In manual mode, the unit can also be used for synchronized cardioversion of certain atrial or
ventricular arrhythmias. A qualified physician must decide when synchronized cardioversion is
appropriate.
The advisory function should be used to confirm ventricular fibrillation or wide complex
ventricular tachycardia (greater than 150 beats per minute) in patients meeting the three
conditions indicating lack of circulation (listed above).
Intended Use — ECG Monitoring
The unit is intended for use when ECG monitoring is indicated to evaluate the patient’s heart
rate or ECG morphology. In ECG monitoring mode, the unit is intended to be used by
personnel who are qualified by training in the use of the R Series defibrillator, basic life and/or
advanced life support, or other physician-authorized emergency medical training.
Intended Use — Real CPR Help
The Real CPR Help function provides visual and audio feedback designed to encourage
rescuers to perform chest compressions at the AHA/ERC recommended rate of 100
compressions per minute. Voice and visual prompts encourage a compression depth in
accordance with AHA and/or ERC recommendations of 2 inches (5 cm) minimum for adult
patients.
Defibrillator Complications
Inappropriate defibrillation or cardioversion of a patient (for example, with no malignant
arrhythmia) may precipitate ventricular fibrillation, asystole, or other dangerous arrhythmias.
Defibrillation without proper application of electrodes or paddle electrolyte gel might be
ineffective and cause burns, particularly when repeated shocks are necessary. Erythema or
hyperemia of the skin under the paddles, or electrodes often occurs; this effect is usually
enhanced along the perimeter of the paddles or electrodes. This reddening should diminish
substantially within 72 hours.
Defibrillator Output Energy
R Series defibrillators can deliver as much as 200 joules into a 50 ohm impedance. The energy
delivered through the chest wall, however, is determined by the patient’s transthoracic
impedance. An adequate amount of electrolyte gel must be applied to the paddles and a force of
10 to 12 kilograms (22 to 26.4 pounds) must be applied to each paddle in order to minimize this
impedance. If hands-free therapy electrodes are used, make sure that they are properly applied.
(Refer to the instructions on the electrode package).
