CPAP in AF Patients With OSA

Atrial FibrillationSleep Apnea

Obstructive sleep apnea is associated with atrial fibrillation. This study is to evaluate the effect of continuous positive airway pressure on the burden of atrial fibrillation in the patients with obstructive sleep apnea and paroxysmal atrial fibrillation.

Obstructive Sleep Apnea

Obstructive Sleep Apnoea (OSA) is a sleep-related breathing disorder that is characterized by the repeated collapse of the upper airway during sleep, resulting in sleep deprivation. Mandibular Advancement Appliances (MAA) or Oral Appliances (OA) is prescribed for the patients with OSA and they have been shown to be effective. However, they rely entirely on the patient's acceptance and use. The aim of this study is to assess whether interventions- additional support approaches, will help patients use their MAA more as compared to those who receive routine care. The investigators also will try and identify factors that help us to understand why some patients choose to wear the MAA more than others. Adults (≥40 years) with a confirmed diagnosis of OSA (apnoea-hypopnoea index >5) and referred for MAA therapy will be included in this study. It is a multicentre study comprised of recruiting patients from secondary care. Patients will be provided with information in relation to the study and written informed consent obtained at their subsequent appointment for placement of MAA. Patients will be randomly assigned to Intervention Care (IC) and Standardised care (SC). Patients will also be provided with a sleep diary to subjectively record their hours of sleep and usage of MAA and an objective adherence record from the micro-sensor included in their MAA design. Data indicating adherence will be collected and evaluated, both subjectively at 3- (T2) and 6-months (T3) and objectively by downloading the data stored within a micro-sensor placed in the MAA device. At the end of the follow-up, the investigators also plan to undertake a qualitative one-to-one interview with patients compliant (users) and non-compliant (non-users) to identify their views of what helps and/or prevents their adherence.

Normotensive OSA Patients With Dipper Circadian Blood Pressure Pattern

NormotensiveSleep Apnea1 more

The principal objective is to evaluate the effect of CPAP treatment on blood pressure (BP) in normotensive patients with dipper circadian pattern with sleep apnea-hypopnea syndrome (SAHS). The secondary objectives are: i) To evaluate the prevalence of the different circadian patterns of BP in ambulatory blood pressure monitoring (ABPM) ii) To establish the relationship between CPAP compliance and BP response; iii) Identify which ABPM variables and biomarkers are related to BP response; iv) Evaluate changes in the biomarkers' profile with the CPAP treatment. Methodology: Open-label, parallel, prospective, randomized and controlled trial including normotensive patients diagnosed with severe SAHS without significant somnolence. 64 patients with dipper circadian pattern will be included and will be randomized to receive CPAP (32) or conservative treatment (32). ABPM and blood sample collection will be performed at the beginning of the study and at 3 months.

Effects of Continuous Positive Airway Pressure Therapy Withdrawal in Patients With Obstructive Sleep...

Obstructive Sleep Apnea

Study design (e.g., double-blind: A randomized, open-labeled, controlled, parallel-group study. Sixty patients will be recruited with moderate to severe Obstructive Sleep Apnea (OSA), previously adherent to CPAP therapy and have controlled OSA defined as Apnea Hypopnea Index (AHI) of < 5 while on treatment. Patients will be divided into two groups after completion of Therapeutic CPAP, Who will continue on same CPAP therapy for 4 weeks they will be randomized into two groups: NO CPAP (NOCPAP Group): Who will stop using the CPAP device. Intermittent CPAP (Int-CPAP Group): Who will use the CPAP device every other night. This trial will also evaluate the effects of CPAP withdrawal (complete or partial) on excessive day time sleepiness (EDS), apnea hypopnea index (AHI), Heart Rate and Blood Pressure.

The purpose of this study is to to compare oxygenation and ventilation on spontaneously ventilating obese patients or those with diagnosed or undiagnosed Obstructive sleep apnea (OSA) undergoing day colonoscopy under Propofol based sedation, between the SuperNO2VA Et™ nasal positive airway pressure (PAP) device and routine care with face mask for oxygen (O2).

Acetazolamide on REM OSA

Obstructive Sleep Apnea

OSA is a highly prevalent disorder that has major consequences for cardiovascular health, neurocognitive function, risk of traffic accidents, daytime sleepiness and quality of life. In particular, REM sleep is accompanied by more frequent and longer obstructive events, that yield more profound hypoxemia than during non-REM (nREM). Exaggerated OSA severity in REM is the consequence of ventilatory drive dips, particularly during phasic eye movements. Unfortunately, the leading treatment for REM and nREM OSA, CPAP-which acts to pneumatically splint the pharynx open-is intolerable for many patients. Treatment outcomes for REM OSA are burdened by further incomplete CPAP adherence later in the night, which commonly leaves REM periods undertreated. In this protocol, the investigators will test the effect of Acetazolamide on REM OSA and on ventilatory parameters such as genioglossus muscle activity and ventilatory drive.
