Filter by:The present pilot randomized controlled clinical trial will test the hypothesis that in patients with ARDS, fixing ventilator settings to the conventional protective ventilatory strategy (VT 6 ml/kg ideal body weight and Pplat ≤ 30 cmH2O, PEEP according the PEEP/FiO2 table), control modes of mechanical ventilation will be associated to a concentration of pulmonary and systemic inflammatory mediators lower than the concentration of inflammatory mediators observed during assisted modes of mechanical ventilation.
The goal of this study is to evaluate the utilization of conventional 'thermally' polarized perfluorinated gases mixed with oxygen as an exogenous inert contrast agent to image the airway spaces in subjects with suspected lung disease, post deployment in Iraq and Afghanistan. This is an open label proof of concept study expanding on work here at Duke.
The purpose of this study is to determine, in preterm infants less than 37 weeks gestation with respiratory distress who are ventilated in the first 48 hours after birth, if mid frequency ventilation strategy using ventilator rate of ≥ 60 to ≤ 150 per minute compared with standard frequency ventilation strategy using ventilator rates of ≥ 20 to < 60 per minute will increase the number of alive ventilator-free days after randomization and reduce the risk of ventilator induced lung injury.
The purpose of this study is to assess whether circulating Angiotensin (Ang) II and Ang (1-7) levels are associated with right ventricular (RV) dysfunction in mechanically ventilated subjects. It is also designed to further characterize the subject population for severity of RV dysfunction. This study will investigate the association of renin-angiotensin system (RAS) peptides and markers of RV function, as measured by echocardiography, in subjects requiring acute mechanical ventilation. Maximum 150 subjects will be enrolled for the study and they will be evaluated over three days period using standard of care investigations, including trans-thoracic echocardiography (TTE) and/or trans-esophageal echocardiography (TOE) echocardiography. The maximum total duration of this study for subjects is 28 days.
The goal of this interventional crossover study, in intubated and mechanically ventilated Acute Respiratory Distress Syndrome (ARDS) patients, is to compare two positive end-expiratory pressure (PEEP) titration techniques regarding: respiratory mechanics, gas exchange, changes in aeration, ventilation/perfusion matching its impact on cardiac function, especially the right heart (RH). The PEEP titration techniques are: PEEP selection based on low PEEP/high FiO2 table ("PEEPARDSnet") and lung recruitment maneuver (LRM) plus PEEPdec titration based on the best compliance of the respiratory system("PEEPLRM").
Randomized controlled trial, comparing two groups of 40 patients each scheduled for open major abdominal surgery. The intervention group was ventilated with a protective strategy consisting on a low Tidal volume (Vt) (6ml/kg of predicted body weight (PBW)), positive end expiratory pressure (PEEP) = 10 cm H2O and recruitment manoeuvres (RM) after disconnection from the ventilator, the control group had classic ventilation (Vt = 8 ml/kg of PBW, PEEP = 4 cmH2O and no RM).
This study evaluates the effect of airway pressure release ventilation (APRV) on lung homogeneity and recruitment in patients with moderate to severe acute respiratory distress syndrome (ARDS). It will do this by comparing the homogeneity of ventilation and recruitment prior to a patient being ventilated on APRV, and at 30, 60 and 120 minutes after starting APRV.
Lung protective ventilation (LPV) has been proposed to reduce the incidence of postoperative pulmonary complications (PPCs), and protect against ventilator induced lung injury (VILI).
This study is designed to assess the feasibility of the measurement of local pleural strain at 4 different anatomical sites. The secondary objectives of the study are: - To assess intra- and inter-observer variability in the measurement of local pleural strain - To identify the strain parameters demonstrating the most clinically relevant and the most significant correlation with a change in tidal volume Hypothesis: The analysis of lung ultrasonographic sequences using speckle-tracking allows the determination of local pleural strain in 4 predetermined pulmonary areas.
The results of this study will help to define the capability and reliability of PulmoVista 500 to detect changes in both global and regional ventilation.
