Filter by:Congenital central hypoventilation syndrome (CCHS) is a rare disorder of autonomic and respiratory regulation that alters oxygen delivery to the brain. CCHS patients are at risk for broad neurocognitive deficits. Patients retain ventilatory activity when awake through a respiratory-related cortical network but the need to mobilise cortical resources to breathe lead to breathing-cognition interferences during cognitive tasks. The purpose of this study is to assess the relationship between breathing pattern and attention in CCHS children
Study to assess the prevalence of central sleep apnea in patients with heart failure with reduced or mildly reduced left ventricular ejection fraction (LVEF <50%) followed by case-control study to assess the link between central sleep apnea and cognitive function
An initial small study on 15 children that are already being investigated for central sleep apnoea in the sleep unit at Sheffield Children's Hospital. The central apnoea monitor will be placed around the child's abdomen overnight alongside the sensors already being used for the clinical sleep study and the signals from the two systems will be compared to evaluate the accuracy of the new device.
Patients with chronic pain who use opioids appear to be at increased risk for breathing issues during sleep, termed sleep disordered breathing (SDB). Treatment of SDB often consists of use of a device during sleep that provides continuous positive airway pressure (CPAP) via a mask interface. However, this device is not effective or tolerated in all individuals. The goal of this study is to examine whether a medication called acetazolamide can improve SDB, as an alternative to CPAP treatment. The investigators will measure the improvement in SDB, as well as any change in symptoms, during a 1 week treatment with acetazolamide compared with 1 week of placebo (sugar pill). This study will help to provide data for longer term studies of treatment for SDB in patients who use opioids.
Sleep-disordered breathing (SDB) is prevalent in children and adolescents and untreated SDB impacts key indicators of physical and psychosocial health. Positive airway pressure (PAP) therapy is highly effective for the treatment of SDB and is associated with favorable clinical outcomes but is limited by poor adherence. Emerging literature in adults suggests that intolerance to PAP therapy may be related to coexisting insomnia. However, the presence of insomnia in children with known SDB as well as its impact on PAP adherence have not been explored. This proposal will explore the association of coexisting insomnia on PAP adherence in children with SDB using a cross-sectional study design. The investigators will assess the association between insomnia and PAP therapy adherence, measured as the mean minutes of nightly PAP usage over 6 months of use on objective downloads.
The research study is being done to test heated humidified high-flow air (HHF), as a treatment for OSA.
Sleep at altitude is often poor. The purpose of this study is to evaluate the effects of a single dose of the opioid antagonist, naltrexone, on sleep quality and periodic breathing after rapid ascent to ~3800m altitude.
This study has been developed in order to demonstrate the validity of the DreamKit respiratory effort signal.
In general, central sleep apnea is not as common as obstructive sleep apnea but it is common in patients with heart failure. It has been repeatedly shown that central sleep apnea worsens the prognosis of heart failure. The current concept in the development of CSA is hypocapnia which causes temporary cessation of respiratory neural output. Different methods for supplement of CO2 have been used to eliminate CSA. However, variation of CO2 concentration during overnight treatment and tight-fitting mask made the treatment uncomfortable. It is important to develop a device with a comfortable mask to supply constant low dose CO2 without breathing difficulty. We recently developed a device for treatment of CSA.
This study has been developed in order to demonstrate diagnostic efficacy of the DreamKit device against polysomnography.
