CPR Steps: The Change From A-B-C to C-A-B

The old AHA CPR guidelines, as per medical reviewers, stated the ABC of the CPR method, which meant rescue breaths should be given before chest compressions. However, studies showed that rescuers hesitated to perform rescue breaths to open the airway on time. Thus, lessening the percentage of people actually performing the full cycle of cardiopulmonary resuscitation. Giving chest compressions to the patient is what’s truly essential to get the blood flowing again for patients suffering from cardiac arrest.

To avoid hesitation and provide the best CPR procedure for patients in a usual emergency situation of a heart attack or sudden cardiac arrest, the American Heart Association updated the CPR steps from A-B-C to C-A-B, where chest compressions come first, followed by airway and breathing.

Here, the chest compressions must be 2 inches deep for adults and 1.5 inches in depth for children. The compression-first techniques reduce the time, originally wasted on the opening of the airway for performing rescue breaths first. The emergency situation is now more manageable for lay responders, even with limited knowledge or training.

This builds for a higher success rate than the previous guidelines. Also, the ventilation gets to the patient on time after faster initiation.

Rescue Steps In C-A-B Method of CPR

When giving mouth-to-mouth rescue breaths to patients in a life-threatening situation with higher chances of permanent brain damage, the following steps must be considered:

  • The first step is to pinch their nose and keep the airway open. Use the tilt head/lift chin method.
  • Inhale deeply and seal the patient’s mouth with yours as the first responder after proceeding to perform rescue breaths. In this case, CPR barrier masks are highly recommended as per the usual medical advice listed in our nationally accredited CPR courses.
  • The execution of rescue breaths would be effective if the chest is rising and falling with every breath that the patient receives because the purpose of performing this is to manually add air to the patient’s body.

Conclusion:

With this change in the CPR method to tackle a sudden cardiac arrest medical emergency situation, hands-only CPR has become a common and most reliable technique without heavily depending on mouth-to-mouth rescue breaths first. The first rescuer can easily use their heel of hand when to give the chest compression. And if the second responder or rescuer is available, only then can the second person focus on giving two rescue breaths. Otherwise, hands-only CPR is enough to put the patient in the recovery position and help them recuperate fast.
