What is Sleep Apnea?
Sleep apnea is a serious sleep disorder that occurs when a person’s breathing is interrupted during sleep. People with untreated sleep apnea stop breathing repeatedly during their sleep, sometimes hundreds of times. This means the brain — and the rest of the body — may not get enough oxygen.
Obstructive Sleep Apnea (OSA)
The more common of the two forms of apnea is caused by a blockage of the airway, usually when the soft tissue in the back of the throat collapses during sleep.
Central Sleep Apnea: Unlike OSA, the airway is not blocked, but the brain fails to signal the muscles to breathe due to instability in the respiratory control center.
