stridor etymology

Etymology

• Late Latin: stridor
• From the Latin verb stridere meaning "to make a creaking or rattling sound"

Meaning

• A harsh, high-pitched, rattling sound caused by obstructed airflow in the respiratory system

Origin

The word "stridor" originates from the Indo-European root ster-, which means "to spread." This root is also the origin of the words "stern" and "star." The Latin verb stridere is derived from this root and is onomatopoeic in nature, imitating the sound of creaking or rattling.

Use in Medicine

In medicine, stridor is used to describe a specific type of abnormal respiratory sound that is caused by obstructed airflow. It is often associated with respiratory conditions that affect the larynx (voice box), trachea (windpipe), or major bronchi (airways).

Types of Stridor

• Congenital stridor: Occurs in newborns due to an underdeveloped or floppy epiglottis
• Infectious stridor: Caused by infections of the upper respiratory tract, such as croup or epiglottitis
• Inflammatory stridor: Associated with inflammation of the airways, such as in asthma or bronchitis
• Paralytic stridor: Results from paralysis or weakness of the muscles involved in breathing
• Tracheal stridor: Caused by a narrowing of the trachea due to a tumor or foreign body
