Detailed explanation-1: -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.

Detailed explanation-2: -Generally, an inspiratory stridor suggests airway obstruction above the glottis while an expiratory stridor is indicative of obstruction in the lower trachea. A biphasic stridor suggests a glottic or subglottic lesion. Laryngeal lesions often result in voice changes.

Detailed explanation-3: -Less musical sounding than a wheeze, stridor is a high-pitched, turbulent sound that can happen when a child inhales or exhales. Stridor usually indicates an obstruction or narrowing in the upper airway, outside of the chest cavity.

Detailed explanation-4: -A vital clinical sign is noisy breathing, which can be described as ‘stertor’ or ‘stridor’. ‘Stertor’ is noisy breathing which occurs above the larynx. ‘Stridor’ is noisy breathing that occurs at the level of the larynx or below.

Detailed explanation-5: -The main sign of stridor is a high-pitched whistle that can sound like a squeak when you breathe in or out. Depending on the cause, you might experience additional symptoms that could include: Coughing.
