ECG

Patient preparation

The quality of the ECG reading is dependent on the degree of contact resistance between
the electrode and the skin. To ensure the lowest resistance consider the following
actions:
1. Shave the areas where the electrodes are to be placed.
2. Use alcohol to thoroughly clean the areas where the electrodes are to be placed.
3. When applying the electrodes, make sure that there is a layer of gel between the
electrode and the skin.

Note
WARNING In order to minimize interference and the danger of burns to the
patient, only use Welch Allyn ECG cables. Keep the ECG cable as far away as
possible from any electrosurgical cables. Make sure that the electrosurgical
return conductor (neutral) is properly attached to the patient and that good
contact is made.
To maintain the quality of signals during long-term monitoring, the electrodes
should be replaced at least every 48 hours. Over longer periods, the electrode gel
can dry out and the patient's skin can be irritated by the gel or adhesive. When
replacing electrodes, do not position the new electrodes on exactly the same
locations, but a little to the side of the original positions.
• When an electrode falls off or the resistance of an electrode is too high, a
lead-off indication is displayed and an audible alarm is issued.
• Color code: the colors shown here are according to IEC requirements. The
AHA color configuration is shown in
IEC/AHA" on page 43.
WARNING Patient harm. The monitor is type CF
approved Welch Allyn patient cables are used.
Caution Only use approved Welch Allyn patient cables. Use of other cables can
damage the monitor.
