Final answer:
The focus on CPR has shifted to emphasize 'Chest Compressions' over the previous 'A-B-C' sequence, which involved Airway and Breathing before Compressions. 'Mouth-to-mouth' ventilation has been de-emphasized for untrained bystanders, promoting 'Hands-Only' CPR to encourage prompt action in cardiac arrest cases.
Step-by-step explanation:
The increased focus on CPR (Cardiopulmonary Resuscitation) in recent updates is on 'Chest Compressions'. Previously, the sequence recommended by the American Heart Association for CPR was 'A-B-C', which stands for Airway, Breathing, and Compressions. However, the order was changed to emphasize 'C-A-B', which stands for Compressions, Airway, and Breathing. This change highlights the importance of starting chest compressions as quickly as possible.
What was REMOVED is the routine use of mouth-to-mouth ventilation for untrained bystanders. The updated guidelines focus on 'Hands-Only' CPR, which is just chest compressions, for untrained rescuers or those uncomfortable with the mouth-to-mouth ventilation. This is to simplify the process for lay rescuers and to increase the likelihood of bystanders taking action in an emergency cardiac arrest situation.
