Cardiac arrest in infants and children should initially be considered to be secondary to respiratory arrest. Sudden cardiac death, ventricular fibrillation, and pulseless ventricular tachycardia are much less likely to occur in children than in adults.

Complications of defibrillation include soft tissue injury, myocardial injury and cardiac dysrhythmias. The availability of multifunctional electrode pads has decreased the potential for soft tissue injuries such as chest burns.

When encountering a patient who is unresponsive and has been down for an unknown time, assess the patient, summon help and initiate CPR immediately if indicated. Perform CPR until the defibrillator or AED is brought to the patient's side.

Once an advanced airway is in, the compression and ventilation cycles are no longer delivered 30:2. Now, the compressor will continue to deliver compressions continuously at a rate higher than 100 compressions/min, without pausing.

Two major types of defibrillators are available: biphasic and monophasic. The biphasic defibrillator, which is more likely to be found in the clinical setting, produces either a biphasic rectilinear waveform or truncated exponential waveform.

If no pulse is present, begin a sequence of 30 chest compressions followed by 2 ventilations/breaths. Keep your hands on the lower half of the sternum and compress it at least 2 inches (5 cm) at a rate of at least 100 compressions/min.

When confronted with a patient who has just become unresponsive, prepare for immediate defibrillation. As soon as the defibrillator is available and the patient is connected to the monitor, assess the rhythm.

When performing defibrillation, take care to avoid excessive moisture on the chest or around the patient. Although it is unlikely that there will be current leaks from the patient onto a wet floor, take care to avoid creating an electrical hazard.

Patients “found down” or who have just become unresponsive can have other rhythms present besides VF or pulseless VT (e.g., pulseless electrical activity or asystole). Defibrillation is contraindicated in people with pulseless electrical activity.

Victims of sudden cardiac arrest as a result of traumatic injuries do not usually survive. The heart, aorta and pulmonary arteries may have sustained injury that will prevent the resumption of normal cardiovascular function.

When sudden cardiac arrest occurs and the heart is in VF or pulseless VT, ventricular contraction is absent and circulation of blood comes to a standstill. To initiate CPR, compress the heart between the sternum and vertebral column.

When the heart is in VF or pulseless VT, applying a “burst” of current across the myocardium will cause all the membrane channels involved in excitation-contraction coupling to be activated into the absolute refractory period.

Cardioversion is performed to suppress dysrhythmias that produce a rapid pulse and cause the patient to become unstable. Such dysrhythmias include supraventricular tachycardia, atrial fibrillation/flutter and unstable monomorphic VT.

For every minute that the heart is in ventricular fibrillation without treatment, the potential for the initial defibrillation to be successful and for the victim of sudden cardiac arrest to survive decreases by 7% to 10%.

Defibrillation entails passing a burst of electrical current across the chest wall through the myocardium to terminate the chaotic electromechanical activity impeding the ventricles from ejecting blood into the circulation.
