inspiratory stridor

Inspiratory stridor is a high-pitched sound or noise that occurs when breathing in. It happens when there is an obstruction or narrowing in the upper airway, such as the throat, voice box, or windpipe. This narrowing makes air movement turbulent, producing the noisy sound during inhalation. Stridor can be caused by various conditions like infections, allergies, inflammation, swelling, or structural abnormalities. It is often a sign that there is airway difficulty, which may require medical evaluation to identify and treat the underlying cause to ensure breathing remains safe and comfortable.
