PEDIATRICS 26
-The infant's trachea is approx. 4 mm wide compared
with the adult's width of 20 mm.
pediatric anatomy - CORRECT ANSWER -smaller
shorter airways
-underdeveloped cartilage
-lung size in proportion to body weight
-nose breathers
-poor intercostal muscles
-irregular respiratory pattern
-increased oxygen metabolic needs
-fewer alveoli and bronchioles
-enlarged tonsils
-horizontal eustachian tubes
-flexible larynx
-resistance
-seasonal variations
-underdeveloped cricoid cartilage (leads to laryngeal
narrowing)
-susceptible to dynamic collapse
-airways muscles less functional
horizontal - CORRECT ANSWER _____ eustachian
tubes don't allow for easy drainage of fluid from the
tympanic membranes, resulting in fluid accumulation.
cricoid cartilage - CORRECT ANSWER children
younger than 10 years old have underdeveloped ____
____. This results in laryngeal narrowing which
increases the risk of aspiration into the lower airway.
