Types of Sleep Apnea
Sleep apnea occurs in three forms; Central Sleep Apnea (CSA), Obstructive Sleep Apnea (OSA) and Mixed Sleep Apnea.
Of the three, OSA is the most common.
Central Sleep Apnea is rare but sometimes occurs in persons who have suffered a head
injury or stroke. CSA takes place in a region of the brain where the nerves that regulate
breathing no longer function normally and cause breathing to be impaired. It occurs
because the brain fails to instruct the body to breath. The person can breathe, but doesn’t.
During an episode of Obstructive Sleep Apnea (OSA) the upper airway repeatedly collapses
during sleep, preventing air from reaching the lungs. Breathing usually resumes with a loud
gasp, snort, or body jerk. These episodes can occur many times during the night and the
danger increases as the number of events escalate.
OSA episodes also interfere with a sound night’s rest which is essential for the body and
mind to function efficiently. Loss of oxygen to certain vital organs can result in heart attack
and stroke among other problems. A new research paper even suggests a link between
hearing loss and sleep apnea.
The final form is Mixed Sleep Apnea which occurs when a person experiences both central and obstructive apnea. This is extremely rare.
