During adult cardiopulmonary resuscitation, the recommended depth and rate of chest compressions are:

• A At least 5 cm, rate 100 to 120 per minute ✓
• B At least 3 cm, rate 80 to 100 per minute
• C At least 6 cm, rate 120 to 140 per minute
• D At least 4 cm, rate 60 to 80 per minute

Explanation

Current guidelines specify compressing the lower half of the sternum by at least 5 cm (2 inches) but not more than 6 cm, at a rate of 100 to 120 per minute. Rates above 120 reduce compression depth because of inadequate filling time, which is the fact that eliminates option C. Depths under 5 cm fail to generate adequate coronary and cerebral perfusion pressure.
