Central hypoventilation syndrome (CHS) is a sleep-related breathing disorder that causes ineffective breathing, apnea, or respiratory arrest during sleep (and during wakefulness in severe cases). CHS can either be congenital (CCHS) or acquired (ACHS) later in life.
Hypopnea during sleep is classed as a sleep disorder. With moderate to severe hypopnea, sleep is disturbed such that patients may get a full night's sleep but still not feel rested. The disruption in breathing causes a drop in blood oxygen level, which may in turn disrupt the stages of sleep.
Hypoventilation (also known as respiratory depression) occurs when ventilation is inadequate (hypo meaning "below") to perform needed respiratory gas exchange. [1] By definition it causes an increased concentration of carbon dioxide ( hypercapnia ) and respiratory acidosis .
Hormonal changes during pregnancy and during and after menopause can also increase your risk of sleep apnea. Health conditions. H eart and kidney failure can cause a build-up of fluid in your neck ...
Sleep apnea is a serious medical condition that causes interruptions in your sleep leading to a wide range of symptoms. Learn more about the condition and how to get diagnosed.
Sleep deprivation may represent a final common pathway in the genesis of mania, [152] and manic patients usually have a continuous reduced need for sleep. [153] The symptoms of sleep deprivation and those of schizophrenia are parallel, including those of positive and cognitive symptoms. [154]
[6] Central hypoventilation syndrome is caused by certain receptors in the brain failing to recognize changes in carbon dioxide levels during sleep, leading to a low breathing rate and low blood concentration of oxygen. Some of the causes of this disease are sudden onset obesity or spinal cord surgery.
The typical screening process for sleep apnea involves asking patients about common symptoms such as snoring, witnessed pauses in breathing during sleep and excessive daytime sleepiness. [19] There is a wide range in presenting symptoms in patients with sleep apnea, from being asymptomatic to falling asleep while driving. [ 19 ]
