Active clinical trials for "Respiratory System Abnormalities"

Bronchoscopy is an examination performed routinely in pulmonology. This exam is considered as uncomfortable by nearly 60% of patients, especially due to respiratory blocking sensation, cough and nausea it causes, despite the use of a local anesthetic. Conversely, this examination is rarely performed under general anesthesia in hospitals in France, because it lengthens the duration of the procedure, increases its cost and can be dangerous for the respiratory failure patient. Hypnosis is an altered state of consciousness between wakefulness and sleep, which can cause the patient to ignore the reality in which he is focusing his attention on his imagination, reducing his anxiety, his painful or unpleasant perceptions and their memorization. The hypnosis benefit has already been evaluated in the control of pain and anxiety in many medical situations, surgical, obstetric and dental. In endoscopy, the results are mixed. In bronchoscopy, hypnosis has, to our knowledge, not been evaluated. In a preliminary study in the endoscopy unit of the Hospital Saint Joseph, involving 66 patients, investigators showed that bronchoscopy was poorly tolerated in more than half of patients and that this poor tolerance was correlated to the level anxiety of patients, but 75% of patients surveyed would prefer the waning redo the examination in the same conditions if their health required it, rather than using a general anesthetic. Investigators then hypothesized that hypnosis would improve tolerance bronchoscopy under local anesthesia, without the need for general anesthesia.

Respiratory physiology involves a complex interplay of elements including control of breathing, respiratory drive, pulmonary mechanics, distribution of ventilation and gas exchange. Body position may also play an important role in respiratory mechanics. While effective methods exist for measuring these variables, they are typically measured in isolation rather than in combination. In pulmonary disease, decreasing mechanical stress and strain and optimizing transpulmonary pressure or the distending pressure across the lung, minimizing overdistention and collapse are central to clinical management. Obesity has a significant impact on pulmonary mechanics and is a risk factor for obstructive sleep apnea (OSA). However, our understanding of these elements is limited even in the general population. The investigators plan to use various validated methods to assess control of breathing, respiratory drive, distribution of ventilation and gas exchange to obtain a better understanding of underlying physiologic signatures in patients with and without obesity and the role of posture/position, with a secondary analysis comparing participants with and without obstructive sleep apnea.

This study intended to examine the effect of manual diaphragm release on pulmonary function, chest wall mobility, and functional ability in female occupational cleaners with respiratory hazards.

The purpose of this study is to determine the efficacy of a remote patient monitoring platform and alert system in reducing adverse events for hospitalized geriatric orthopedic trauma patients.

Following deployment to Operations Enduring and Iraqi Freedom and Operation New Dawn (OEF/OIF/OND), Veterans report breathing problems, difficulty exercising and other symptoms. These symptoms may be related to deployment exposures, such as regional dust and sand, smoke from burning trash, and local industry. Studies have reported poor air quality, but very little is known about the effect that exposure to this polluted air may have on Veterans' short- and long-term health. Investigators will determine whether deployment-related exposures have affected respiratory and nervous system function in these Veterans - data that may then be used to guide rehabilitation. Ultimately, the investigators' long-term goal is to prevent the development of chronic respiratory conditions in this group of OEF/OIF/OND Veterans.

Laparoscopic cholecystectomy is accepted as gold standard in the management of cholelithiasis. Although laparoscopic procedures have many advantages,intra-abdominal CO2 insufflation can cause decreased lung volumes and compliance, increased airway resistance and impaired ventilation-perfusion ratio. In this study, investigators aim to investigate effects of intra-operative PEEP treatment at 3 distinct levels on respiratory dynamics and elimination time of volatile anesthetic agent.
