Adv: Best for ventilation/control of each side.
Dis: bulky therefore not in difficult intubation, tracheostomy
2. Single lumen ETT with bronchial blocker
Adv: Use in (pot.) difficult airway, tracheostomy, if ETT already in situ e.g. ICU.
Dis: More specialised kit and technique. Needs fibreoptic scope.
3. Single lumen ETT advanced into main bronchus ( + fibreoptic if left sided)
Adv: Useful in emergency with most simple/available kit.
Dis: no control over non-intubated lung.
