Chest compressions are the rhythmic, forceful presses on the lower half of the breastbone performed during CPR to manually pump blood from the heart to the brain and other vital organs when the heart can no longer do so on its own. They are the foundation of resuscitation and the highest-priority action in cardiac arrest.
Effective compressions follow specific targets: a depth of at least 2 inches (5 cm) in adults, a rate of 100–120 per minute, full chest recoil after each press, and minimal interruptions. Poor technique — shallow depth, leaning on the chest, or frequent pauses — sharply reduces blood flow and survival. Compressions are combined with rescue breaths and, when available, an AED.
Because compression quality directly determines outcomes, CPR Certification Labs uses real-time feedback technology in its hands-on, AHA-aligned CPR and BLS training so students can measure and perfect depth, rate, and recoil. See also Quality of Chest Compressions and the CPR Cycle.
