== <u>Pediatric Airway Diameters</u> == | == <u>Pediatric Airway Diameters</u> == | ||
===== Average neonatal trachea has an AP diameter of about 4.3 mm for both males & females ===== | |||
Trachea grows uniformly in males and females to about 14 mm at the age of 15 yrs old | |||
At this time, female trachea stops growing, but male trachea continues to grow to 16–18 mm by age of 19 | |||
trachea is elliptical in shape, with the transverse diameter being larger than AP diameter Sizing of airway devices should be based on the smaller (anteroposterior) diameter. | |||
