Stridor is a high-pitched squeaking or whistling sound, usually due to an obstruction in an airway. Stridor is a sign of an underlying health issue rather than a diagnosis or disease in itself.
What is a common example of stridor?

What is expiratory stridor?
Expiratory stridor occurs when your child breathes out and it indicates a problem further down the windpipe. Biphasic stridor occurs when your child breathes in and out, and it indicates a narrowing of the subglottis, the cartilage right below the vocal cords.
Can you have expiratory stridor?
Stridor can be inspiratory, expiratory, or biphasic; this may aid in determining the anatomic location of the airway obstruction. Inspiratory stridor is more likely to be caused by extrathorasic obstruction to air flow while expiratory stridor is more likely to occur with intrathorasic pathology.
What is respiratory stridor?

What to do for stridor?
Stridor may be a sign of an emergency. Call your provider right away if there is unexplained stridor, especially in a child. In an emergency, the provider will check the person’s temperature, pulse, breathing rate, and blood pressure, and may need to do abdominal thrusts. A breathing tube may be needed if the person can’t breathe properly.
What does stridor sound like in toddler?
Stridor is an abnormal, high-pitched, musical breathing sound. It is caused by a blockage in the throat or voice box (larynx). It is most often heard when taking in a breath. Children are at higher risk of airway blockage because they have narrower airways than adults. In young children, stridor is a sign of airway blockage.
