Is stridor an emergency?

Key Points. Inspiratory stridor is often a medical emergency. Assessment of vital signs and degree of respiratory distress is the first step. In some cases, securing the airway may be necessary before or in parallel with the physical examination.

What is a common example of 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.

Poultry and Avian Diseases Infectious laryngotracheitis is a respiratory disease of domestic fowl that is caused by Gallid herpesvirus 1 (Iltovirus: ILT-like virus) (King et al., 2012a). The disease is observed mainly in young male birds of heavy breeds between 3 and 9 months of age.

Is stridor a sign of respiratory distress?

Stridor is always a symptom or sign of underlying disease. An acute onset of stridor always indicates partial obstruction of the airway and a chance of a life-threatening emergency situation. Careful history and examination of the respiratory system gives an idea of the degree of obstruction.
