The primary goal of cardiopulmonary resuscitation (CPR) is adequate perfusion to the brain and vital organs. High-quality chest compressions for adults are at least 2 in (5 cm) deep to adequately pump blood but no more than 2.4 in (6 cm) deep to prevent unnecessary client injury (Option 1). The chest should recoil completely after each compression to allow complete refilling of the heart chambers, which promotes effective perfusion.
(Option 2) Interruption of compressions should be minimized; at least 60% (preferably more) of the total resuscitation time should be made up of compressions. For adults (and in single-rescuer CPR for any age), a cycle of 30 compressions followed by 2 rescue breaths provides the best outcome. If the client has an advanced airway, continuous compressions and 10 breaths/min should be provided.
(Option 3) Correct hand placement is in the center of the chest, on the lower half of the sternum (breastbone). Hand placement on the upper half of the sternum does not provide adequate perfusion.
(Option 4) Studies have shown better client outcomes due to improved perfusion with a compression rate of 100-120/min.
Educational objective: For high-quality adult cardiopulmonary resuscitation, compressions should be in the center of the chest; at a rate of 100-120/min; and at least 2 in (5 cm) but no more than 2.4 in (6 cm) deep for adequate perfusion without unnecessary client injury. Compression interruption should be minimized (eg, 30 compressions to 2 rescue breaths).
