obstructive sleep apnea syndrome (osas) in childhood is characterized by intermittent partial or complete collapse of the upper airway (obstructive hypopnea or apnea). snoring is the most common and characteristic symptom of osas and it is caused by partial pharyngeal occlusion. therefore, palatine and pharyngeal tonsillar hypertrophy is considered pathologic in subgroups of children and associated with osas23–25. history and physical examination are unable to distinguish between children with osas and primary snoring; however they are useful in selection of those who should be screened for osas in a sleep centre32,33.
children with primary snoring who are referred to sleep centers have higher blood pressure compared to normal children43; however history of snoring is not considered a risk factor for high blood pressure in the general pediatric population43. it is indicated that children with primary snoring are also at risk of developmental and behavioral disorders56. diagnosis of osas in children cannot be established upon history of snoring and physical examination. sleep study in children with severe signs and symptoms can lead to preoperative detection of those who are at higher risk of developing postoperative complications or recessive disease.
the first part entitled “definition and classification of sleep-related breathing disorders in adults. the first organized effort for the classification of sleep disorders was published in sleep in 1999 under the title “diagnostic classification of sleep and arousal disorders”. in limited sleep studies (which does not include eeg), rdi is defined as the number of apneas and hypopneas per hour of sleep recorded. the events of central apnea result in disturbance of normal sleep architecture and appearance of nocturnal arousals, daytime sleepiness or insomnia.
it requires a highly equipped laboratory that meets standard qualifications and it is considered as the gold standard for the diagnosis and of the therapeutic application of cpap or bpap. it is time-saving and cost-effective since the diagnostic study is followed by application of cpap during the same night. they are used for the application and determination of functional parameters of a therapeutic appliance or in order to establish the efficacy of a new treatment method. *1:differential diagnosis and classification of hypopneas as obstructive, central or mixed requires measurement of respiratory effort.
the term obstructive sleep related breathing disorders includes a variety of pathologic conditions ranging from primary snoring and upper airway resistance clinical suspicion of sleep related breathing disorder on the grounds of a well-known predisposing condition unrelated to respiratory system, such as congestive obstructive sleep apnea is the most common sleep-related breathing disorder. it causes you to repeatedly stop and start breathing while you, .
sleep apnea is a sleeping disorder that can lead to serious health problems, such as high blood pressure and heart trouble, if untreated. sleep-related breathing disorders are conditions of abnormal and difficult respiration during sleep, including chronic snoring and sleep suspected osa complicated by other respiratory sleep disorders — complicated osa refers to the presence of medical conditions that could, .
