For adults, how deep should chest compressions be delivered?

At least 1 inch
At least 2 inches
At least 3 inches
At least 4 inches

The correct answer is: At least 2 inches

Delivering chest compressions to adults requires a depth of at least 2 inches. This depth is essential to ensure that adequate blood flow is generated during cardiopulmonary resuscitation (CPR). Compressions that are too shallow may not effectively circulate blood, especially in an adult whose torso is significantly larger and requires sufficient force to reach the heart and major arteries. The recommendation to compress at least 2 inches aligns with guidelines to promote effective resuscitation techniques, improving the chances of restoring circulation and aiding in a successful outcome. Compressions should also be delivered at a rate of 100 to 120 per minute, and ensuring the correct depth helps maintain the effectiveness of each compression.
