Filter by:ECMO(Extracorporeal membrane oxygenation) is being essential for cardiopulmonary failure patients. There are two types of ECMO, which is veno-veno (V-V) that can be used in respiratory failure patients and veno-arterial (V-A) that can be used in cardiac failure patients. V-A ECMO can also be used during lung transplantation, substitution of cardiopulmonary bypass, which can show sufficient performance during operation and better postoperative outcome. However, regarding V-A ECMO circulating from femoral vein to femoral artery, there is a pro blem of differential hypoxia which might influence coronary artery and head vessels. In this prospective study, the investigators are planning to put another ECMO catheter into internal jugular vein which takes a role of left to right shunt, to mitigate the hypoxia of coronary artery.
A prospective randomized controlled trial studying the ordering of palliative care consultations in the emergency department (Ig) versus later palliative care consultations in the hospital--ICU or hospital ward(Cg). Patients will be randomly allocated to Ig or Cg with a 1:1 ratio.
This study explores whether patients hospitalized with chronic obstructive pulmonary disease (COPD) exacerbation may have fewer days with prednisolone and with the same treatment effect by controlling the treatment by daily measurements of eosinophils.
Brain oxygenation is determined by the product of CaO2 and the cerebral blood flow (CBF), the modification of one or the other can affect the neuronal O2 availability. Besides the effect of the PaO2, the CBF is also regulated by the PaCO2. During effort in state of hypoxia, the drop of the PaO2 associated to a potential decrease of the PaCO2 and therefore of the CBF, can create an important dizziness between the demand and the supply of cerebral O2. It seems that hypoxia can trouble in a significant way the response of central neurons, just as the production of a motor cortex generated motor command. Studies suggest that exercise in severe hypoxia condition can constitute a necessary threat for brain oxygenation and the motor command, with the consequence a decrease of the exercise performance. This projects aim to study effects of hypoxia on the brain function for patients suffering from chronic respiratory disease. Neurophysiologic responses of the brain while resting or exercising, including drip and cerebral oxygenation, cortical excitation and motor command resulting for hypoxic subjects before and after a treatment to correct abnormalities of gaz in blood. The study will use a multidisciplinary and supplementary methodological approach : the near-infrared spectroscopy (NIRS) to appreciate the drip and cerebral oxygenation, CBF, neurostimulation procedures and electromyography (EMG) to appreciate the cortical excitability, measure the level of central activation and motor command. The goals of this study will be : - Measure the drip and cerebral oxygenation, the cortical excitability, mechanisms of voluntary activation and central fatigue to the effort for the chronic hypoxemic patient compared to healthy control subjects. - Analyse disruptions of locomotion parameters and posturographyc, in simple and double task, involving different levels of cerebral task. - Analyse acute effects of an improvement of arterial oxygenation for patients suffering from chronic obstructive pulmonary disease (COPD) on drip and cerebral oxygenation, cortical excitability, mechanisms of voluntary activation and central fatigue. - Evaluate effects of a treatment by continuous positive airway pressure (CPAP) for patients suffering from obstructive sleep apnea (OSA) with the same parameters.
Study to assess the long-term safety and effectiveness of Spiolto in Japanese patients with Chronic Obstructive Pulmonary Disease (COPD) in real-world setting
The objective of this pivotal study is to evaluate the relative bioavailability of SYN010 HFA Inhaler and Symbicort 160/4.5μg in healthy volunteers with charcoal block.
The purpose of this study is to determine whether exercise can be prolonged in COPD can by the inhaled bronchodilator Stiolto Respimat. The study will identify whether any endurance benefit is due to reduction in fatigue that originates within the skeletal muscles and/or from effects on neural activation of the skeletal muscles.
The purpose of this study is to determine, if it exists, a relation between plateau heart rate from the last 3 minutes of the 6-minute stepper test and heart rate from first ventilatory threshold from cardiopulmonary exercise testing in order to individualise pulmonary rehabilitation in patients with mild to moderate chronicle obstructive pulmonary disease.
This is an observational study examining outcomes and treatment patterns in a community-based cohort of subjects with Chronic obstructive pulmonary disease (COPD) who are based in the Kannapolis, NC area.
This study will evaluate the effects of budesonide (using Symbicort which is budesonide and formoterol) and fluticasone (using Advair which is fluticasone and salmeterol) on the airway microorganisms of patients with moderate-to-severe chronic obstructive pulmonary disease (COPD). This is a randomized, parallel group, two-centered clinical trial study to evaluate the effects of a 12 week treatment with Symbicort 400 mcg BID and Advair 250 mcg BID (via Diskus) on airway microbiota in patients with moderate-to-severe COPD. The control arm of this study will be Oxeze 12 ug BID.
