Chapter 3 Operation Preparations
3.1 Preparing the Patient
3.1.1 Instructing the Patient
Before attaching the electrodes, greet the patient and explain the procedure. It can
decrease the patient's anxiety. Reassure the patient that the operation is painless.
Privacy is critical for the patient to relax. When possible, prepare the patient in a quiet
room or area where others can't see the patient. Make sure that the patient is comfortable.
The more relaxed the patient is, the less the ECG will be affected by muscle noise.
3.1.2 Cleaning the Skin
Thorough skin preparation is critical. The skin is a poor conductor of electricity and
frequently creates artifacts that distort the ECG signals. By performing systematic skin
preparation, you can significantly reduce the possibility of noise caused by muscle tremor
and baseline drift, ensuring high-quality ECG waves. There is natural resistance on the
skin surface due to dry, dead epidermis cells, oils, and dirt.
To Clean the Skin
1. Shave hair from electrode sites, if necessary. Excessive hair prevents a good
connection.
2. Wash the area thoroughly with soap and water.
3. Dry the skin with a gauze pad to increase capillary blood flow to the tissues and
remove the dead, dry skin cells and oils.
