What does stridor mean in medical terms?

What does the presence of stridor indicate?

Stridor is a high-pitched, wheezing sound caused by disrupted airflow. Stridor may also be called musical breathing or extrathoracic airway obstruction. Airflow is usually disrupted by a blockage in the larynx (voice box) or trachea (windpipe). Stridor affects children more often than adults.

How stridor is caused?

Stridor is a high-pitched sound that is usually heard best when your child breathes in (known as “inspiration”). It’s usually caused by an obstruction or narrowing in your child’s upper airway.

How do you describe stridor?

Stridor is noisy breathing that occurs due to obstructed air flow through a narrowed airway. Stridor breathing is not in and of itself a diagnosis, but rather is a symptom or sign that points to a specific airway disorder.

What is crowing breathing?

Stridor is a continuous, high-pitched, crowing sound heard predominantly on inspiration. The cause of this sound is generally the partial obstruction of the larynx or trachea. Stridor may be heard in conditions such as croup and foreign body obstruction.

Can stridor be caused by allergies?

Patients without fever or symptoms of upper respiratory infection may have an acute allergic reaction or aspirated foreign body. Acute allergic reaction severe enough to cause stridor usually has other manifestations of airway edema (eg, oral or facial edema, wheezing) or anaphylaxis (itching, urticaria).

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 should include:

  • Oxygen (humidified if possible)
  • Dexamethasone oral (unless swallowing problems then IV) 8mg twice daily (morning and lunchtime) if no contraindications and add in gastroprotection if appropriate (e.g. omeprazole oral 20mg once daily or lansoprazole 30mg once daily if no contraindications).

Is wheeze inspiratory or expiratory?

There are two main types of wheezing — inspiratory (when you inhale) and expiratory (when you exhale). It’s easier to hear expiratory wheezing because your airways narrow more during this breathing phase. Sometimes, expiratory wheezing is loud enough to hear on its own.

What is anuria?

What is anuria? Anuria or anuresis occurs when the kidneys aren’t producing urine. A person may first experience oliguria, or low output of urine, and then progress to anuria. Urination is important in removing both waste and excess fluids from your body.

What happens if anuria is not corrected?

Cessation of the production of urine by the kidneys. Anuria is always very serious, unless of brief duration. Uncorrected anuria leads to a build-up of toxic waste material in the blood and eventual death. n lack of urination or urine production of less than 100 ml per day.

What does it mean when a baby has a short stridor?

Stridor in infants usually means your baby was born with a problem that causes partial blockage of their airway. Laryngomalacia is the most common. It’s when the tissue around your vocal cords is loose and floppy. It usually isn’t serious and goes away on its own in about 18 months.
