Stridor is a harsh, high-pitched respiratory sound, often described as a wheeze, that results from turbulent airflow in the upper airway. This sound arises due to partial obstruction of the trachea or larynx, typically during inhalation but sometimes during exhalation. The obstruction can stem from various causes, including inflammation, foreign bodies, tumors, or vocal cord dysfunction. Identifying stridor is crucial because it often indicates a serious underlying condition that requires prompt medical evaluation and intervention to prevent respiratory distress or complete airway blockage. Careful assessment of the stridor's characteristics – timing (inspiratory, expiratory, or biphasic), pitch, and loudness – can provide valuable clues to its cause.
