Laryngeal obstruction
Stiff lungs
Stiff neck
What are the predictors of difficult ETT placement?
The strongest independent predictors of difficult intubation
Mallampati

Describe an Aintree catheter
56 cm long
19Fr
6.5mm external diameter
hollow and stiff enough to facilitate railroading of ETT
>= 7
4.7 inner diameter
Easily preloaded over ≤ 4.2 mm diameter fibrescope
Comes with 2 rapifit adaptors - allows oxygen administration but be cautious of
barotrauma/perforation
Max. depth 26cm
Max O2 flow rate = 2L/min
