Using the DigiTrak XT Recorder
1-12 DigiTrak XT Recorder Instructions for Use
Step Three — Preparing the Patient
Before You Begin
„
Insert a fresh AAA battery with each patient. Be sure to observe the correct battery
polarity.
„
Instruct the patient not to tamper with the recorder, remove the battery, or disconnect the
patient cable.
To prepare the patient
1
Prepare the patient’s skin prior to applying the electrodes. Skin is a poor conductor of
electricity, so skin preparation is important in achieving good electrode-to-skin contact.
–
If necessary, clip hair at the electrode sites (or shave sites, if needed).
– Clean and abrade the skin at the electrode site. Wash skin thoroughly with soap and
water.
– Dry the electrode sites briskly to increase capillary blood flow in the tissues and to
remove oil and skin cells.
2
Attach the leads to the electrodes before placing them on the patient.
3
Apply the electrodes by peeling them, one at a time, from the protective backing and
sticking them firmly to the patient’s skin. (Refer to Figure 1-1 for proper electrode
placement.) Press around the entire edge of each electrode to ensure they are secure. Make
sure the lead wires do not pull on the electrodes.
