Filter by:Establishing breathing after birth is vital for survival and long-term health of premature babies. 10% of all preterm babies fail to breathe after birth and require help with breathing. When infants need help with breathing the clinical team will place a small mask on the babies face to give some breaths to help the baby breath (what the investigators call mask ventilation). This procedure is done million times a day around the world and several times a day here at the Royal Alexandra Hospital. Providing these breaths via mask ventilation is the most difficult step in helping a baby breath at birth. If this is provided wrongly then baby does not receive enough oxygen, which could damage the brain and even cause death. To keep the skill level of every staff member up-to-date every staff member is required to re-train this rescue breaths via mask ventilation once every two years. The investigators believe this is not enough and that daily trainings are necessary to keep your skills up-to-date. The investigators aim to compare to different teaching techniques using daily trainings to see if either improves the skills of the resuscitator providing mask ventilation The study will last 7 month (baseline observations (2 months), intervention period (3 months), After trial period (2 months) The investigators will use our routinely used equipment to record neonatal resuscitation and the investigators also routinely make video recordings to evaluate performance during resuscitation.
Acetazolamide improves central sleep apnea related to opium consumption.
The purpose of this study is to assess the safety and effectiveness of TranQuillTM Sling (a suture or thread used in surgery that is knotless) in snoreplasty (surgery procedure) for the treatment of snoring and mild OSA in adult subjects. The TranQuill Sling Snoreplasty (QSS) is a procedure where the suture will be inserted into the soft palate tissues for the treatment of snoring and/or mild obstructive sleep apnea. Soft palate tissues are tissues in the back of the roof of the mouth. The research results will be used to provide data on feasibility (strengths and weaknesses), safety, performance, and effectiveness data for the Surgical Specialties, Inc as a therapy for snoring and/or mild obstructive sleep apnea. The TranQuillTM Sling is approved by the U.S. Food and Drug Administration (FDA). The TranQuillTM Sling is used in all types of surgery that involved deep tissues in the body. The investigator in charge of the study is Dr. Boyd Gillespie. MUSC and Dr. Gillespie receive financial support from Surgical Specialties, Inc. to conduct the study. MUSC is the only place that this study will be conducted. For this research study the investigators plan to enroll a total of up to 20 subjects at the Medical University of South Carolina.
The primary objective of this study is to determine whether baseline DOC screening can add to clinical and demographic data to predict the occurrence of a composite negative outcome (any of: recurrent stroke, myocardial infarction, death, or admission to a long-term care (LTC) / complex continuing care (CCC) facility) within one year of screening, in stroke prevention clinic patients.
Sleep apnea is a common disease in the general population and more particularly in elderly subjects in whom prevalence can reach 30 % after 70 years old. In adults (<55 years old) cardiovascular consequences are well known and make sleep apnea treatment necessary. However elderly (>70 years old) apneic subjects are less symptomatic in terms of sleepiness, they usually present a lower index of respiratory events and cardiovascular consequences in this population are still discussed, driving some authors to consider sleep apnea in the elderly as a specific disease and making the need for a treatment questionable. In this study the investigators will focus on the comparison between adult and elderly apneic subjects in terms of cognitive and cardiovascular consequences. Adult apneic patients suffer from a decrease of cognitive performance as well as grey matter local atrophy, particularly in the hippocampus and in the frontal lobes. According to fewer studies, white matter can also be affected by a demyelinisation process. These structural modifications are sometimes associated with disorders of executive and memory functions. In the elderly, no clear association can be drawn between cognitive decline and sleep apnea. Moreover, to our knowledge, the cerebral state of elderly symptomatic apneic subjects has mostly not be investigated.
The high prevalence (9% in men and 4% in women) of sleep apnea / hypopnea syndrome (SAHS) in adults is now well documented as well as its cardiovascular repercussions. Previous studies showed a conclusive link between SAHS and severe cardiovascular diseases such as hypertension, myocardial infarction, heart failure and stroke.Then, SAHS is a public health issue in adults. In this context, early detection of such a disease is crucial if the management is tailored to the patient, the practitioner's choice of therapy moving towards continuous positive airway pressure (CPAP) or mandibular advancement device. The detection is based on full nocturnal polysomnography or polygraphic recordings. Polysomnography remains the gold standard but it is a time consuming and costly examination. Polygraphic recording is a test that allows simplified the diagnosis of severe patients, but may not be sufficient for mild form of SAHS. Thus, the SAHS is a pathology under-diagnosed and under-treated. The validation of a technique for identifying patients most at risk to either limit the number of polysomnographic examination is requested.
The purpose of this study is to determine the predictive factors of poor compliance to sleep disordered breathing therapy in chronic heart failure patients treated for central sleep apnea. To characterize nocturia pathophysiology associated with SDB in this population. To use telemonitoring data to define predictive factors of poor compliance.
Fluid retention in the legs due to chronic heart failure (CHF) during the daytime may redistribute to neck when with supine positioning at night. A portion of the shifted fluid accumulates in the neck, and narrows the upper airway, predisposing the patient to obstructive sleep apnea (OSA) and central sleep apnea (CSA). However, the mechanism of overnight fluid shift on OSA and CSA remains unclear. The investigators pre-experiment demonstrated there may be a different mechanism of overnight fluid shift on OSA and CSA. The accumulation of water content in neck soft tissue increases neck circumference and leads to pharyngeal resistance, upper airway collapse and causes OSA. The effect of nocturnal fluid shift on CSA may be because of increasing of chemosensitivity (fluctuation of PaCO2), circulation delay and hemodynamic disordered. This study is aimed to explore the different mechanism of overnight fluid shift on OSA and CSA by comparing the changes of upper airway (inside diameter, water content, and pharyngeal resistance), PaCO2, circulation delay (lung-to-finger circulation time) and hemodynamic (loop gain).
The United States is currently experiencing an increase in the incidence and prevalence of obstructive sleep apnea (OSA). With prevalence in middle-aged adults of 2 to 4% of the population, untreated OSA has been implicated in increased risk for cardiovascular disease, including hypertension and heart failure, daytime sleepiness, and increased risk of motor vehicle accidents. This study was design in order to evaluate the CelonProSleep plus for multi-level radiofrequency ablation (RFA) of the palate and base of tongue as a treatment for mild to moderate obstructive sleep apnea syndrome (OSAS).
To evaluate the efficacy (non-inferiority) in terms of response between patients using custom fitted mandibular advancement devices ONIRIS® and patient using laboratory custom made devices TALI, after 2 months of use. Sleeping tests were performed.
