sleep related hypoventilation

in this review the clinical management of chronic hypoventilation in neuromuscular disease will be considered and then compared with that in obesity hypoventilation syndrome. differences in the pattern of sleep disordered breathing tend to follow from the distribution of respiratory and bulbar muscle involvement. as discussed above, niv is indicated in patients with daytime hypercapnia and symptomatic nocturnal hypoventilation in the absence of raised daytime pco2. health-related quality of life was improved in those randomised to niv and several patients in the control group had unplanned admissions for acute ventilatory decompensation. there are reports of the use of high flow oxygen therapy in children with osa [10], and in those who fail continuous positive airway pressure (cpap); however, this is unlikely to be first-line therapy and should be used with caution, and careful monitoring of pco2.

the combination of inspiratory muscle assistance with niv and expiratory muscle assistance with cough insufflation-exsufflation was shown to be more effective than tracheostomy ventilation in reducing pulmonary morbidity in duchenne muscular dystrophy patients [12] and this noninvasive approach is usually preferred by patients [13]. unsurprisingly the prevalence of ohs is increasing as global levels of obesity rise with an estimated prevalence of 0.3–0.4% in the general population and 10–20% in those with sleep disordered breathing. in eucapnic individuals and those with osa the acute hypercapnia which ensues from a brief apnoea or hyponoea is rapidly reversed by augmented tidal volume in the following few breaths. consecutive patients were treated with a similar niv protocol based on the finding of respiratory acidosis, dyspnoea and respiratory rate of ≥25·min−1. however, ventilatory support is not a “cure” and it is not clear whether the cardiovascular consequences of these disorders can be reversed. note: we only request your email address so that the person you are recommending the page to knows that you wanted them to see it, and that it is not junk mail.

these issues are not the result of another sleep disorder. risk factors are related to the subtype of the disorder that the person has. those with a medical condition including lung disorders, spinal injuries, or brain/muscle disorders may also be at higher risk.

as with the risk factors, the conditions that also occur are typically the ones that are causing the sleep disorder including lung and respiratory disorders, spinal injuries, brain/muscle disorders, and long term use of opioids or benzodiazepines. for example, with a lung or respiratory disorder, that could include stopping smoking, supplemental oxygen or medication to reduce symptoms. if a substance is causing it, treatment could include drug treatment or self-help groups, such as alcoholics anonymous or narcotics anonymous.

hypoventilation during sleep may be associated with poor sleep quality, excessive daytime sleepiness and morning headaches. however, a relevant portion of in sleep-related hypoventilation, psg demonstrates episodes of decreased respiration associated with elevated levels of carbon dioxide. sleep-related hypoventilation is a breathing-related disorder that interrupts normal sleep. this condition may be diagnosed when all other, .

sleep-related hypoventilation is breathing that is not sufficient during sleep. breathing is either too shallow or too slow. sleep-related hypoventilation is a category of disorders that have different underlying causes. overall, these disorders lead to an increase of carbon dioxide in the blood. while some people exhibit hypoventilation as early as childhood, it’s more common to develop due to obesity, an underlying medical disorder, or drug use. people with chronic obstructive pulmonary disease (copd) are significantly more likely6 to have sleep-related hypoventilation. signs and symptoms of srh are related to the higher levels of carbon dioxide in the blood and to sleep disturbance. they include: morning headaches, restless there are a number of definitions of nocturnal hypoventilation, for example carbon dioxide tension (pco2) >50 mmhg for more than 5% study time, a 10 mmhg rise what is sleep-related hypoventilation? in this disorder, a person has decreased breathing during sleep, which leads to an increase in blood carbon dioxide, .
