The practical purpose of diagnostic assessment in most cases of obstructive sleep apnea is to predict which patients have symptoms that will improve on treatment. We measured the accuracy with which clinicians make this prediction using polysomnography compared with oximeter-based home monitoring. Patients referred to a sleep center with suspicion of symptomatic obstructive sleep apnea were ran...

BACKGROUND The British Thoracic Society report on the diagnosis and treatment of the sleep apnoea/hypopnoea syndrome (SAHS) suggests that, if the pulse oximetry baseline oxygen saturation is above 90%, then 15 4% oxygen desaturation/hour in bed will diagnose SAHS requiring treatment. The diagnostic outcome of applying these guidelines has been studied. METHODS One hundred patients referred to...

BACKGROUND Increasing referral numbers make the development of simplified accurate methods of diagnosing the sleep apnoea/hypopnoea syndrome highly desirable. The accuracy of one such system--the ResCare Autoset--has been examined. METHODS Thirty one consecutive patients assessed by polysomnography had simultaneous monitoring of their respiratory pattern using the Autoset system. The Autoset ...

BACKGROUND Prior studies report a high incidence of airway complications in patients with Robin sequence following palatoplasty. The authors' institution uses polysomnography to assess risk of airway compromise before palatoplasty in Robin sequence. This study compares airway complications in Robin sequence to cleft palate only using this screening airway protocol and identifies risk factors fo...

OBJECTIVES/HYPOTHESIS To determine if supraglottoplasty (SGP) is effective in reversing abnormal respiratory parameters in children with laryngomalacia and obstructive sleep apnea (OSA). STUDY DESIGN Retrospective case series at a tertiary referral children's hospital. METHODS Ten patients with laryngomalacia and OSA as documented by polysomnography underwent SGP between 2005 and 2007. Data...

The present study assessed the usefulness of home cardiorespiratory polygraphy as an alternative to overnight polysomnography for the diagnosis of sleep-disordered breathing in heart failure. A total of 75 patients with chronic stable heart failure due to systolic dysfunction (left ventricular ejection fraction < or =45%) underwent polysomnography at the Virgen del Rocio Hospital and cardioresp...

OBJECTIVES While respiratory distress is accepted as the only indication for diaphragmatic plication surgery, sleep disorders have been underestimated. In this study, we aimed to detect the sleep disorders that accompany diaphragm pathologies. Specifically, the association of obstructive sleep apnea syndrome with diaphragm eventration and diaphragm paralysis was evaluated. METHODS This study ...

Previous studies indicate that subjectively reported and objectively measured sleep abnormalities at baseline can increase the risk of relapse in treated alcoholics. However, previous studies did not include both subjective and objective sleep measures in the same group of patients. We utilized polysomnography and the Sleep Disorders Questionnaire to determine if baseline polysomnography increa...

UNLABELLED Polysomnography is the goldstandard exam for child OSAS. When possible, polysomnography clearly distinguishes between those with isolated primary snoring and patients with sleep apnea (obstructive, central and mixed). The most common cause of OSAS in childhood is adenotonsillar hypertrophy. Laryngomalacia is the most common cause of stridor in childhood, though its physiopathology re...

The advantage of being a National Referral Centre for patients with suspected obstructive sleep apnoea (OSA) was used to seek clinical factors predictive of OSA, and thus determine if the number of polysomnography tests required could be reduced. Patients were mainly primary referrals, from an island population of 3.5 million. Two hundred and fifty consecutive patients underwent clinical assess...
