Chest Compression Techniques for Adult CPR

During adult cardiopulmonary resuscitation (CPR), the correct compression site is critical for effectiveness. The recommended area is the lower half of the sternum, specifically at the junction of the middle and lower one-third of the breastbone. A simple way to locate this area is to find the point directly in the center of a line drawn between the two nipples. When performing compressions, place the heel of one hand on the sternum and the other hand on top for added pressure, keeping the arms straight and shoulders directly above the hands.

Proper Compression Technique

It's essential to maintain consistent, uninterrupted pressure during CPR. The compressions should be firm and deep enough to stimulate blood circulation, ideally between 5 to 6 centimeters in depth. The recommended rate is 100 to 120 compressions per minute, ensuring a steady rhythm without pauses. Maintaining this pace helps simulate the natural heartbeat and improves the chances of survival.

Single Rescuer CPR Guidelines

When performing CPR alone, follow a ratio of 30 compressions to 2 rescue breaths. This sequence should be repeated continuously until emergency medical help arrives or the patient shows signs of recovery. The key is to avoid interruptions and keep the blood flowing as efficiently as possible.

Two-Person CPR Coordination

In a two-rescuer scenario, rescuers should switch roles every 5 minutes to prevent fatigue and maintain the quality of compressions. It's crucial to coordinate the switch without interrupting the rhythm of compressions. During this process, defibrillation can be administered if an AED (Automated External Defibrillator) is available. Immediately after a shock, continue with chest compressions without waiting to check for a pulse, as this helps maintain circulation and increases the likelihood of a successful outcome.

Key Considerations for Effective CPR

Continuous chest compressions are vital for maximizing the success of CPR. Even when using advanced equipment like a defibrillator, it's important not to delay or stop compressions unless absolutely necessary. Every second counts in these critical moments, and maintaining pressure can significantly improve the patient's chances of survival.
