Obstructed ETT or Circuit

🔑 Key Priorities

• Diagnose obstruction rapidly (↑PIP, ↓TV, silent chest)

• Rule out kinking, secretions, biting, circuit failure

🧠 Team Actions

Role	Task
Team Leader	Declare airway emergency, lead swap-out plan
Airway Manager	Disconnect circuit, bag manually
Assistant	Suction ETT, prepare replacement tube

🧭 Management Algorithm

1. Sudden ↑ airway pressure or ↓ tidal volume

2. Disconnect circuit, bag manually

3. Pass suction catheter → clear or resistance?

4. Consider biting, mucus plug, kinking, blood clot

5. Replace ETT if unresolved

6. Inspect circuit for obstruction

🔄 Ideal Crisis Flow

     Sudden ↑PIP or ↓TV on Ventilation
                  ↓
    Disconnect + Manual Bag Ventilation
                  ↓
    Suction / Check for Obstruction / Bite
                  ↓
     Replace ETT or Circuit if Unresolved
