What is the recommended chest compression depth for adults (8 years and older) during CPR?

• A. 1 1/2 - 2 Inches
• B. 1 - 1 1/2 Inches
• C. 1/2 - 1 Inch
• D. 2 - 3 Inches

Answer: (A)

Generating adequate blood flow during CPR depends on chest compressions that are deep enough to pump blood but not so deep as to cause injury. For adults aged 8 and older, aim for roughly 1.5 to 2 inches (about 4 to 5 cm) of depth with each compression. This depth helps create enough intrathoracic pressure to perfuse the heart and brain, while staying within a safer range to minimize injury. Compressions that are too shallow reduce blood flow, while overly deep compressions increase the risk of injury and are not routinely recommended.
