Which of the following statements best describes the airway of an infant or small child compared to that of an adult?
A
The airway has a larger diameter relative to body size.
B
The airway is longer and less flexible.
C
The airway contains more cartilage and is less prone to collapse.
D
The airway is proportionally narrower and more easily obstructed.
Verified step by step guidance1
Understand the anatomical differences between the airway of an infant or small child and that of an adult. The airway of an infant is proportionally narrower compared to their body size, making it more susceptible to obstruction.
Recognize that infants and small children have smaller airways with less rigid cartilage, which can make their airways more prone to collapse under certain conditions.
Consider the physiological implications of a narrower airway. For example, even minor swelling or mucus accumulation can significantly reduce airflow due to the smaller diameter.
Compare the flexibility and length of the airway. In infants, the airway is shorter and less developed, which can contribute to increased vulnerability to obstruction.
Review the correct answer: 'The airway is proportionally narrower and more easily obstructed,' and understand why this is the best description based on the anatomical and physiological characteristics of an infant's airway.
