Filter by:The purpose of this study is to determine the safety and efficacy of ONO-5046Na in patients with acute respiratory failure associated with community-acquired pneumonia
This study investigates how different degrees of muscular unloading during mechanical ventilation impact endurance of succeeding spontaneous breathing trials
The study will compare outcomes between individuals with sub-acute, ventilator-dependent tetraplegia using high (20 cc/kg) vs. low (10 cc/kg) tidal volumes during mechanical ventilator support.
The purpose of this study is to evaluate the effectiveness of continuous positive airway pressure ventilation when applied by paramedics to individuals with severe breathing difficulties in the prehospital setting.
In this study the investigators aim to evaluate a new system dedicated to estimate the end expiratory lung volume, by measuring the VO2-VCO2, during mechanical ventilation compared to the helium dilution technique and the computed tomography (CT) scan.
The main objective of the study is to evaluate the predictive factors of the endothelial function to the waning of an acute exacerbation in COPD. It will act to do a multivariate analysis to determine the respective weight of the parameters of the systemic inflammation, of the oxidative stress of the functional respiratory parameters and then functional respiratory parameters. In exacerbated Chronic Obstructive Pulmonary Disease (COPD) patients, there is augmentation of hypoxia and the obstructive ventilatory disorders is more important. This is correlated with an increase in C-reactive Protein (CRP) and of inflammatory cytokines and oxidative stress. It has been demonstrated that there is an endothelial dysfunction in answer to hypoxia. Since the exacerbated COPD patients are hypoxic in most cases , we suppose they have an endothelial dysfunction during exacerbation. So we think we will find an augmentation of vascular resistances ,shown by a peripheral arterial tone too high. And this, certainly, play a part in physiopathology of the COPD exacerbation.
Hypothesis: A protocolized algorithm for sedation in critically ill patients on mechanical ventilation can decrease ventilator days, costs and improve outcome. This is a multicenter observational-interventional study on critically ill patients who require mechanical ventilation for more than 48 hours, involving 13 ICU in Chile. There are two periods (groups): a descriptive phase of sedation practices, and an interventional period in which an analgesia-based, goal-directed, nurse-driven sedation is applied. Main outcome: ventilator-free days between both periods.
To compare a new mode of mechanical ventilation, Automatic Tube Compensation (ATC) with a traditional one, Continuous Positive Airway Pressure(CPAP), on its effectiveness for detecting patients no longer needing mechanical ventilation.
Measurement of Work of breathing (WOB), as well as pressure time product (PTP) of transdiaphragmatic pressures to evaluate the degree of muscle activity and muscle unloading during non-invasive ventilation. The study makes comparison of a new developed auto adjusting controlled mode and a regular spontaneous mode.
An important part of how we decide when a patient is ready to have their breathing tube removed is to have a person breathe without any machine breaths while the breathing tube is still in place. We call this a spontaneous breathing trial. Commonly, while patients have the breathing tube, they are given medications to keep them sedated and comfortable so breathing does not bother them. These medicines are often stopped before the spontaneous breathing trial so they can be more awake for the test. There are signs the doctors look for during the spontaneous breathing trial that suggest the patient might not be ready for the breathing trial to come out. Signs like fast breathing, small breaths, a fast heart rate, or looking more anxious than usual may mean that the patient is not ready to come off the ventilator. However, if someone has been given sedation medicines the entire time they have had a breathing tube and are then woken up, they may naturally get very anxious. They may show the same signs as someone who is failing their breathing test, but in their case these signs are only because they are anxious.Doctors may mistake these signs as failing the breathing test and may not pull the breathing tube out even though the patient is really ready for it to come out. We wish to try and find out if patients do better during their spontaneous breathing trials if they are continued on some sedative medicines to treat anxiety or if they do better if the medicines are stopped before the test.
