What is the recommended time for the entire defibrillation sequence to be completed?

• A. Less than two seconds
• B. Less than three seconds
• C. Less than four seconds
• D. Less than five seconds

Answer: (D)

The recommended time for the entire defibrillation sequence to be completed is less than five seconds because prompt and efficient defibrillation is crucial for the successful restoration of a normal heart rhythm in a patient experiencing cardiac arrest. The American Heart Association emphasizes that minimizing the time between rhythm analysis and shock delivery enhances the chances of survival and the likelihood of a favorable neurological outcome. Achieving this within a five-second window allows for swift action while ensuring that the patient is not exposed to unnecessary delays, which could negatively impact the effectiveness of the treatment. The focus on rapid defibrillation reflects a key aspect of advanced cardiac life support protocols, which aim to provide immediate and effective care for patients in critical situations.
