What is the recommended ratio of chest compressions to rescue breaths in adult CPR according to American heart association (AHA)

Appeared in: RUHS, Jaipur, M.Sc Nursing Entrance Exam-2024

Explanation

  • The American Heart Association (AHA) recommends a universal compression-to-ventilation ratio of 30:2 for single rescuers treating victims of all ages.
  • For adult CPR, this ratio of 30 chest compressions followed by 2 rescue breaths is the standard for both single and two-rescuer scenarios.
  • This ratio provides a crucial balance between maintaining blood circulation through compressions and providing oxygen through rescue breaths.

Why Other Options Were Wrong

  • Option A: This ratio is not for adults. It is specifically for two-rescuer CPR on infants and children.
  • Option C: This is not a standard compression-to-ventilation ratio recommended by the AHA for any age group.
  • Option D: This is not a standard compression-to-ventilation ratio recommended by the AHA. It may be confused with outdated protocols or other non-CPR procedures.

Clinical Relevance
  • Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain CPR compression-to-ventilation ratio for adults (AHA guidelines) as background academic context rather than a clinical decision trigger.
  • Performing high-quality CPR with the correct compression-to-breath ratio is a fundamental, life-saving skill for nurses that directly impacts patient survival after cardiac arrest.
  • Minimizing interruptions in chest compressions to less than 10 seconds is paramount, as any pause significantly decreases coronary and cerebral perfusion pressure, worsening outcomes.
  • What if? If the victim was a 5-year-old child and two nurses were present, the correct ratio would change to 15:2 to provide more frequent ventilations, reflecting the higher likelihood of a respiratory cause for the arrest in pediatric patients.
How to Approach the Question
  • First, identify the key components of the question: the procedure (CPR), the patient population (adult), and the governing body (American Heart Association).
  • Recognize this as a factual recall question based on established clinical guidelines.
  • Recall the standard AHA ratio for adult CPR, which is a foundational piece of knowledge in basic life support.
  • Evaluate the options. Eliminate ratios used for other age groups (like 15:2 for two-rescuer child CPR) or those that are not standard (15:1, 5:1).
  • Select the option that matches the current, universally applied AHA guideline for adult CPR.
