What is the key to effective chest compressions?

The key to effective chest compressions is to push hard and push fast. When performing chest compressions, the goal is to ensure adequate blood circulation to vital organs during cardiac arrest. Compressions should be delivered at a rate of 100 to 120 compressions per minute and should depress the chest to a depth of at least 2 inches in adults. This technique helps create enough blood flow to sustain life until professional medical help can arrive.

Performing compressions with force ensures that the heart is adequately compressed and can pump blood effectively. Additionally, speed is crucial, as a faster rate keeps the rhythm necessary to maintain blood circulation. Therefore, the correct approach encapsulates both intensity and speed to maximize the chances of survival in a critical situation.
