El-Ganzouri 1996 simplified airway risk index (0/1/2)

El-Ganzouri 1996 simplified airway risk index (0/1/2): mouth opening >4 cm=0, <=4=1; thyromental >6.5 cm=0, 6.0-6.5=1, <6.0=2; original Mallampati 1/2/3 = 0/1/2 (class 4 not used); neck >90 deg=0, 80-90=1, <80=2; can prognath true=0, false=1; weight <90 kg=0, 90-110=1, >110=2; intubation history none/questionable/definite = 0/1/2. Max 12. High risk if score >=4. Not an intubation order; magent does not examine the airway.
