Filter by:The aim of the study is to determine the feasibility of collecting respiratory parameters during recompensation following ADHF (Acute Decompensated Heart Failure)with non-invasive measurements. This could lead to a better understanding of how respiratory parameters may change during re-compensation therapy and could also be a comfortable method for patients.
The aim of this investigation is to determine the incidence of silent interstitial pulmonary edema by chest ultrasound at moderate altitude (3905m). Secondary endpoints are to detect a suspected association with acute mountain sickness (AMS), co-morbidities and endothelial dysfunction (marker of hypoxia responses, endothelial damage and inflammation).
The need for fluid resuscitation (FR) in ICU patients with acute respiratory distress syndrome (ARDS) is common. Indeed, relative or absolute hypovolemia is a common phenomenon that the intensivist must recognize early and treat promptly. Fluid challenge may have adverse side effects associated with fluid administration. The diffusion within the interstitial space may favor edema formation and cause cardiac dysfunction by volume overload. Edema formation is global and may specifically alter pulmonary alveolar epithelial integrity, leading to enhanced alveolar edema and impaired gas exchange. Currently, two types of fluids are frequently used, crystalloids and colloids. Among colloids and compared to crystalloids, albumin has the theoretical advantage of causing greater volume expansion. We hypothesized that a fluid resuscitation therapy with albumin generates less pulmonary edema than a fluid resuscitation therapy with crystalloids. The aim of our study is to compare alveolar fluid clearance, as a marker of alveolar edema fluid resorption, in 2 groups of patients: those treated with albumin and those treated with crystalloid.
To determine if an inhaled hypertonic saline solution has any effect on lung function in patients with acute respiratory distress syndrome (ARDS).
We use a new technology (Nexfin from BMEYE-Inventive Hemodynamics) to monitor Cardiac Output, Blood Pressure, Fluid Responsiveness, Pulse Oximetry, Hemoglobin Concentration, Oxygen Delivery in Climbers during their process of acclimatization on a expedition to Mount Aconcagua.
The objective of our study is to evaluate the efficacy of helmet ventilation as compared with Face mask in patients with respiratory failure.
Mechanisms underlying high-altitude intolerance as well as exercise performance limitation in hypoxia still remain to be fully understood. Recent data suggest that sleep disturbances on one hand and cerebral perturbations on teh other hand may be key mechanisms. The investigators evaluated 12 healthy subjects at sea level and at 4400 m of altitude for 7 days in order to better describe sleep and cerebral responses. The investigators hypothesized that sleep and cerebral disturbances play a critical role for the developement of acute mountain sickness and for exercise performance limitation during acute high-altitude exposure.
The hypothesis of this observational single-center clinical study was to explore the volumetric hemodynamic monitoring in the perioperative period in major and risky thoracic intervention. The investigators monitored the changes in the volumes of blood in the central vessels and heart chambers as well as a volume of fluid in pulmonary tissue (i. e. extravascular lung water).
The aim of this study is to establish a model for the evaluation of drug targets using postural measures to induce changes in lung water concentration as assessed by MRI. A reduction in the magnitude and rate of water transudation with postural changes in patients with congestive heart failure (CHF) could provide a model for the evaluation of various classes of molecules for target validation and for dose selection.
The purpose of this study is to define the current treatment of patients ospitalized with acute cardiogenic pulmonary edema. Clinical and laboratory data collected in the Emergency Department will used to investigate the primary outcome (mortality) and risk factors related to the primary outcome.
