Final answer:
Manual defibrillation is a lifesaving technique recommended for treating cardiac arrest, particularly for ventricular fibrillation.
Step-by-step explanation:
Manual defibrillation is indeed a recommended technique for treating cardiac arrest when performed by trained medical personnel.
A defibrillator delivers a large electrical charge in a short burst to the heart through a set of paddles or pads, which can be a lifesaver during a cardiac emergency. This treatment is known as defibrillation and is particularly effective for conditions such as ventricular fibrillation, a severe form of arrhythmia where the heart beats in a rapid, irregular manner, preventing effective blood pump.
For public use, automated external defibrillators (AED) are available and are designed to be used by nonmedical personnel to reestablish a normal sinus rhythm in a person with fibrillation. These devices automatically diagnose the patient's heart rhythm and apply the correct level of shock. It's commonly advised to perform CPR prior to using an AED.
