Filter by:This will be a prospective study in subjects with Obstructive Sleep Apnea (OSA) to characterize the clinical performance during a single night of therapy with a FRESCA mask compared with a single night of therapy with their existing nasal Continuous Positive Airway Pressure (CPAP) mask.
Obstructive sleep apnea (OSA) is a risk factor for complications during pregnancy and current screening tools for OSA have not been shown to be reliable in pregnant women. The primary aim of this study is to develop a valid screening tool to identify at-risk pregnant women, so that they can be further evaluated and treated. Women with OSA may also be at risk for respiratory complications related to opiate administration for post-cesarean delivery pain. A secondary aim of this study is to evaluate post-operative minute ventilation in women who undergo cesarean delivery using a novel method of non-invasive minute ventilation monitoring.
This is a prospective observational study evaluating all patients requiring mechanical ventilation. Data will be gathered regarding the events prior to ventilation and the indication for mechanical ventilation. In-hospital and post-admission outcome will be monitored.
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.
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.
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.
The purpose of this study is evaluating the effectiveness of three-stair-position (TSP) on the rate of Apnea of Prematurity (AOP), the feeding performance and the vital signs.
The purpose of this randomised controlled study is to determine the impact of continuous positive airway pressure (CPAP) versus sub-therapeutic CPAP (placebo) on the control of gait upon severe sleep apnea patients, based on stride time variability.
