When performing CPR, how can rescuers ensure optimal effectiveness?

Minimizing interruptions to chest compressions is crucial for optimal effectiveness during CPR. Continuous chest compressions help maintain blood flow to vital organs, particularly the brain and heart. Interruptions can lead to a decrease in coronary and cerebral perfusion pressure, reducing the likelihood of a successful resuscitation. The AHA (American Heart Association) emphasizes that high-quality CPR focuses on minimizing any breaks in compressions, ensuring that they are delivered at the correct depth (about 2-2.4 inches) and at a recommended rate (100-120 compressions per minute).

While a higher compression rate or increased force may seem beneficial, they do not necessarily enhance the effectiveness of CPR if it results in interruptions or poor technique. Similarly, while airway interventions are important, excessive focus on them at the expense of continuous compressions can be detrimental to the patient’s outcome. Thus, maintaining uninterrupted chest compressions is the foundation of effective CPR practice.
