a high frequency of apneas or hypopneas during sleep may interfere with restorative sleep, which – in combination with disturbances in blood oxygenation – is thought to contribute to negative consequences to health and quality of life. temporary spells of osa syndrome may also occur in individuals who are under the influence of a drug (such as alcohol) that may relax their body tone excessively and interfere with normal arousal from sleep mechanisms. the two types of osa in children can results in different morbidities and consequences. at the beginning of sleep, a patient is in light sleep and there is no tone loss of throat muscles. clearly, gravity and loss of tongue and throat tone as a person enters deep sleep are clear and obvious factors contributing to osa developing.  allergic rhinitis and asthma have also been shown to be implicated in the increased prevalence of adenotonsillar hypertrophy and osa. the palate is both the roof of the mouth and the floor of the nose.  finally, patients with osa are at an increased risk of many perioperative complications when they are present for surgery, even if the planned procedure is not on the head and neck.  obesity also has an impact on the consequences of osa and lead to different manifestations or severity. the variability of the blood pressure has been shown to be correlated with the severity of the symptoms such as the frequency of the apnea and hypopnea.
 due to all the consequences and symptoms it generates, osa in children lead to a significant decrease in the quality of life, the decrease being even higher when obesity is present.  nevertheless, osa in adults also implies a large scope of adverse and serious consequences, the latter leading to higher mortality amongst osa patients.  osa is often linked with hypertension as it induces an increase in sympathetic activity that can lead to the elevation of blood pressure.  in osa patients with psychiatric disorders, it is crucial to treat the osa as it may reduce the psychiatric symptoms.  according to the american association of sleep medicine, daytime sleepiness is determined as mild, moderate and severe depending on its impact on social life.  to grade the severity of sleep apnea, the number of events per hour is reported as the apnea-hypopnea index (ahi).  8% of people who use cpap devices stop using them after the first night, and 50% of people with moderate to severe osa stop using their devices in the first year. surgical treatments to modify airway anatomy, known as sleep surgery, are varied and must be tailored to the specific airway obstruction needs of a patient.  evidence is insufficient to support the use of medications to treat obstructive sleep apnea.  in severe and prolonged cases, increased in pulmonary pressures are transmitted to the right side of the heart.  the prevalence of osa with daytime sleepiness is thus estimated to affect 3% to 7% of men and 2% to 5% of women, and the disease is common in both developed and developing countries.
obstructive sleep apnea is the most common sleep-related breathing disorder. it causes you to repeatedly stop and start breathing while you obstructive sleep apnea. obstructive sleep apnea occurs when the muscles that support the soft tissues in your throat, such as your tongue and obstructive sleep apnea is when something blocks part or all of your upper airway while you sleep. your diaphragm and chest muscles have to, central sleep apnea, central sleep apnea, can sleep apnea kill you, osa meaning.
how do i know i have osa? the gold standard for diagnosis is a polysomnography (psg), or, sleep study. this test is performed while the patient is asleep at a sleep laboratory, and monitors brain waves, blood oxygen levels, heart rate and breathing, as well as eye and leg movements. congestive heart failure, high blood pressure, type 2 diabetes and parkinson’s disease are some of the conditions that may increase the risk of obstructive sleep apnea. polycystic ovary syndrome, hormonal disorders, prior stroke and chronic lung diseases such as asthma also can increase risk. in adults, the most common cause of obstructive sleep apnea is excess weight and obesity, which is associated with the soft tissue of the mouth and throat. during sleep, when throat and tongue muscles are more relaxed, this soft tissue can cause the airway to become blocked. the previously mentioned cardiovascular consequences of osa, including atrial fibrillation, heart failure, and hypertension, all can lead to stroke. however, osa in itself seems to lead to an increased risk for stroke independent of these other factors. obstructive sleep apnea is a respiratory disorder that is found in both children and adults. those who exhibit it, experience either complete or obstructive sleep apnea (osa) is a disorder caused by the repetitive collapse of the upper airway during sleep. it is the most commontrusted source obstructive sleep apnea (osa) is the most common sleep-related breathing disorder and is characterized by recurrent episodes of complete or partial, . the most common signs and symptoms of osa include:snoring.daytime sleepiness or fatigue.restlessness during sleep, frequent nighttime awakenings.sudden awakenings with a sensation of gasping or choking.dry mouth or sore throat upon awakening.
