According to the Coyne First Aid booklet, what should you do during chest compressions?

During chest compressions, the objective is to effectively circulate blood to vital organs, particularly during a cardiac emergency. Pressing hard and fast ensures that compressions are forceful enough to create adequate blood flow. The recommended depth for chest compressions in adults is about 2 to 2.4 inches, and the rate should be around 100 to 120 compressions per minute. This combination of speed and force is critical for maintaining blood circulation until professional medical help arrives.

The focus on substantial and rapid compressions helps to optimize the chances of survival and brain function in an individual experiencing a cardiac arrest.

In contrast, pressing softly and slowly would not provide sufficient blood flow and could significantly hamper the effectiveness of resuscitation efforts. Taking breaks every 10 seconds can disrupt the continuity needed for effective compressions, while pressing for only 5 seconds and then releasing would not maintain the necessary perfusion to the heart and brain.
