How deep should compressions be when performing adult CPR?

• A. 1 inch
• B. 2 inches
• C. 3 inches
• D. 1.5 inches

Answer: (B)

When performing adult CPR, the recommended depth for chest compressions is approximately 2 inches (or 5 centimeters). This depth is crucial for effectively compressing the heart and creating adequate blood flow to vital organs during cardiac arrest. Compressions should be firm and deliberate, allowing for full recoil between compressions to ensure the heart can refill with blood. The reason this depth is emphasized is that it helps generate enough pressure to circulate blood effectively; too shallow compressions may not optimize blood flow, whereas compressions that are too deep could potentially cause injury to the torso. Following these guidelines maximizes the chances of survival until emergency medical assistance arrives.
