What is the minimum depth of chest compressions for an adult in cardiac arrest?

1 inch
1.5 inches
2 inches
2.5 inches

The correct answer is: 2 inches

The minimum depth of chest compressions for an adult in cardiac arrest is established at 2 inches. This guideline is based on the recommendations from resuscitation organizations, which emphasize the importance of delivering effective compressions that are deep enough to create adequate blood flow during cardiac arrest. Compressions that are too shallow do not provide enough pressure on the heart to maintain circulation, thus failing to support oxygen delivery to vital organs. In addition to the depth, it's crucial that the compressions are delivered at a rate of 100 to 120 compressions per minute and are allowed to fully recoil between compressions to maximize venous return. The focus on a depth of at least 2 inches is aimed at ensuring sufficient pressure is applied to help achieve perfusion during the critical moments of cardiac emergency.
