Question

Research has shown that for every minute defibrillation is delayed, survival decreases by

A) 1%
B) 2%-3%
C) 4%-6%
D) 7%-10%

Answer 1

For every minute defibrillation is delayed, survival decreases by 2%-3%; timely defibrillation is critical for survival.

Step-by-step explanation:

Research has indicated that for every minute defibrillation is delayed, the chance of survival decreases significantly. The correct answer to the question of how much survival decreases for every minute that defibrillation is delayed is B) 2%-3%. This is based on the fact that a timely defibrillation, particularly within the first few minutes following a cardiac arrest, is critical for increasing the chances of survival. Defibrillators work by delivering a brief electric current through the heart, causing a short but strong contraction which can reset the heart's rhythm back to normal.
