Mild intermittent hypoxia (IH) initiates sustained increases in chest wall and upper airway muscle activity in humans. This sustained increase is a form of respiratory plasticity known as long-term facilitation (LTF). Repeated daily exposure to mild IH that leads to the initiation of LTF of upper airway muscle activity could lead to increased stability of the upper airway. In line with PI's laboratory's mandate to develop innovative therapies to treat sleep apnea, this increased stability could ultimately reduce the continuous positive airway pressure (CPAP) required to treat obstructive sleep apnea (OSA) and improve compliance with this gold standard treatment. Improved compliance could ultimately serve to mitigate those comorbidities linked to sleep apnea. Moreover, in addition to improving CPAP compliance numerous studies indicate that mild IH has many direct beneficial effects on cardiovascular, neurocognitive and metabolic function. Thus, mild IH could serve as a multipronged therapeutic approach to treat sleep apnea. In accordance with this postulation, our proposal will determine if repeated daily exposure to mild IH serves as an adjunct therapy coupled with CPAP to mitigate associated co-morbidities via its direct effects on a variety of cardiovascular, metabolic and neurocognitive measures and indirectly by improving CPAP compliance. Modifications in autonomic (i.e. sympathetic nervous system activity) and cardiovascular (i.e. blood pressure) function will be the primary outcome measures coupled to secondary measures of metabolic and neurocognitive outcomes.
This investigation is a prospective, non randomized, non blinded study. This investigation is designed to evaluate the performance, comfort and ease of use with the F&P trial mask amongst Obstructive Sleep Apnea (OSA) patients. Up to 45 OSA patients will be recruited from the Pulmonary Disease Specialists Research database
Nasal polyposis (NP) is a chronic inflammatory disease of the nasal and sinus mucosa leading to protrusion of edematous polyps in the nasal cavity. Prevalence of NP among the chronic rhinosinusitis patients is 25-30 %. NP leads to significant limitations in physical, emotional and social aspects of life of the affected patients. Sleep disorder is frequently reported by those patients with impaired nasal breathing. Till now few studies have objectively assessed the impact of NP on sleep quality. the objectives are to figure out sleep disturbances in NP and to analyze the outcomes of sinus surgery on sleep recovering.
This investigation is designed to evaluate the performance as well as the patients overall acceptance of the interface.
This study is a randomized controlled trial to evaluating the impact of interscalene block on worsening of obstructive sleep apnea in patients undergoing ambulatory shoulder surgery.
In this prospective randomized cross-over trial, 3 different titration procedures will be compared: 1. titration of the mandibular advancement device (MAD) in the home setting based on both the physical limits of the patient's mandibular protrusion and the resolution of subjective complaints, as currently often used in routine clinical practice; 2. an overnight titration PSG using the remotely controlled mandibular positioner (RCMP) with stepwise mandibular protrusion until respiratory events are reduced and 3. incremental protrusion of the mandible during DISE using the RCMP until upper airway collapse at all collapsible levels is eliminated. The aim of this study is to prospectively compare the target protrusion, as well as the treatment outcome in terms of treatment efficacy, of the 3 different titration protocols.
The aim of this study was to estimate and compare the value of the preoperative fentanyl test and the short OSAS screening scale to diagnose severe obstructive sleep apnea；and to observe the required amount of hydromorphone and the adverse respiratory events after adenotonsillectomy.
Obstructive sleep apnea (OSA) is a common condition associated with significant adverse health outcomes. Our overarching hypothesis is that patients with OSA and hypoxia (H-OSA) have greater degrees of insulin resistance in both liver and adipose tissue when compared to those without hypoxia (NH-OSA) thus leading to increased risk for the development of diabetes in the former group.
Sugammadex or neostigmine are given at the end of the surgery to reverse neuro muscular blocking drugs. This study will evaluate whether reversal of NMBD with sugammadex is associated with faster recovery than neostigmine resulting in faster discharge from the operating room (OR) in obese patients with OSA undergoing bariatric surgery. Half of the patients in the study will receive sugammadex and the other half of the patients will receive neostigmine.
The purpose of this study is to determine whether early diagnosis of OSA and initiation of and adherence to CPAP therapy in patients hospitalized for chronic obstructive pulmonary disease reduce 30-day hospital readmission rates.
