What sound indicates partially obstructed airflow in a patient?

Stridor is a high-pitched, wheezing sound that is typically a sign of partially obstructed airflow, especially in the upper airway. It occurs due to turbulent airflow in the larynx or trachea, often resulting from narrowing or blockage. This sound is particularly associated with conditions such as croup, epiglottitis, or anaphylactic reactions, which can lead to swelling or other forms of obstruction in the airway.

When a patient exhibits stridor, it usually indicates that there is a need for immediate assessment and potential intervention, as the compromised airway can lead to respiratory distress or failure if not addressed promptly. Understanding this sound and its implications is crucial for any healthcare provider, particularly in emergency settings, to ensure that proper care is administered swiftly to relieve the obstruction and secure the airway.
