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.
[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.
ROHHAD was first described in 1965, and this was believed to be the first reported instance of hypoventilation presenting alongside hypothalamic dysfunction. [2] ROHHAD had often been mistaken for congenital central hypoventilation syndrome, until the distinction was made by Ize-Ludlow et al. in 2007.
Daytime hypopnea events, however, are mostly limited to those with severely compromised respiratory muscles, as occurs in certain neuromuscular diseases or compromised central respiratory drive, as occurs in conditions such as acquired or congenital central hypoventilation syndrome (ACHS or CCHS). Daytime hypopnea can also cause a drop in blood ...

This is a shortened version of the fifth chapter of the ICD-9: Mental Disorders.It covers ICD codes 290 to 319.The full chapter can be found on pages 177 to 213 of Volume 1, which contains all (sub)categories of the ICD-9.
As a side effect of medicines or recreational drugs, hypoventilation may become potentially life-threatening.Many different central nervous system (CNS) depressant drugs such as ethanol, benzodiazepines, barbiturates, GHB, sedatives, and opioids produce respiratory depression when taken in large or excessive doses, or mixed with other depressants.
Central sleep apnea (CSA) or central sleep apnea syndrome (CSAS) is a sleep-related disorder in which the effort to breathe is diminished or absent, typically for 10 to 30 seconds either intermittently or in cycles, and is usually associated with a reduction in blood oxygen saturation.
