What causes stridor?
Stridor is a noisy or high-pitched sound with breathing. It is usually caused by a blockage or narrowing in your child’s upper airway. Some common causes of stridor in children are infections and defects in the child’s nose, throat, larynx, or trachea that the child was born with.
What does stridor mean in breathing?
Less musical sounding than a wheeze, stridor is a high-pitched, turbulent sound that can happen when a child inhales or exhales. Stridor usually indicates an obstruction or narrowing in the upper airway, outside of the chest cavity.

What is a stridor in voice?
Stridor is a high-pitched sound you make when you breathe through a narrow or partly blocked airway. Air can’t flow through your lungs smoothly, so it’s harder to breathe.
Is stridor serious in adults?
In children, acute stridor often accompanies upper respiratory tract infection. In children, chronic stridor usually occurs with congenital conditions. Stridor in adults is much less common. Chronic stridor in adults often indicates serious underlying pathology.
Is stridor on inhale or exhale?
Stridor is a high-pitched sound heard best when your child is breathing in (inhaling). It can also be heard when your child is breathing out (exhaling). Noisy breathing, or stridor, is most often a symptom of a throat or airway problem.

Is stridor a symptom of asthma?
Stridor: Causes and possible diseases in adults In adults, expiratory stridor is more common. The causes of stridor often are associated with the bronchi and the lungs. The causes of expiratory stridor in adults often include diseases of the respiratory tracts, which make exhalation difficult: Bronchial asthma.
What medication is used for stridor?
Treatment of Stridor Nebulized racemic epinephrine (0.5 to 0.75 mL of 2.25% racemic epinephrine added to 2.5 to 3 mL of normal saline) and dexamethasone (10 mg IV, then 4 mg IV every 6 hours) may be helpful in patients in whom airway edema is the cause.
What is the difference between wheezing and stridor?
Wheezing is a musical sound produced primarily during expiration by airways of any size. Stridor is a single pitch, inspiratory sound that is produced by large airways with severe narrowing; it may be caused by severe obstruction of any proximal airway (see A through D in the differential diagnosis outline below).
