3.2 Preparing the Patient
3.2.1 Instructing the Patient
Before attaching the electrodes, greet the patient and explain the procedure. Explaining the
procedure decreases the patient’s anxiety. Reassure the patient that the procedure is painless.
Privacy is important for relaxation. 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 noise.
3.2.2 Cleaning the Skin
Thorough skin preparation is very important. The skin is a poor conductor of electricity and
frequently creates artifact that distorts the ECG signal. By performing methodical skin
preparation, you can greatly reduce the possibility of the 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 epidermal 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 to remove the
dead, dry skin cells and oils.
3.3 Connecting the Patient Cable to the
Electrocardiograph and Electrodes
WARNING
The performance and electric shock protection can be guaranteed only if original patient
cable and electrodes of the manufacturer are used.
