What is some background information about Stridor?

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. It must be treated right away to prevent the airway from becoming completely closed.

The airway can be blocked by an object, swollen tissues of the throat or upper airway, or a spasm of the airway muscles or the vocal cords.

What are the causes of Stridor?

Common causes of stridor include:

  • Airway injury
  • Allergic reaction
  • Problem breathing and a barking cough (croup)
  • Diagnostic tests such as bronchoscopy or laryngoscopy
  • Epiglottitis, inflammation of the cartilage that covers the windpipe
  • Inhaling an object such as a peanut or marble (foreign body aspiration)
  • Swelling and irritation of the voice box (laryngitis)
  • Neck surgery
  • Use of a breathing tube for a long time
  • Secretions such as phlegm (sputum)
  • Smoke inhalation or other inhalation injury
  • Swelling of the neck or face
  • Swollen tonsils or adenoids (such as with tonsillitis)
  • Vocal cord cancer
How do I perform a home exam for a Stridor?

Follow your health care provider's advice to treat the cause of the problem.

When should I contact a medical professional for Stridor?

Stridor may be a sign of an emergency. Call your provider right away if there is unexplained stridor, especially in a child.

What should I expect during a doctor appointment?

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.

After the person is stable, the provider may ask about the person's medical history, and perform a physical exam. This includes listening to the lungs.

Parents or caregivers may be asked the following medical history questions:

  • Is the abnormal breathing a high-pitched sound?
  • Did the breathing problem start suddenly?
  • Could the child have put something in their mouth?
  • Has the child been ill recently?
  • Is the child's neck or face swollen?
  • Has the child been coughing or complaining of a sore throat?
  • What other symptoms does the child have? (For example, nasal flaring or a bluish color to the skin, lips, or nails)
  • Is the child using chest muscles to breathe (intercostal retractions)?

Tests that may be done include:

  • Arterial blood gas analysis
  • Bronchoscopy
  • Chest CT scan
  • Laryngoscopy (examination of the voice box)
  • Pulse oximetry to measure blood oxygen level
  • X-ray of the chest or neck
