Sleep apnea is a condition where the airway repeatedly becomes entirely blocked, preventing breathing. The word “apnea” means “no breathing.” You might wake up enough to gasp for air and then fall back to sleep. In the morning you often have no memory of these incidents.
The official definition of sleep apnea is blocked breathing five or more times per hour for at least ten seconds each time. The average time is 22 seconds. Try holding your breath for 22 seconds — good luck! The lack of breathing causes a significant drop in blood oxygen levels. Although there are three types of sleep apnea, the most common one is called Obstructive Sleep Apnea (OSA).Take the Test
