What is Obstructive Sleep Apnea?
Obstructive Sleep apnea (OSA) is a sleep-related breathing disorder. It occurs when the tissue in the back of the throat collapses, temporarily blocking the airway. When this happens, it blocks the airflow to the lungs decreasing Oxygen levels in the blood signaling to your brain to wake up. It happens so quickly that the sleeper may not even remember the arousal.
