(strī′dŏr)

(strī′dor″)
[L., stridor, rattling, buzzing]
A high-pitched, harsh sound occurring during inspiration, often heard without the use of a stethoscope. It is a sign of upper airway obstruction, which may indicate the presence of a life-threatening condition, e.g., epiglottitis. The lack of stridor should never be interpreted as a sign that the upper airway is patent in the patient with signs of having difficulty breathing.
