POSITIONING AND POLARITY
The international guidelines indicate various placements as equally effective for the treatment of atrial or
ventricular arrhythmias.
The following figures show the application sites commonly used and recommended by most manufacturers
of defibrillators. Choose the most appropriate points of application of the therapy according to
manufacturer's instructions for use of the defibrillator to be used.
For ease of placement and for training purposes, the anterior-lateral side (Fig.1) is preferred for
arrhythmias defibrillation and cardioversion; the anterior-posterior side (Fig.2) is more common in
hemodynamics and in transthoracic pacing and recommended in case of use of electrodes for adults on
pediatric patients.

which electrode pad (apex / sternum) is placed in one of the two positions.
Regarding the polarity of the electrodes in unique version adult/pediatric, follow the directions on the
labels of the electrode pad (according to the instructions of the manufacturer of the defibrillator to be
used).
SIDE EFFECTS
• Plate adhesive may cause light cutaneous irritation.
• The prolonged transthoracic stimulation or the repeated administration of defibrillation shock may cause
more or less noticeable skin reddenings according to the supplied energy.
• A lack in adhesion and/or air presence under the electrode may cause burnings.
PRECAUTIONS AND WARNINGS
• Use the product only on defibrillators brands indicated on the labels.
• Check that the product is compatible with the specific model of defibrillator intended to be used.
• Read the instructions for use of the defibrillator, with particular attention on the placement of
multifunction electrodes, their polarity and the power to be supplied.
• In paediatrics and for some models of automatic defibrillators the use of specific reducing power devices
or the adoption of special precautions may be required. Always pay a special attention to energy levels
set on the defibrillator and that can be delivered to the paediatric patient (see section "MODE OF USE").
