Active clinical trials for "Dyspnea"

The goal of this clinical research study is to learn if specialized breathing devices reduce the sensation of shortness of breath in patients with advanced cancer who are experiencing shortness of breath. Researchers want to learn if these devices can help to control shortness of breath. The 2 devices being tested and compared are called BiPAP (bilevel positive airway pressure) and Vapotherm.

Dyspnea (shortness of breath) is a complex experience that includes interpretation of physical impairments and associated distress to the person. The role of mind-body interactions in the experience of the symptom of dyspnea suggests that complementary and alternative medicine (CAM) therapies may be effective in abating dyspnea and improving patients' health-related quality of life. CAM strategies work in a number of ways that are directly applicable to dyspnea, such as decreasing the stress response, inducing relaxation, and facilitating a less distressful interpreted experience of physical disorders. We have combined a number of established CAM approaches aimed at breath-centered mindfulness and relaxation into an single therapy, mind-body breathing therapy (MBBT). The purpose of this study is to test the efficacy of MBBT in improving dyspnea and health-related quality of life for patients with emphysema (chronic obstructive pulmonary disease).

The purpose of this pilot study is to compare the clinical effects, safety profile, and economic impact of standard therapy plus Natrecor® (nesiritide, a recombinant form of the natural human peptide normally secreted by the heart in response to heart failure) to standard therapy plus placebo in patients who present to the Emergency Department with worsening congestive heart failure (CHF) and are treated in the Emergency Department /Observation Unit.

Breathlessness during exertion is a major limiting factor for patients' physical capacity and activity. Increased exertional breathlessness often results in impaired activity, spiraling deconditioning and further worsening of exertional breathlessness, quality of life and prognosis. Recalled symptoms (from memory) can differ substantially from the actually experienced symptoms.The recall of symptom intensity is affected by several factors including the experienced peak intensity and the intensity at the end of the episode. This 'Peak-end-rule' has been reported in studies of pain, and in breathlessness in daily life and during exercise. A randomized trial reported that adding a time period with decreased pain at the end of a colonoscopy decreased the patient's recalled total pain of the event, improved their overall perception of the event and made them more willing to participate in similar procedures in the future. Pulmonary rehabilitation training is the first line treatment for exertional breathlessness and deconditioning in cardiorespiratory disease. However, the training as well as physical activities of daily life are often limited by the person's perception of his/her capacity, which is based on recalled breathlessness during exertion. The person's predicted breathlessness - that is, the level of breathlessness that the person predicts will occur during a future activity, is likely a major determinant of his/her willingness to participate in training as well as of the level of physical activity in daily life. To improve the effectiveness of cardio-pulmonary rehabilitation training and the patients' health status, new approaches for decreasing the perceived exertional breathlessness and optimize training are needed. The investigators hypothesize that adding a period of lower breathlessness intensity at the end of training might be a way to manipulate the recalled (remembered) symptom intensity during the training, and to improve the subject's perceived future exercise capacity and willingness to participate in physical exercise/ training.

To develop an experimental model of dyspnea by external thoraco-abdominal elastic strapping at rest in order to study the mechanisms involved in the relief of dyspnea by the administration of high flow by nasal cannula (HFNC).

This study will evaluate the ability of High Velocity Nasal Insufflation [HVNI] next generation nasal cannula designs to effect ventilation and related physiological responses relative to the conventional legacy cannula design.

Treatment options for unilateral diaphragm paralysis are limited. Diaphragmatic plication via mini thoracotomy is sometimes considered in the University Hospital Leuven if severe symptoms persist for longer than 12 months after initial diagnosis. Preliminary data indicate that daily inspiratory muscle strength and endurance training can lead to increased nondiaphragmatic inspiratory muscle recruitment and help those with symptoms from diaphragmatic paralysis. Randomized controlled trials comparing intervention groups with improvements achieved by natural recovery in the first months after diagnosis are however so far lacking. The objective of the current study is therefore to investigate the effects of daily inspiratory muscle training in the first 6 months following diagnosis of unilateral diaphragmatic paralysis. The investigators hypothesize that respiratory muscle training in symptomatic patients with UDP (in comparison with a control group) will reduce symptoms of exertional dyspnea (primary outcome) and will improve respiratory muscle function (at rest and during exercise) and pulmonary function (sitting and supine).

Due to various comorbidities affecting the respiratory system, older speakers are at risk of experiencing breathing discomfort (dyspnea) during high-demand vocal activities such as singing, loud speaking, and speaking while exercising. Dyspnea during speech can promote avoidance of certain situations involving voice production, thus leading to vocal deconditioning and decreased quality of life. The goal of this pilot study is to test the feasibility and acceptability of a 4-week remote group intervention targeting phonatory dyspnea, and to gather preliminary efficacy data. Participants will receive an intervention including a 2-week socialization phase (control condition) and a 4-week speech breathing intervention phase (experimental condition). Both phases will be delivered remotely and in a group setting (10 participants per group).

The aim of this study is to utilize lung ultrasound to detect the development of extravascular lung water in patients undergoing clinically indicated invasive hemodynamic exercise stress testing for symptomatic shortness of breath. The study will correlate the lung ultrasound findings with cardiac hemodynamics and measurements of extravascular lung water in an effort to better understand the pathophysiology of exertional dyspnea.

The aim of our study is to compare the effectiveness of the supervized pulmonary telerehabilitation program and the cognitive telerehabilitation method, which includes pulmonary telerehabilitation methods, in patients with severe stage COPD who have difficulty exercising heavily. The effects of pulmonary and cognitive rehabilitation on dyspnea, muscle strength, functional capacity, quality of life, anxiety and depression levels in this patient group will be examined. The number of studies in the literature in which the pulmonary rehabilitation program was applied as telerehabilitation is insufficient. Considering that this patient group is not motivated and has difficulty in exercising, motor imagery and movement observation methods from cognitive rehabilitation methods may be alternative methods for these patients. Although these methods have been very popular in recent years in terms of researching and demonstrating their effectiveness in various patient groups in the literature, no study has been found in which the effects of these methods have been applied in pulmonary disease groups. This study aims to contribute to the serious gap in the literature on the application of pulmonary telerehabilitation and its effectiveness, and to be an original study by investigating the effectiveness of motor imagery and action observation, which are popular rehabilitation methods of recent years, in COPD patients in the pulmonary disease group for the first time.
