Effect of Continuous Positive Airway Pressure (CPAP) Versus Auto-titrating Continuous Positive Airway...
Resistant HypertensionObstructive Sleep ApneaThe primary objective is to evaluate the relative effectiveness of fixed CPAP in comparison to APAP in reducing arterial blood pressure in patients with resistant hypertension and obstructive sleep apnea (OSA). The secondary objectives are: a) to evaluate the relative effectiveness of fixed CPAP versus APAP in improving arterial stiffness, sleep-disordered breathing, sleep quality, inflammatory markers and glucose regulation; b) to identify specific characteristic of persons who respond to the two CPAP modalities in order to identify which device is better for each subject.
Cow's Milk Allergy in Infants With Obstructive Sleep Apnea (OSA)
Obstructive Sleep Apnea SyndromeCow's milk allergy may be involved in the evolution of sleep apnea in infants. The study will assess the effects of specifies diet changes (i.e. non-milk based formula) on the infant. Specifically , infants will be investigated by sleep studies in order to test this hypothesis.
Treatment Resistant Depression and Obstructive Sleep Apnea, Effect of Continuous Positive Airway...
DepressionSleep Apnea1 moreThe purpose of the study is to determine the effect on mood and anxiety symptoms of adding CPAP to the psychiatric treatment of patients with TRD (treatment resistant depression) and associated OSA (obstructive sleep apnea).
Improvement in Baroreflex Sensitivity in OSAS
Obstructive Sleep Apnea SyndromeIndividuals with obstructive sleep apnea syndrome (OSAS) are at high risk for cardiovascular morbidity and mortality. The effect of long-term nocturnal therapy with continuous positive airway pressure (CPAP) on daytime baroreflex sensitivity (BRS), a predictor of cardiac death, was investigated in OSAS patients.
Sleep Apnea: Mechanism and Cerebrovascular Consequences
Sleep ApneaObstructive1 moreThis study will determine the effect of ventilatory stimulation on obstructive sleep apnea in selected patients with stroke. We will select a subset of patients with stroke in the prior 3 months who are most likely to have ventilatory instability as a cause of the upper airway obstruction as indicated by the absence of obesity, an abnormal hypocapnic apnea threshold and resolution of obstructive apnea during CO2 administration. Following baseline polysomnography, patients will be randomly assigned to acetazolamide (250 mg hs [at bedtime]) versus placebo for 7 days. Polysomnography will be repeated and then subjects will cross-over therapies for another 7 days followed by a final nocturnal polysomnography.
Evaluation Of The Pharynx in Patients Undergoing Lateral Pharyngoplasty
Sleep ApneaObstructiveThis study will evaluate the pharynx in patients undergoing lateral pharyngoplasty for treatment of obstructive sleep apnea through MRI, before and 6 months after surgery.
Effect of CPAP on Postoperative Delirium
Sleep ApneaObstructive1 morePatients with a medical condition known as obstructive sleep apnea may be at increased risk of delirium following surgery. This study loans autotitrating CPAP machines to randomly-selected patients who are at high-risk for obstructive sleep apnea with the goal of preventing post-operative delirium.
Revised Algorithm for Next Generation DeVilbiss Healthcare AutoAdjust Continuous Positive Airway...
Obstructive Sleep ApneaThe purpose of this protocol is to improve the current FDA-approved continuous positive pressure auto-titration algorithm, including treatment precision, residual disease detection characteristics and phenotyping with the DeVilbiss brand AutoAdjust CPAP device.
The Impact of Daily Sinus Irrigation on Nasal Symptoms in Continuous Positive Airway Pressure (CPAP)...
Obstructive Sleep ApneaContinuous positive airway pressure (CPAP) is the most commonly used treatment for obstructive sleep apnea. Nasal symptoms such as dryness, itching and congestion are common in CPAP users. Nasal and sinus saline irrigation has been shown to improve these symptoms in individuals with chronic nasal congestion and sinusitis. This is an 8 week study that investigates whether daily saline nasal and sinus irrigation reduces nasal symptoms in patients using CPAP, improves quality of life and CPAP compliance.
Indoor Temperature and Sleep Apnea
Obstructive Sleep ApneaThe purpose of this study is to test whether different indoor temperature affect the frequency of sleep apnea.
