Clinical InformationClinical

  • Hypercapnia

    a clinical manifestation of abnormal increase in the amount of carbon dioxide in arterial blood.

  • Obstructive Sleep Apnea Syndrome

    a disorder characterized by recurrent episodic disruptions of breathing during sleep. it is caused by the intermittent relaxation of pharyngeal muscles leading to the narrowing or complete blockage of the upper airway. this results in compensatory arousal from sleep to breathe again. an anatomically narrow airway from body habitus or enlarged pharyngeal structures may also predispose to obstruction. clinical presentation usually includes snoring, daytime sleepiness, difficulty concentrating and fatigue. clinical course may progress to chronic hypoxemia with cardiovascular and cerebrovascular sequelae.

Patient EducationClinical

Sleep Apnea

Sleep apnea is a common disorder that causes your breathing to stop or get very shallow. Breathing pauses can last from a few seconds to minutes. They may occur 30 times or more an hour.
