Filter by:Dyspnea is the most common symptom limiting the ability of COPD patients to perform activities of daily living. Although there has been research involving the benefit of providing Non Invasive Ventilation (NIV) during exercise to increase tolerance overall, there is little research specifically looking at shortening dyspnea recovery times associated with exercise. We hypothesize that providing intermittent non-invasive positive pressure therapy (a form of NIV or PAP) with a handheld device to COPD patients immediately after exertion can relieve their dyspnea, and consequently allow them to be more active. In this study, we are comparing the distance walked as measured by a modified 6-Minute Walk Test (6MWT) of 20 COPD patients using VitaBreath (NIV) device versus Pursed Lip Breathing.
Shortness of breath (dyspnea) is an important symptom during physical exertion in patients with chronic obstructive pulmonary disease (COPD) and is related to respiratory muscle weakness. Dyspnea is a multidimensional sensation. The sensory perceptual domain (perceived dyspnea intensity) has been study extensively. The perception of respiratory distress (unpleasantness of dyspnea) has not received as much attention. Inspiratory muscle training (IMT) has been shown to improve inspiratory muscle function and reduce dyspnea intensity. Balance impairments increasing the risk of falling is another recognized problem in patients with COPD. Postural balance has been shown to be especially impaired in patients with COPD who have pronounced respiratory muscle weakness. Improvements in respiratory muscle function might improve balance control in patients. Respiratory Muscle Metaboreflex is known as respiratory muscle work during exercise reflexively induces sympathetically mediated vasoconstrictor activity, there by compromising blood flow and oxygen delivery to active limb and respiratory muscles. Eight weeks of controlled IMT is hypothesized to reduce both intensity as well as unpleasntness domain of dyspnea perception, improve postural control and improves blood flow and oxygen delivery to limb muscles in patients with COPD who have pronounced respiratory muscle weakness.
This study evaluates the prognostic value of arterial blood gas analysis in a cohort of Emergency Department patients presenting with shortness of breath of any cause, comparing obese and non-obese patients.
In this single centre non-randomised pilot cohort study we wish to quantify the effect of a twice weekly, 8 week, structured responsive exercise training programme on exercise tolerance, symptoms and health related quality of life in patients with Idiopathic Pulmonary Fibrosis (IPF). We also wish to assess the effect of exercise training on fibrotic processes causing IPF through measurement of blood biomarkers of disease activity.
This study aims to assess consequences and causes of hemidiaphragmatic paralysis for ambulatory arthroscopic shoulder surgery in patients with BMI ≥ 30 kg/m².
Chronic Obstructive Pulmonary Disease (COPD) is a common smoking related lung disease. The main symptom in breathlessness. Pulmonary Rehabilitation (PR) - a supervised group exercise and education class - is an effective intervention in COPD to reduce symptoms, improve exercise performance and prevent exacerbations. However some COPD patients are unable to to effectively exercise as they are limited by their breathlessness, despite optimal medical management. By reducing their physical activity to avoid the onset of breathlessness, they become deconditioned and then further attempts at exercise make them more breathless, leading to an inactivity cycle. There is a growing evidence base regarding the use of hand hold fan therapy or air therapy to relieve breathlessness at rest. Limited studies have looked at the use of fan therapy during exercise, and its role on exercise capacity and recovery time, provisional results which indicate it may also be useful during activity. Logically you might expect patients who are less breathless to be able to exercise more, or recover quicker. This study aims to investigate the effects a hand held fan will have on sensation of breathlessness and exercise capacity in patients with COPD. This will involve participants undertaking a standardised field walking test ( 6 minute walk test) with and with out the fan and then comparing the distance covered and how they felt during and after exercise. This will better inform how we structure exercise and advice to these patients in the future to empower patients limited by breathlessness.
Innovations aimed at improving new patient identification, diagnosis, nonpharmacological treatment, supported self-management, and remote monitoring, together with new methods of clinical support could improve outcomes in patients with respiratory disease. The Investigators have developed a model of care incorporating key innovations for patients with asthma, COPD and undifferentiated breathlessness. This service is being implemented within Wessex CCGs. The investigators will assess whether the implementation of the service is effective, and how it can be adjusted, in addition to introducing innovations to assess whether the expected benefits for patients are realised.
