the device if it could not be shut down normally. However, this operation
may cause data loss or corruption, please proceed with caution.
14.4 Preparing the Patient
Correct operation is very important to get the best quality
ECG.
14.4.1 Preparing the Patient Skin
The patient's emotions and body conductivity can obviously
affect the quality of ECG. To properly preparing the patient,
follow the steps below:
1.
Ask the patient to lie down comfortably and be relaxed.
2.
Remove the clothing from the patient where the electrode was
placed.
3.
Clean the skin where the electrodes are placed with alcohol. Shave
hair from electrode sites, if necessary. Excessive hair prevents a good
connection.
14.4.2 Attaching Electrodes to the Patient
The quality of ECG waveform will be affected by the contact resistance
between the patient and the electrode. In order to get a high-quality ECG,
the skin-electrode resistance must be minimized when you attach
electrodes to patients.
