Filter by:This observational study in a real-world community was designed to perform epidemiological investigation and assess effect of CPAP intervention of obstructive sleep apnea.
Obstructive sleep apnea syndrome (SAOS), very commonly associated with obesity, induces major disturbances in sleep architecture. The hypotheses in this work are twofold: on the one hand, the SAOS could generate pain perception disorders in a population already affected by the mechanical weight constraints, generating potentially painful complications, and on the other hand, the improvement of sleep provided by continuous positive airway pressure (PPC) ventilation could "normalize" the pain perception thresholds. It was shown an early rebound effect after treatment on increasing pain threshold in the healthy subject. We want to check it among obese patients with OSA in early and mid-term.
This investigation is designed to evaluate the comfort, ease of use and performance of a trial nasal mask for the treatment of Obstructive Sleep Apnea (OSA) in the home environment.
Airway management is a core clinical skill in anaesthesia. Pre-oxygenation prior to induction of anaesthesia is standard practice to prevent desaturation. Apnoeic oxygenation in adults is effective and prolongs the time to desaturation. The effectiveness of apnoeic oxygenation in the adult is well document, however evidence in the paediatric is lacking. Therefore, the aim of this study was to investigate the effectiveness of apnoeic oxygenation during airway management in children. This was a pilot randomised controlled trial. Patients were randomised to either receive apnoeic oxygenation or standard care during the induction of anaesthesia. The primary outcome was the duration of safe apnoea, defined as a composite of the time to first event, either time for SpO2 to drop to 92% or time to successfully secure the airway, and the lowest SpO2 observed during airway management. Secondary outcomes were number of patients whose SpO2 dropped below 95% and number of patients whose SpO2 dropped below 92%.
The main objective of this study is to compare the effect of the non-surgical periodontal treatment on serum and saliva oxidative stress parameters in patients with periodontitis and obstructive sleep apnea syndrome (OSAS) and in patients with periodontitis only.
Assessment of the association of maxillary expansion using a rapid palatal expansion, use of a mandibular advancement appliance (MGA™) and of a device allowing sleep in a semi-seated position (Yoobreath™) in patients with Obstructive Sleep Apnea (OAS). MGA™ and YooBreath™ constitute the Yookid system™.
Obstructive sleep apnea (OSA) is an extremely common disease with inadequately explored neurocognitive consequences. The investigators will study OSA patients before and after treatment to understand how OSA changes decision making abilities, and whether treatment can reverse such cognitive changes. These results could provide deeper insight into how OSA affects decision making either temporarily or permanently, and provide another rationale or motivation for treatment of OSA in adults.
This study evaluates the utility and reliability of Somnocheck micro Weinmann for obstructive sleep apnea syndrome (OSAS) screening in patients affected by resistant systemic arterial hypertension. Results are compared with a modified portable sleep apnea testing (type III portable monitoring: Somnocheck 2 Weinmann).
A prospective double blind, placebo-controlled, randomized cross-over trial to evaluate the effect of lowering cerebral blood flow on the ventilatory chemoreflexes (acute hypoxic and hypercapnic ventilatory responses).
The aims of this study are to 1) determine the optimal levels of O2 flow which prevent nocturnal O2 desaturation while minimizing periods of hyperoxia during the course of nocturnal oxygen therapy (NOXT) in heart failure patients with reduced ejection fraction (HFrEF) patients with CSA/CSR; 2) document whether within-patient EO2F values change over time during NOXT, and identify factors which predict changes in EO2F; and 3) examine how well a conventional stepwise titration procedure compares to a breath by breath titration using an automated O2 titration system in terms of targeted flow rate and night time oxygenation (oxygen desaturation index, time spent at specific SpO2 targets).
