Filter by:The principal aim of this study was to adapt pain neuroscience education to dyspnea, Dyspnea Neuroscience Education (DNE), and measure its effect on dyspnea perception, physica l activity level, disability, quality of life and ventilatory and functional capacity through a randomized controlled trial. The secondary objectives were to evaluate its feasibility and its effect on emotional state (anxiety and depression), medical atten dance, number of exacerbations and the willingness to exercise.
Chronic and progressive dyspnea is the most characteristic symptom of chronic obstructive pulmonary disease. There are studies in the literature showing that electromyography activations of respiratory muscles increase in individuals with chronic obstructive pulmonary disease and that the severity of the perceived shortness of breath is associated with muscle activation. However, no study has been found comparing respiratory muscle activations during pursed lip breathing and normal breathing in the dyspnea reduction positions and supine position used in the treatment and management of chronic obstructive pulmonary disease. The aim of this study is to evaluate the effects of different dyspnea reduction positions on respiratory muscle activations separately, to compare respiratory muscle activation during normal breathing, respiratory control and pursed lip breathing during these different positions, and to classify muscle activations according to the severity of chronic obstructive pulmonary disease.
Purpose of the research; To determine the effects of wearable technology follow-up, breathing exercises with a breathing exercise device and reading aloud on vital signs, fatigue and respiratory function parameters in individuals with COPD. This research will be conducted using a randomized controlled trial model. "Personal Description Form", "COPD and Asthma Fatigue Scale", Visual Analog Scale and pulmonary function tests will be used in data collection.
This study was planned to examine the effect of progressive relaxation exercises applied to lung cancer patients receiving chemotherapy on dyspnea, pain and sleep quality.
Individuals with hypermobile Ehlers-Danlos Syndrome (hEDS) and Hypermobility Spectrum Disorders (HSD) often experience dyspnea. Inspiratory Muscle Training (IMT) has been shown to improve dyspnea and respiratory muscle function; however, the impact of IMT in combination with whole-body exercise training on respiratory muscle strength, dyspnea, and daily function remains unknown. The objectives of this research are i) to evaluate dyspnea, respiratory muscle strength and function, ventilatory parameters, and health-related quality of life (HRQL) in individuals with hEDS and HSD compared to healthy age and sex-matched controls, ii) to explore the contributors to dyspnea during exercise with a specific focus on respiratory muscle structure and function in hEDS and HSD patients and healthy controls, and iii) to assess whether the combination of IMT and whole-body exercise training will be more effective than whole-body exercise training alone in improving participant outcomes in hEDS and HSD participants. It is hypothesized that i) hEDS and HSD participants will have lower respiratory muscle strength, higher peripheral airway resistance, lower HRQL, and higher anxiety and depression levels compared to healthy controls, ii) the contributors to increased exercise induced dyspnea will include decreased respiratory muscle strength, increased airway resistance, and greater prefrontal cortical neural activity, and iii) the combination of IMT and whole-body exercise training will be superior to whole-body training alone for improving dyspnea, respiratory muscle strength and endurance, aerobic capacity, HRQL, anxiety, and depression.
COVID-19, a novel coronavirus, has caused widespread mortality and morbidity since it emerged in 2019. There is ongoing research and growing literature describing severe acute respiratory syndrome (SARS-COV-2). There is a growing population of individuals who have recovered from acute SARS-COV-2 infection. The long-term effects of COVID-19 are unknown. There are growing reports of sequelae after acute SARS-CoV-2 not limited to fatigue, dyspnea, reactive airway disease, organizing pneumonia, pulmonary fibrosis, pulmonary hypertension, pulmonary emboli, and tracheal disease. The incidence and natural history of these findings is unstudied.
Modern management of acute respiratory failure aims to relieve dyspnea and anxiety by providing a non-invasive respiratory support. This approach tries to avoid endotracheal intubation, patient self inflicted lung injuries (PSILI) and diaphragmatic dysfunction. The present study aims to evaluate dyspnea, pulmonary regional ventilation and diaphragmatic function in patients with hypoxemic acute respiratory failure by different observations, and to bring risk factor for intubation out.
Randomized crossover clinical trial in which a group of runners are ask to complete a 15 minutes standardized physical test on a treadmill. The same group of participants are randomized to the order in which they use a facemask (surgical mask, polyester reusable cloth mask) or no mask, while running. Each test, according to the type of mask or no mask, are held on different dates. Heart rate, oxygen saturation and shortness of breath are measured every 3 minutes during the test.
The purpose of the SIDI study is to follow, few months after discharge from the hospital, the patients admitted to the 3 emergency departments in Tunisia for acute dyspnea and to determine the proportion and the factors favoring rehospitalization and death.
Following acute pulmonary embolism (PE), up to a third of patients develop post-PE syndrome described as having persistent breathlessness (dyspnea), impaired exercise capacity, and a reduced quality of life. The post-PE syndrome includes patients with chronic thromboembolic pulmonary hypertension (CTEPH), patients with chronic thromboembolic disease (CTED) those with an obstruction of the pulmonary arteries without pulmonary hypertension, and patients with post-PE related dyspnea without obstruction or pulmonary hypertension. Although therapies exist for the most severe form of the post-PE syndrome (CTEPH) - for most patients there are no available disease specific therapies that reduce symptoms. Despite studies showing increased breathlessness and abnormal exercise responses in patients with CTED, a detailed examination of what causes breathlessness in post-PE syndrome has never been undertaken. It is suspected that reduced blood flow to the lungs contributes to the feelings of breathlessness, particularly during exercise. This study will use inhaled nitric oxide, a medication that increases blood flow to the lungs. Inhaled nitric oxide is used primarily in hospitalized patients in the intensive care unit with respiratory failure, its use in people with post-PE syndrome is experimental. The investigators believe use of this medication may help to relieve symptoms of breathlessness. In order to test this medication, in volunteers with post-PE syndrome, the following will be measured: 1) breathlessness, 2) the signal to breathe sent from the brain to the lungs, 3) the activity of the muscles involved with breathing and 4) the amount of different gasses in the blood during exercise. The investigators will compare breathlessness and exercise tolerance during exercise while receiving: 1) a placebo (normal medical grade air) and 2) inhaled nitric oxide (a medication that improves blood flow to the lungs). By comparing symptoms during these two conditions, it is hoped to obtain a better understanding of what causes breathlessness in people with post-PE syndrome. This clinical research study will recruit approximately 20 clinically stable participants with CTED or post-PE related breathlessness.
