Good electrode-to-skin contact is important for a good ECG
signal, as the skin is a poor conductor of electricity. It is necessary
to deal with the skin properly before placing the electrodes. The
steps are shown as follows:
1. Select sites with intact skin, without impairment of any
kind.
2. Clip or shave hair from sites as necessary.
3. Gently abrade the skin to remove dead skin cells to
improve the conductivity of the electrode site.
4. Wash sites thoroughly with soap and water, leaving no
soap residue.( We do not recommend using ether or pure
alcohol, because this dries the skin and increases the
resistance.)
5. Dry skin thoroughly.
5.3.2 PlacingElectrode
1. Preparation before electrode placement
1) Skin preparation (refers to Chapter 5.3.1).
2) Check if the buttons on the electrodes are clean and free of
damage.
3) Place the electrodes on the body of patient. Before
attaching, smear some conducting cream on the electrodes
