Filter by:The primary objective is to evaluate the performance parameters of the proposed DLAD (Carebot AI CXR) in comparison to individual radiologists.
The purpose of this study is to compare the effects of e-cigarettes and continued smoking on pulmonary and cardiac outcomes in a population with established pulmonary disease.
Background Numerous surgicals treatments have been described for the massive subcutaneous emphysema; however, some of these techniques cannot be carried out in a critical care unit and they are related with high morbidity and exposure in positive SARS COV-2 patients. More effective, less invasive and isolated procedures should be implemented. Technique Negative pressure therapy (NPT) that can allow effective solving of massive subcutaneous emphysema in a short period (5 days) with a minimally invasive approach at the bedside in Covid-19 or non infected critical patients. Conclusion NPT is an effective and low invasive strategy for the management of EES in critical patients with high risk of mortality.
Rationale: The diaphragm is the principal respiratory muscle, which separates the thorax from the abdomen. Hyperinflation of the lung places the diaphragm at a mechanical disadvantage, shortens its operating length and changes the mechanical arrangement of costal and crural components of the diaphragm and consequently decrease the tension that can be developed and the amount of transdiaphragmatic pressure that can be produced. Reducing the lung hyperinflation could improve the diaphragm function mechanically. One of the treatments to reduces lung hyperinflation is the bronchoscopic treatment using endobronchial valves. To our knowledge the change in diaphragm function after bronchoscopic endobronchial valve treatment was never investigated. Objective: To investigate the change in diaphragm function after bronchoscopic lung volume reduction treatment with endobronchial valves (EBV). Study design: Observational study in which the study population will be asked to perform some additional test during regular visits for the bronchoscopic lung volume reduction treatment with valves. Main study parameters: Change in diaphragm function 6 week after EBV treatment measured by ultrasound. The main outcome will be diaphragm motion (difference between maximum in- and expiration).
Patients with severe emphysema have limited options for treatment. Current treatments include lung transplant, lung volume reduction surgery or endobronchial lung volume reduction using valves or coils. These options are only available for a small and selected group of patients. The Free Flow Medical Lung Tensioning Device System (LTD) is thought to be the next generation endobronchial treatment for patients with severe emphysema designed to address this unmet need. The LTD is designed to compress the areas of lung parenchyma most damaged by emphysema and to tension surrounding tissue to help restore lung elastic recoil in a similar manner to the lung volume reduction coils.
Pneumonia is a recurrent element of COVID-19 infection, it is often associated with development of respiratory failure and patients frequently need various degrees of oxygen therapy up to non invasive ventilation (NIV-CPAP) and invasive mechanical ventilation (IMV). Main purpose of this study is to evaluate with non invasive clinical instruments (pletysmography, Diffusion lung capacity for carbon monoxide -DLCO-, six minute walking test and dyspnea scores) and radiological tools (chest X-ray and chest CT scan) the development of medium-to-long term pulmonary sequelae caused by SARS-CoV-2 pneumonia.
The data of patients undergoing bronchoscopic volume reduction procedure will be analyzed retrospectively. Patients will be divided into two groups as patients with and without Pulmonary Rehabilitation before the procedure, and changes in functional levels of patients will be compared.
This is a Post-Market Evaluation of the Zephyr Valve 5.5-LP EBV to assess Treated Lobar Volume Reduction (TLVR), changes in lung function and the safety profile of the Zephyr Valve treatment with the use of at least one Zephyr Valve 5.5-LP EBV.
Chronic Obstructive Pulmonary Disease (COPD) is a frequent disease affecting a growing number of adults in the world which is responsible for a large public health burden through heavy morbidity and mortality. Emphysema is one of a wide spectrum of pulmonary complications linked to COPD, defined as the abnormal permanent enlargement of the airspaces distal to the terminal bronchioles accompanied by destruction of the alveolar wall. Disease progression is correlated to worsening and enlargement of emphysema lesions, sometimes conflating in sizeable bullae, deleterious to normal mechanical pulmonary function. Bullous emphysema (BE) is sometimes eligible to invasive curative treatment through surgery or interventional bronchoscopy. Diagnosis of BE relies on computerized tomodensitometry (CT), the gold-standard for evaluating pulmonary parenchyma. However, CT is not always available, and bullous emphysema can present as pneumothorax on chest radiography. The practice of lung ultrasound is currently growing in respiratory medicine and emergency departments owing to an increasing amount of evidence showcasing its reliability as a diagnostic tool, most notably for pneumothorax and other pleural diseases. Despite BE having been reported to present similarly to pneumothorax in ultrasound, its characteristics have not yet been precisely described. The primary aim of this study is to describe BE using lung ultrasound. Participants with known BE on CT will undergo a simple ultrasound examination. The secondary aim is to compare the characteristics of BE to those of pneumothorax using lung ultrasound. To achieve this, a second group of participants with currently treated pneumothorax will also undergo lung ultrasound.
This pilot study will explore the benefit of Health Coaching on patients with severe symptoms of COPD.
