Stertorous
Stertorous Breathing: Definition, Causes, and Clinical Implications[edit | edit source]
Stertorous breathing, a term rooted in clinical medicine, refers to a distinctive respiratory sound reminiscent of heavy snoring or gasping. Often indicative of partial upper airway obstruction, this sound provides clinicians with essential cues about a patient's respiratory health and potential underlying conditions.
Etymology and Definition[edit | edit source]
Derived from the Latin word “stertor,” which means "to snore," stertorous describes a specific type of snoring or gasping sound evident during respiration. This sound is characterized by its low pitch, non-musical quality, and confinement primarily to the inspiratory phase[1].
Pathophysiology[edit | edit source]
Stertorous breathing arises from:
Partial obstruction of the upper airway, specifically above the level of the larynx. Vibrations in the tissues of the naso-pharynx, pharynx, or soft palate. This distinguishes stertorous breathing from stridor, which is caused by turbulent airflow either within the larynx or below it[2].
Clinical Significance[edit | edit source]
Identifying stertorous breathing is crucial as it often signals:
- Airway Obstruction: This sound can indicate blockages, like those caused by enlarged tonsils, adenoids, or even tumors.
- Post-Seizure State: Stertorous respiration is often audible in patients recovering from a tonic-clonic seizure during the post-ictal phase, suggesting that the patient is transitioning from the seizure activity to a recovery state[3].
- Sleep-Related Disorders: Conditions like sleep apnea might manifest initially as stertorous breathing, prompting further investigation[4].
- Narcotic Overdose: Patients who have overdosed on narcotics can also exhibit stertorous breathing due to depressed respiratory drive[5].
Conclusion[edit | edit source]
Stertorous breathing provides a clear auditory clue to potential respiratory or neurological conditions, necessitating prompt clinical evaluation and intervention. Recognizing this sound can be instrumental in ensuring patient safety and guiding treatment decisions.
