Question 1622 Deck Safety
70% to passHow deeply should the sternum be depressed when applying chest compressions on an adult victim during CPR?
A
1-1/2 to 2 inches
B
1/2 inch or less
C
1 to 1-1/2 inches
D
1/2 to 1 inch
AI Explanation
The correct answer is A) 1-1/2 to 2 inches. This depth of chest compression is the current recommendation from the American Heart Association for adult CPR. Compressing the sternum 1-1/2 to 2 inches allows for adequate circulation and blood flow during CPR. Anything less than 1-1/2 inches (options B and C) would not provide sufficient force to effectively pump the heart and circulate blood. Compressing more than 2 inches (not an option provided) could risk injury to the victim.
