When do you use a double lumen tube?
Double lumen tubes play a crucial role in:
- Airway management during thoracic surgery.
- Anatomical lung separation or isolating normal from the diseased lung in situations such as: Massive hemorrhage from one lung.
- Differential lung protective ventilation in case of lung transplantation patients.
