You are still performing CPR as a single rescuer. The AED detects a shockable rhythm and advises a shock. After delivering 1 shock you immediately resume CPR with what ratio of compressions to breaths?
The Correct Answer and Explanation is :
After delivering a shock with an Automated External Defibrillator (AED), the recommended ratio of compressions to breaths for CPR performed by a single rescuer is 30:2. This means that for every 30 chest compressions, you should give 2 rescue breaths.
Explanation:
The 30:2 compression-to-breath ratio is part of the CPR guidelines set forth by organizations like the American Heart Association (AHA). This ratio applies to adult victims of cardiac arrest and is designed to optimize blood flow to vital organs, especially the brain and heart, during the critical moments of resuscitation.
- Chest Compressions: The primary goal of CPR is to maintain blood circulation until advanced medical help arrives. Chest compressions create artificial circulation by manually pumping blood to vital organs. Compressions should be delivered at a rate of 100 to 120 per minute and should be at least 2 inches deep. Proper technique, including allowing full chest recoil between compressions, is essential to maximize blood flow.
- Rescue Breaths: While chest compressions are the most crucial component of CPR, rescue breaths provide oxygen to the lungs. After delivering 30 compressions, taking a moment to give 2 breaths helps ensure that the victim’s blood is adequately oxygenated. Each breath should be given over 1 second and should cause the chest to rise visibly.
- Importance of the Ratio: The 30:2 ratio balances the need for compressions and breaths. Too few breaths may lead to inadequate oxygenation, while too many breaths can interrupt compressions and reduce blood flow. This systematic approach allows for continuous circulation and oxygenation, maximizing the chances of a successful resuscitation.
In summary, after delivering a shock with an AED, resume CPR with a 30:2 ratio of compressions to breaths, maintaining focus on effective chest compressions while ensuring the victim receives necessary oxygen.
