Cardiopulmonary Exercise Test in Patient With Obstructive Sleep Apnea

Obstructive Sleep Apnea

Obstructive sleep apnea (OSA) can be described as a condition characterized by repetitive obstruction of the upper airway resulting in oxygen desaturation and awakening from sleep, loud snoring, and increased daytime sleepiness . Many studies have shown that a link exists between OSA and cardiovascular disease, chronic heart failure ischemia, hypertension, obesity, and impaired glucose tolerance . A number of factors are likely to play role in development of clinical OSA syndrome (OSAS) ranging from upper airway anatomy to central respiratory control mechanisms. The pathophysiology of OSA is unclear and complex. Several previous studies have explored pulmonary function in the OSAS patients Interestingly, OSAS has been found to be highly correlated with lower airway obstruction, although it is originally defined as an upper airway disease

OSA in Children Referred for Adenotonsillectomy

Obstructive Sleep Apnea

In children with OSA (Obstructive sleep apnea) adenotonsillectomy is regarded as the first choice of treatment. Studies in recent years have shown that the procedure does not always have the expected effect. Children with OSA are at greater risk for complications from the procedure. There is disagreement regarding the need for sleep studies in children prior to surgery in order to verify an OSA diagnosis. Today less than 10% of these children have polysomnography (PSG). The main purpose of this study is to describe the prevalence of OSA among children referred for adenotonsillectomy. The investigators will also examine these children prior to and six months after surgery to assess their sleep pattern and quality of life. The project outcome aims to improve the precision and quality of diagnosis and the short and long term effects of treatment of children with OSA.

Sleep Apnea SyndromesObstructive2 more

A total of 400 participants will be recruited: 200 patients with suspected OSAS will be recruited from the sleep clinic (OSAS group), 100 patients diagnosed with dizziness will be recruited from the ENT clinic (Dizziness group). In addition, 100 patients with no dizziness and no evidence for OSAS will be recruited from both the sleep clinic and the ENT clinic (controls). Informed consents will be completed by all participants. ). In order to assess the effect of treatment of OSAS on dizziness -patients with the diagnosis of OSAS will complete validated questionnaires regarding sleep, dizziness and eustachian tube function 3 months following initiation of treatment with CPAP
