Filter by:assess the relationship between obstructive sleep apnea and endocrine, inflammatory, and metabolic bio-markers in consecutively enrolled adult male patients with a clinical suspicion of obstructive sleep apnea.
The primary study objective is to investigate sensitivity and specificity of a wrist sensor pulse oximeter (the Oxitone Medical Oxitone 1000M device) to screen for obstructive sleep apnoea. This study will involve thirty participants attending a sleep centre suspected of suffering from obstructive sleep apnoea (case finding screening). The secondary objective is to assess patient convenience with the screening procedure.
Obstructive Sleep Apnea-Hypopnea Syndrome (OSAHS) is a condition where the upper airway partially collapses and closes. This can lead to sleep problems including low oxygen levels, poor sleep, elevated carbon dioxide levels in the blood, and activation of the sympathetic nervous system. Results from having disrupted sleep may be excessive daytime sleepiness along with behavioral, functional, cardiovascular and cognitive dysfunction. Continuous Positive Airway Pressure (CPAP) is the most effective treatment for OSAHS. CPAP stabilizes the airway and prevents instability and collapse. Other forms of positive airway pressure that are approved for the treatment of OSAHS include automatically adjusting CPAP, Bi-level Positive Airway Pressure (BiPAP), and automatically adjusting BiPAP. Automatically adjusting CPAP (Auto CPAP) evaluates the airflow pattern and adjusts pressure to optimize airflow. AutoSV (Auto Servo Ventilation) is a mode of positive airway pressure used to treat obstructive and complex central sleep apnea. In the prior study, the investigators found that the Auto S7 device led to more positive ventilation outcomes. Specifically, there was prolongation of QTc interval (the calculated time from the Q wave to the end of the T wave) and a tendency for greater premature ventricular contractions. The mechanistic basis for this could be attributable to excessive ventilation and related pro-arrhythmic effects of hypocapnia, though the investigators had not performed measures (partial pressure of CO2 (PaCO2) to detect this. In the current study, the investigators would like to investigate the hypothesis that the S7 device leads to lower PaCO2 levels than other devices, and whether these effects are augmented in individuals with complex sleep apnea in the setting of systolic heart failure.
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
The aim of the study is to assess the effect of adenotonsillectomy on level of asthma control in preschool children with obstructive sleep apnea.
The primary aim of this study is to research the effect of intubation without muscle relaxant on post-operative recovery conditions in patients with OSAS (obstructive sleep apnea syndrome). Our secondary aim is to research the hemodynamic parameters in intraoperative period and complications such as sore throat and laryngospasm voice limitation in the postoperative period.
Aim of the study To determine the exact role of hyoid bone suspension surgery in splinting lateral pharyngeal wall in the era of the lateral pharyngoplasty
The oral appliances (OAs) are considered to be an effective treatment modality for snoring and various forms of obstructive sleep apnea syndrome (OSAS). They facilitate the displacement of the mandible anteriorly and widen the upper airway during sleep. Lateral cephalometry has been used for the two-dimensional evaluation of upper airway form with several limits.The purpose of present study is to investigate an accurate three-dimensional (3D) volume analyses with cone beam computed tomography (CBCT) scans to confirm the effects of OAs on the upper airway in patients with OSAS.The investigators aim to enroll twenty-four patients with mild,moderate or severe OSAS, intolerant to continuous positive air pressure therapy and rejection a surgical approach,who will be treated with adjustable customized OAs and evaluated with CBCT and polysomnography. Upper airway form was examined and the volume was measured in two different areas. Specific planes have been considered to match the data and calculate the benefit obtained with therapy.
The purpose of this study is to determine whether early diagnosis of OSA and initiation of and adherence to CPAP therapy in patients hospitalized for chronic obstructive pulmonary disease reduce 30-day hospital readmission rates.
The aim of this study is to examine whether voice acoustic properties has an influence on sleep apnea. Sleep apnea syndrome is defined as a sudden stop of more than ten seconds multiple times during sleep. The syndrome is common especially among men and occurs in 2%-4% of the population aged 30-60. The syndrome diagnosis is performed by an ENT (Ear, Nose and Throat) physician. The diagnosis is based on evaluation of anatomical structures in the sound path (nose and throat, jaw, pharynx and oral cavity) and a Polysomnography (PSG) test which quantifies the number and duration of breathing pauses during night sleep and additional parameters that monitor sleep. The syndrome has many negative consequences for those who suffer from it, including fatigue , lack of concentration, hypertension, diabetes ,heart disease, stroke and even death. Therefore, early diagnosis is important.
