Filter by:The aim of this study is to compare oxygen desaturation during two tests: the 6 minute walk test and the 3 minute step test, for COPD patients.
The aim of this interventional, randomized, double-blind, monocentric, cross-over study is to quantify the possible deleterious effect on the cardiac autonomic nervous system control of two long-acting anticholinergic bronchodilatators (tiotropium and glycopyrronium) and one beta-2 agonist long-acting bronchodilatator (indacaterol ) in patients with mild COPD.
To assess the infective etiologies by quantitative polymerase chain reaction (qPCR) of acute exacerbation of COPD and asthma who required hospitalization. To identify the HRV subtypes that are associated with COPD and asthmaexacerbations. To assess if the infective aetiologies have associations with the clinical outcome of the patients.
A randomized clinical study to assess the impact of Symbicort® pMDI medication reminders on adherence in COPD patients
Structural changes in skeletal muscles of patients with chronic obstructive pulmonary disease (COPD) have been linked to impaired muscle function, reduced exercise capacity, and increased mortality associated with this disease. Muscle dysfunction also contributes to dyspnea intensity and the ability to sustain exercise, making aerobic exercise training intolerable at the intensity and/or volume required to achieve clinically important changes. Resistance training (RT) is an attractive exercise modality because it is efficacious and more tolerable initially. No work has examined whether a short-term RT program can reduce exertional symptoms and improve exercise tolerance (dyspnea and leg fatigue) in patients with COPD.
In this study the investigators will determine whether the use of High Flow Nasal Cannula Oxygen during test enhances exercise performance in COPD patients on a treadmill.
The aim of this study is to compare exercise capacity in COPD patients through two different systems of supplemental oxygen delivery: High Flow Nasal Cannula Oxygen (HFNCO) and The Venturi Mask (VM).
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.
The study objective is to satisfy the testing requirements for the Qualcomm Tricorder XPRIZE Competition. This requires an oversight model using the Vitaliti CVSM Wearable, Vitaliti Spirotoscope, and Vitaliti IVD Station to continuously monitor the patient's five core vital signs and to detect the health conditions required by the competition.
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.
