The NXT_SLEEP study, bringing together industry partners, research groups and (home) care providers, tackles will develop a next generation sleep-monitoring platform that consists of less obtrusive sensors, and that delivers complete and useful information regarding the physiological parameters relevant for sleep-related breathing disorders. These new and innovative sensors need to be validated in a clinical setting where they will be benchmarked with the classical sleep monitoring systems. In order to compare the novel sensors with the classical monitoring system, the investigators use existing technologies that capture simultaneously the acquired signals of different physiological parameters relevant for sleep-related breathing disorders.
Traumatic injury in rural America is a significant cause of morbidity and mortality, and the challenges of a rural trauma system can put patients at unique risk. Prolonged transport times to a trauma center, stopping for care at referring hospitals, and longer exposure to care-associated factors distinguish rural patients from their urban counterparts. Ventilator-associated pneumonia (VAP) is a significant risk in rural patients, increasing hospital stay, healthcare costs, and even mortality in the critically injured. The investigators propose a pilot study to test the hypothesis that a single dose of oral chlorhexidine gluconate (antiseptic) for trauma patients in the prehospital environment will decrease subsequent development of early VAP. Chlorhexidine is currently a standard therapy in intensive care units to prevent airway colonization and subsequent development of VAP. Demonstrating safety and effectiveness of prehospital infection control practices could significantly improve outcomes of traumatic injury in rural America.
The purpose of the study is to compare the pharmacokinetics of nebulized amikacin administered with three vibrating mesh nebulizers coupled with a single limb circuit bilevel ventilator in healthy volunteers. Following our previous in vitro study, our hypotheses are that the pharmacokinetics varies among the devices tested and that a most efficient device can be identified.
The investigators adopt Noninvasive Positive Pressure Ventilation for weaning in tracheotomy patients innovatively. The investigators randomly allocate the subjects into two groups. One group is weaned by traditional strategy. The other one is weaned by Noninvasive Positive Pressure Ventilation by plugging the tracheotomy tube and deflating the cuff.
Project Summary We propose an ancillary study to The Heart and Lung Failure Pediatric Insulin Titration trial (HALF PINT), which is investigating the impact of normalizing blood glucose using insulin infusions on clinical outcomes among children with hyperglycemia and heart and lung failure. In this ancillary study, we will measure plasma levels of inflammatory, coagulation, and fibrinolysis proteins and genotype DNA for polymorphisms among patients enrolled in the HALF PINT trial. The results from this ancillary study will help us to understand potential mechanisms through which normalizing blood glucose provides benefit, which may lead to development of new therapeutic strategies in critically ill children
Background: Patients in the intensive care unit (ICU) are the sickest in hospital, and need advanced life-support. Survivors of critical illness are very vulnerable to weakness and disability. Up to 1 in 4 have severe leg weakness impairing their quality of life for as long as 5 years after ICU discharge. In-bed cycling employs special equipment that attaches to a patient's hospital bed, allowing them gentle leg exercise while in the ICU. The investigators will offer patients in-bed cycling while they are needing a breathing machine, to help them recover from weakness as fast as possible. Before doing a larger trial testing if in-bed cycling reduces disability, data on safety (Is it safe?) and feasibility (Can the investigators do it?) are needed. Objectives: To study the safety and feasibility of in-bed leg cycling in critically ill patients who need breathing machines. Methods: Adult patients admitted to the ICU who need a breathing machine and are expected to survive their ICU stay are eligible. Specially trained physiotherapists will provide patients with 30 minutes of in-bed cycling each day while they are in the ICU. Outcomes: The investigators will study (1) Safety: the heart rate and breathing patterns of patients doing in-bed cycling, while carefully monitoring for safety. (2) Feasibility: whether patients can cycle on most days of their ICU stay, whether patients and their families agree to be a part of the study, and whether the investigators can assess patients' strength in the ICU and at hospital discharge. Relevance: As the Canadian population ages, the demand for breathing machines during acute illness will increase dramatically. Effective methods of physiotherapy are needed for critically ill patients to minimize muscle weakness, speed recovery, and improve quality of life. This pilot study is the first of several future larger studies about in-bed cycling in the ICU. This program of research will help patients needing life support to regain their strength and recover as fast as possible from critical illness.
The purpose of this study was : - to determine the effect of inhaled antibiotics on airway bacteria in ventilated patients - to determine the effect of inhaled antibiotics on respiratory infection
The US EPA Clean Air Multiyear research program is moving toward a multi-pollutant approach to the assessment of air pollution in response to recommendations by the NRC 2004 and the BOSC in 2005. Such an approach better reflects the complexity of real-world air pollution problems and parallels evolving scientific and regulatory considerations. Ozone (O3) and diesel exhaust (DE) generally are major and important components of ambient air pollution. This proposed study will address the agency's goals by investigating the cardiopulmonary health effects in healthy human subjects co-exposed to O3 and DE. The findings derived from these exposures will provide NCEA findings for risk assessments of O3 and DE, as well as the Office of Air and Radiation (includes OTAQ and OAQPS) with information relevant to possible modulation of PM-induced health effects and responses by a gaseous co-pollutant for potential standard setting. Additionally the findings will address the fundamental driving principle of the Clean Air Research strategy related to reduction of health due to air pollutant exposures.
Bronchoscopy with broncho-alveolar lavage is a diagnostic tool in patients with pneumonia. Especially patients with acute or chronic pulmonary diseases are at risk of respiratory failure during or after bronchoscopy. It is known that in these cases bronchoscopy can be performed safely using non-invasive ventilation. It seems probable that high-flow oxygen, which is used in the treatment of patients with hypoxemic respiratory failure, is equally effective in preventing the development of respiratory failure during fiberoptic bronchoscopy while improving patient comfort. In this prospective randomised study the safety of high-flow oxygen is compared with non-invasive ventilation in patients with hypoxemic respiratory failure undergoing fiberoptic bronchoscopy.
