أثناء إنعاش بالغ مع وجود أنبوب رغامي، ما الإجراء الصحيح للضغطات والتنفس؟

During adult CPR with an endotracheal tube in place, what is the correct approach to compressions and ventilation?

1. Compressions at 80/min with a breath every 2 seconds
2. 30 compressions then 2 breaths, pausing compressions for breaths
3. 15 compressions then 2 breaths as in paediatric CPR
4. Continuous compressions at 100–120/min with one breath every 6 seconds

Answer: D) Continuous compressions at 100–120/min with one breath every 6 seconds. With an advanced airway, compressions continue without pauses at 100–120/min and a breath is given about every 6 seconds (10/min). Overventilation raises intrathoracic pressure and cuts venous return.
