Preparations Before Operation
Chapter 3 Preparations Before Operation
3.1 Preparing the Patient
3.1.1 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.
3.1.2 Cleaning the Skin
Thorough skin preparation is very important. The skin is a poor conductor of electricity and
frequently creates artifacts that distort the ECG signals. By performing methodical skin
preparation, you can greatly 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 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 to increase capillary blood flow and to remove the dead, dry skin cells and oils.
4.
Use the disposable frosting film in the standard accessory list to get good ECG waveform.
NOTE: Rub the skin with a gauze pad to increase capillary blood flow if you don’t operate
the steps above.
3.2 Connecting the Patient Cable
WARNING
The performance and electric shock protection can be guaranteed only if the original
patient cable and electrodes of the manufacturer are used.

following symbol:
NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects and people.
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless)
telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV
broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic
environment due to fixed RF transmitters, an electromagnetic site survey should be
considered. If the measured field strength in the location in which the PADECG is used
exceeds the applicable RF compliance level above, the PADECG should be observed to
verify normal operation. If abnormal performance is observed, additional measures may
be necessary, such as reorienting or relocating the PADECG.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
The ISM (industrial, scientific and medical) bands between 0,15 MHz and 80 MHz are
