Comparison of a Demand Oxygen Delivery
Conducting a randomized control trial of oxygen in children with Down syndrome to treat moderate to severe obstructive sleep apnea. The aim of the study is to conduct a comparison between the 2 methods of oxygen delivery during sleep in 15 children from Cincinnati Children's Hospital and Children's Hospital of …
EFFECT OF A SUBSTANCE P ANTAGONIST ON THE SECRETION OF ALDOSTERONE IN PATIENTS WITH OBSTRUCTIVE SLEEP APNEA SYNDROME AND ARTERIAL HYPERTENSION
Obstructive sleep apnea syndrome (OSAS) is associated with hyperaldosteronism with elevated plasma aldosterone/renin ratio, the physiopathological mechanism of which remains uncertain. This hyperaldosteronism contributes to the development of arterial hypertension and cardiovascular complications observed in patients with OSA, in particular by increasing arterial stiffness and heart rate variability. The frequent …
The Role of the Device Operating Under the Continuous Positive Airway Pressure in the Recovery Process of Cochlea
Hypothesis: Patients with obstructive sleep apnea syndrome (OSAS) have cochlear receptor cells damage because of prolonged, recurrent hypoxia. The use of devices operating under the continous positive airway pressure (CPAP) leads to the recovery of cochlear receptor cells. Aims To determinate whether there is cochlear receptor cells damage in OSAS …
Preliminary Evaluation of a RCMP to Predict Failure of Maxillomandibular Advancement Surgery for OSA
Maxillomandibular advancement (MMA) surgery, one of the most successful surgical procedures for the treatment of obstructive sleep apnea (OSA), is predominantly used to manage patients with moderate to severe OSA. However, limiting factors include incomplete response in some cases, unfavorable facial changes as a result of large advancements, and risk …
Increasing the Use of an Anti-snoring Mouth Guard (Mandibular Advancement Appliance) to Prevent Upper Airway Collapse During Sleep in Patients With Obstructive Sleep Apnoea.
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, …
Effects of Lung Volume on Upper Airway Patency During Drug Induced Sleep Endoscopy
Obstructive sleep apnea (OSA) is a disorder where a person has recurrent choking episodes during sleep. Surgery can treat OSA and drug induced sleep endoscopy (DISE) is a procedure that surgeons use to evaluate the throat while a person is sedated, mimicking sleep, to help determine if surgery might be …
New Perspective on Exploring the Post-apneic BP Surge in Patients With OSA
The nocturnal short-term BPV induced by sleep-breathing events is affected by many factors. The purpose of the study is as follows: (1) to explore the relationship between nocturnal short-term BPV and vascular endothelial function and sympathetic activity in patients with OSA respectively, (2) to explore which play the key role …
Effectiveness of an E-health Intervention in Patients With Obstructive Sleep Apnoea
Obstructive sleep apnoea is a highly burdensome condition that not only impairs function but also confers a risk of cardiovascular disease. This is particularly evident among those who are poorly compliant with continuous positive airway pressure ventilation therapy. In the management of a chronic and frequent pathology such as OSA, …
Patient-centered and Neurocognitive Outcomes With Acetazolamide for Sleep Apnea
Obstructive sleep apnea (OSA) is a severe type of snoring causing people to choke in their sleep. It affects millions of Americans, causing many health problems. For example, patients with OSA often feel very sleepy and are at risk of falling asleep while driving. OSA also causes elevated blood pressure, …
Obstructive Sleep Apnea - Autonomic and Vascular Exploration
The goal of this clinical trial is to assess the effect of CPAP withdrawal on vascular and autonomic function in patients with obstructive sleep apnea. The main question it aims to answer is: • Is the pulse wave amplitude index able to predict the impact of sleep apnea treatment withdrawal …
