Let’s find out about stridor, its causes, and what you can do about it.

What Is Stridor?

Also called extrathoracic airway obstruction and musical breathing, stridor sound is breathing that is unusually noisy. What does stridor sound like? It’s a high-pitched, wheezing sound. The stridor sound may also vibrate like a low whistle and is loud enough to hear without the aid of a stethoscope. Check here for stridor lung sounds audio.

There are three types of stridor sounds:

  • Inspiratory – This is when you only hear the noise as your child inhales. Inspiratory means there is a problem with the area or tissue above the vocal cords.
  • Expiratory – Opposite to the previous type, you only hear sounds when your baby exhales. Expiratory is indicative of something blocking the windpipe.
  • Biphasic – This is a combination of the previous two. With biphasic stridor, you can hear the noise when your child both inhales and exhales. Biphasic means that the cartilage near the vocal cord has narrowed.

What Causes It?

There are several causes of stridor breathing sounds, including:

  • Laryngomalacia – This is a congenital condition that is the most common culprit of stridor lung sounds in infants and young children. Here, the tissues of the larynx or voice box soften. The membrane may have malformation and thus partially block the airway.
  • Foreign object – Babies can be curious. Because of this, a foreign object may become lodged in your child’s throat, airway, or nose. If this is the cause, the stridor sound is often temporary. It typically goes away once you remove the object.
  • Inflammation – Musical breathing can also occur from inflammation of the airway, throat, or lymph nodes. It may be due to an infection, an allergic reaction, croup, bronchitis, epiglottitis, and even tonsillitis. Croup is the leading cause of acute stridor.
  • Trauma – Trauma to the airway or vocal cords can also lead to noisy breathing. It can be from a throat surgery or an accident leading to a fracture in the neck.
  • Harmful substances – Inhaling smoke and swallowing chemicals can damage the throat and airway.

Is It Dangerous?

How dangerous stridor breath sounds are will depend on its cause. Generally, you should see a health professional if you hear your child experiencing this.

Some cases are considered a medical emergency and need immediate care. One of such cases is if there is something lodged in your child’s throat, causing them to choke. Allergies leading to anaphylaxis also require urgent care. Other instances of inflammation may also be life-threatening as they impair breathing.

Signs to look out for include bluish lips or skin, difficult or strained breathing, lethargy, and weight loss.

Laryngomalacia is a different case, however. It is common and rarely life-threatening. It often becomes noticeable in infants around 4 to 7 months of age. For most kids, they outgrow this by the age of 2, and rarely will it require medical attention.


How Is It Treated?

For stridorous breath sounds, your child may need medical treatment. Your physician or pediatrician may perform one of the following:

  • They may refer you to a throat or nose specialist.
  • Provide an injection or oral medicine for allergies or inflammation in general.
  • Hospitalize and monitor your child. In severe cases, performing surgery may be necessary (although this is rare).

In summary, what do you need to do immediately for stridor breathing sound? Call your doctor. Even if stridor lung sound runs in the family, it’s likely that you won’t know its cause. Ask your doctor about stridor sounds and other medical concerns. Better safe than sorry.
