what is stridor

Stridor is a high-pitched, noisy or wheezing sound that occurs during breathing and is typically associated with a partially blocked or narrowed upper airway, such as the larynx or trachea. It can be inspiratory, expiratory, or biphasic, but is most commonly heard during inspiration. Stridor can be caused by various factors, including congenital malformations, infections, or foreign body obstruction. It is important to determine the underlying cause of stridor, as the treatment depends on the specific condition. If a child is experiencing stridor, it is essential to seek medical attention to identify the cause and determine the appropriate course of action
