Talk:Central hypoventilation syndrome

message: A fairly recently discovered function of the hair cells is to transmit information concerning carbon dioxide levels in the blood and relaying this information to the brain to drive normal breathing. A loss of these chemosensitive hair cells can cause death. https://www.audiologyonline.com/releases/ears-may-hold-answers-to-4038

thread_title:  Could inner ear damage also be one of the causes? 

message: I removed the link to  Ondine (play) from see also. I think it is appropriate on Ondine (mythology), but not here, this page is about a medical condition. Both are related to Ondine (mythology) but not really to eachother. --WS 23:31, 30 November 2005 (UTC)

message: Should this article be moved to Congenital Central Hypoventilation Syndrome? rarediseases.about.com suggests that it should, though I wouldn't call that authoritative.  Perhaps Hypoventilation syndrome might be more correct as it covers a broader ranger (see this article as eMedicine.  violet/riga (t) 20:16, 22 January 2006 (UTC)

message: Most people with congenital Ondine's curse do not survive infancy, though they can be kept alive with a ventilator. This seems contradictory - if you can be kept alive, you're surviving. This could use some clarification as to what is meant.--RLent 19:21, 20 June 2007 (UTC)
thread_title:  Clarification 

message: other web sources indicate the condition is highly survivable, and that most people will live productive and near-normal lives.  see, e.g. the cchs family network website at www.cchsnetwork.org, among others.  this is the only place i have seen so far that suggests a high mortality rate in infancy.208.27.203.128 22:59, 20 June 2007 (UTC)
thread_title:  "Prognosis"-accuracy? 

message: Is CCHS the same as congenital central alveolar hypoventilation syndrome? While the ICD-9 code for "Ondine's curse" gets you 348.8 - condition of brain, CCAHS has it's own code - 327.25.--209.7.195.158 (talk) 18:08, 4 June 2008 (UTC)

thread_title:  Long term prospects 

message: CCHS is not uniformly lethal as is suggested in the opening. I have Lo-CCHS (Late onset) and I am very alive at age 65. I may be the eldest currently known to be alive, but I am. I have very long term hypoxic brain pathology and it was not discovered until three years ago by MRI. Because it has appeared so slowly my brain was able to work around it, for the most part. I suffer from 24/7 central "apnea" of the type in CCHS which means it completely disappears during REM sleep. The term "Ondine's Curse" is not at all appropriate to CCHS and is not used to identify the disorder except by the poorly informed. True Ondine's Curse does exist as a medical syndrome and is normally uniformly lethal when it appears, usually due to some form of brain stem damage such as by a stroke. Using this name to identify this syndrome is incorrect and potentially misleading. 
In large part this is because the type of breathing that occurs in CCHS is not a form of apnea and not a total failure to breath, it is hypo-ventilation. Breathing still occurs but is at a minute volume level much too low to support proper oxygenation of the blood. I still breath during the hypo-ventilation episodes which can last an hour and longer but the minute volume I intake can be as low as one tenth of normal. My SpO2 has been measured as low as 73 during an episode, three years ago. I was able to find a way to treat my CCHS which has worked very well. As soon as I discovered what was happening (with the help of doctors) I began using very low level oxygen when sleeping, about 1 litre per minute. I am able to detect my breathing failures while awake so I only need it when sleeping. Low level oxygen raises the level of CO2 in the brain only and causes the faulty brain stem sensors to properly signal breathing cycles. Amazingly, it has been recently determined that I no longer need oxygen. It seems that the brain stem sensors have been somehow recalibrated and I now have few enough periods of hypo-ventilation that my SpO2 never drops below 90 or so. I no longer need to use oxygen and have been off it for two months. It remains to be seen if the recalibration will be permanent.

thread_title: Survival

message: The lead section states that "Congenital cases are very rare", but the causes section contradicts this, saying "CHS is exhibited typically as a congenital disorder". Which is correct? Technically they can both be true, but only if non-congenital cases are also very rare. Hairy Dude (talk) 18:43, 12 November 2018 (UTC)
thread_title:  Rarity 

message: Can anyone think of another photo for this article besides the one of Ondine?  I haven't been able to think of one yet.  However, it's my understanding that CCHS is not referred to as "Ondine's curse" by folks who have this disease or by folks who treat it.  (For example, I don't think the webpage for the CCHS Network, the major advocacy organization for CCHS, mentions Ondine at all.)  One of my family members died of CCHS, and I feel the emphasis given to the Ondine reference (by featuring this photo at the top of the article) is disrespectful and frankly somewhat creepy.  Thanks!

replies: text: The CCHS Overview states that "In recent years this term has been disavowed by the CCHS Community, in favor of CCHS"; their reason being that "[most] individuals with CCHS do not stop breathing altogether, but do not breathe deeply enough to support body functions" [my emphases]. IMO keep the image but make clear that the name is a misnomer rmacd (talk) 01:41, 16 May 2020 (UTC)
