Central Sleep Apnea
Breathing Related Sleep Disorder
People whose breathing is interrupted during their sleep often experience numerous brief arousals throughout the night and do not feel rested even after 8 of 9 hour asleep. These problems are diagnosed as Breathing Related Sleep Disorder. For all of us, the muscles in the upper airway relax during sleep, constricting the passageway somewhat and making breathing a little more difficult. For some unfortunately, breathing is constricted a great deal and may be labored (hypoventilation) or, in the extreme, there may be short periods when they stop breathing altogether, called sleep apnea.
There are three types of apnea, each with different causes, daytime complaints and treatment: Obstructive; Central and mixed Sleep apnea.
About Central Sleep Apnea:
- Wake frequently during the night.
- Tend not to report excessive daytime sleepiness.
- They do not have serious breathing problem
- Difficulty initiating sleep.
- Frequent awakening of problems returning to sleep after awakening.
- Early morning awakening with inability to return sleep.
Causes may include narrow or obstructed airway, obesity and increasing age.
Treatment using continuous positive air pressure (CPAP) machines is the gold standard for Breathing- Related sleep disorder. Weight loss is also often prescribed.
