Different Types of Sleep Apnea: Understanding CSA and OSA

Sleep apnea is a condition that involves the periodic cessation of breathing while a person is asleep. There are two primary types of sleep apnea: obstructive sleep apnea (OSA) and central sleep apnea (CSA). At Snoring & Sleep Apnea Center in Seattle, WA, Dr. Robert L. Horchover and his team offer a comprehensive menu of practical solutions for men and women suffering from sleep apnea, allowing them to enjoy healthier and more fulfilling lives.

The Difference Between CSA and OSA

Obstructive sleep apnea occurs when the muscles of the throat relax too fully during sleep, failing to support the tissues of the soft palate in the mouth. The patient affected by OSA struggles to inhale, but the airway is blocked. These instances of apnea, or breathing cessation, occur continuously throughout the night.

Central sleep apnea, or CSA, is considerably less prevalent than OSA. CSA also involves lapses in breathing as the patient sleeps, but this is not due to an issue with the airway. A patient suffering from central sleep apnea fails to breathe correctly and continuously because the brain simply does not send the appropriate signals to the respiratory system. Some patients suffer from both CSA and OSA simultaneously; a comprehensive sleep study can determine which condition is responsible for the numerous pauses in breathing at night.

Dr. Horchover and his experienced team will work with you to determine which treatment method best suits your unique situation and lifestyle.
