Final answer:
Manual defibrillation is recommended for individuals aged 1 to 12 years during a cardiac arrest. AEDs are designed for public use, whilst defibrillator paddles are used professionally in hospitals.
Step-by-step explanation:
In the treatment of cardiac arrest, manual defibrillation is generally recommended for individuals aged 1 to 12 years. Defibrillation is a crucial life-saving procedure that involves the delivery of a controlled electrical shock to the heart in order to restore a normal heartbeat. In emergency situations outside of a hospital setting, automated external defibrillators (AEDs) are commonly used by the public, and these devices are increasingly available in public spaces. They are designed to be user-friendly and provide verbal instructions to aid nonmedical personnel in their use. AEDs automatically diagnose the heart's condition and deliver the shock with appropriate energy and waveform. In a hospital setting, manual defibrillation using defibrillator paddles is more common, especially in cases that require a healthcare professional's expertise. CPR is often administered before the use of an AED, as recommended by health guidelines.
