Children are more susceptible to airway obstruction than adults. One millimeter of edema in a small caliber pediatric airway (4mm diameter in a neonate) leads to dramatically increased airway resistance compared to the same amount of swelling in an adult (d=8mm) due to the effect of radius to the 4th power on rate of flow. The relatively large tongue of children can also collapse against the posterior pharynx, resulting in airway obstruction. Maneuvers such as the chin-lift or
