Active clinical trials for "Dyspnea"

The objective of this study is to evaluate Lung Doppler signals (LDS) among patients presenting to the emergency department with acute dyspnea, in order to determine the diagnostic value of this non-invasive method to discriminate ADHF causing dyspnea from any other cause i.e., non-ADHF causes of dyspnea.

Biofeedback is a therapeutic paradigm that teaches patients how to gain awareness and control over previously unrecognized sympathetic changes such as body temperature, blood pressure, and heart rate. We propose to use a six session biofeedback protocol that includes heart-rate variability (HRV) biofeedback, respiration/relaxation training, and body temperature control to treat patients with unaddressed respiratory symptoms (e.g. shortness of breath) who are under the care of pulmonologists and have not responded to traditional biomedical approaches (e.g. inhalers, pulmonary rehab, etc.).

Dyspnea is among the most common symptoms in patients with respiratory diseases such as Asthma, chronic obstructive pulmonary disease (COPD), Fibrosis, and Pulmonary Hypertension. However, the pathophysiology and underlying mechanisms of dyspnea in patients with respiratory diseases are still poorly understood. Diaphragm dysfunction might be highly prevalent in patients with dyspnea and respiratory diseases. The association of diaphragm function and potential prognostic significance in patients with respiratory diseases has not yet been investigated.

This study will last for approximately 8 weeks and will involve 4 visits. The study is being carried out to validate a shortness of breath questionnaire

The goal of this clinical research study is to compare high-flow oxygen, low-flow oxygen, high-flow air, and low-flow air in helping to decrease shortness of breath in cancer patients. Researchers also want to learn if these therapies can help to improve lung function and quality of life.

In our study, it was aimed to evaluate the effect of inspiratory muscle training on fear of movement due to dyspnea in COPD patients. Participants will be randomly assigned to two groups. Inspiratory muscle training in the training group will be administered at least 5 days a week, 15 minutes twice a day, beginning at 30% of the MIP for 8 weeks. Patients will come to the control once a week, the MIP values will be re-measured and the new training intensity will be determined at 30% of the new value. For the control group, a fixed training session will be given for at least 5 days a week, 15 minutes twice a day, not exceeding 15% of the MIP for 8 weeks.

Dyspnoea is a very common symptom in many diseases, not only cardiorespiratory, but also renal or neurological diseases. It can be defined as " difficult, laboured and uncomfortable breathing […]. It is a subjective symptom. As pain, it involves both the patient's perception of the sensation and his reaction to it ". It can occur during even moderate effort and sometimes also at rest and tends to increase as the disease causing it progresses. Dyspnoea has therefore a significant on the various aspects of the patient's daily life and those around him or her (travel, leisure, daily activities, etc.) leading to a decrease in quality of life and possibly to anxiety and/or depressive symptoms. Among a vulnerable, elderly population that benefits from home care, it affects more than 46 % of patients in north-west of Switzerland. Despite the handicap generated by daily dyspnoea, this complaint is often difficult to recognize by health professionals or family and friends, due in particular to a feeling of helplessness in the care provided. In addition, the treatment of the disease responsible for dyspnoea by the doctor does not always provide relief. In this context, it is essential that people with dyspnoea, families and friends are supported in their experiences and acquire techniques and alternatives that help them better manage dyspnoea on a daily basis. The first objective is to evaluate the feasibility of a dyspnoea support program led by a respiratory care team non-specialized in palliative care and its effect on quality of life and control of dyspnoea symptoms by patients . A second objective is to measure patient's satisfaction about the program.

The world is facing an extremely important global epidemic. Coronavirus disease 2019 (COVID-19) epidemic, which first appeared in Wuhan, China in late 2019 and rapidly affected all countries of the world, was declared as a pandemic by the World Health Organization (WHO) on March 11, 2020. Coronavirus disease 2019 affects both the upper (i.e. sinuses, nose and throat) and lower (i.e. trachea and lungs) airways, causes respiratory tract diseases ranging from asymptomatic or cold to more severe lung diseases (Acute Respiratory Distress Syndrome-ARDS). COVID-19 has many symptoms (i.e. fever, loss of appetite). In cases where the disease has a more severe course, in addition to the symptoms mentioned above, complications such as a severe pneumonia, acute respiratory distress syndrome (ARDS) kidney failure and fatal heart damage may develop. Dyspnea is one of the most prominent symptoms for COVID-19. Since COVID-19 affects the respiratory system, pulmonary rehabilitation has an important place in the treatment of patients. Dyspnea is one of the most prominent symptoms for COVID-19. Our clinical observations are of the opinion that dyspnea is observed even in patients with mild COVID-19 pneumonia. Applying deep breathing exercise with triflo in COVID-19 patients, can contribute to relieving dyspnea, reducing / eliminating anxiety, and increasing quality of life. In the light of this information, the aim of this study is to determine the effect of deep breathing exercise with triflo on dyspnea, anxiety and quality of life in patients with dyspnea who are hospitalized for COVID-19. Research Hypotheses H1: Patients with COVID-19 pneumonia who undergo deep breathing exercise with triflo will have a lower dyspnea level than the patient group in which this exercise is not applied. H2: Patients with COVID-19 pneumonia who underwent deep breathing exercise with triflo will have a lower anxiety level than the patient group in whom this exercise was not applied. H3: Patients with COVID-19 pneumonia who underwent deep breathing exercise with triflo will have a higher quality of life than the patient group in whom this exercise was not applied.

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.

Dyspnea is a frequent, mostly unpleasant and long-lasting, but also often undertreated symptom. Transcranial direct current stimulation (tDCS), a new non invasive method to modify brain activation has shown good efficacy in the treatment of pain especially in the clinical context. Given the fact that dyspnea has many common characteristics with pain, especially concerning the brain areas involved in its central processing, we hypothesize that tDCS may also modify the perception of dyspnea. In order to test this, we first shall determine whether tDCS has a significant effect on acutely induced dyspnea in healthy volunteers. In case of promising results of this pilot study, the next step will be the evaluation of the benefit of tDCS in patients with severe dyspnea.
