In adult CPR, how should compressions be performed?

In adult CPR, the compressions should be performed using both hands at a steady pace and with sufficient depth to effectively circulate blood. The ideal depth for adult chest compressions is generally about 2 to 2.4 inches (5 to 6 cm) and should be delivered at a rate of 100 to 120 compressions per minute. This depth and rate are crucial because they ensure that enough blood is pumped to vital organs, which can significantly increase the chances of survival.

The emphasis on both hands allows for greater force to be applied during compressions, which is necessary to compress the chest adequately. Steady pacing is important to maintain an effective rhythm, making it easier to perform the compressions correctly over a prolonged period. Using adequate depth rather than a light touch maximizes blood flow to the heart and brain, which is essential during cardiac arrest.

While any approach that deviates from this method may not generate sufficient blood flow, using one hand or compressing lightly could compromise the effectiveness of CPR and diminish the likelihood of a positive outcome.
