Filter by:The purpose of this study is to evaluate the safety and efficacy of four times daily Positive Expiratory Pressure (oPEP) (Aerobika ®) maneuvers over three weeks in individuals with bronchiectasis and chronic obstructive pulmonary disease (COPD) with chronic sputum production. The investigators hypothesize that four times daily positive expiratory pressure using the Aerobika ® will significantly improve dyspnea, movement of mucus, St. George's Respiratory Questionnaire (SGRQ) score, and six-minute walk distance (6MWD) after three weeks of four times daily administration.
The purpose of this study is to evaluate the safety and efficacy of four times daily oscillatory Positive Expiratory Pressure (oPEP) (Aerobika ®) use over 4 weeks in individuals with stable chronic obstructive pulmonary disease (COPD). The investigators hypothesize that daily oPEP use will significantly improve St. George's Respiratory Questionnaire (SGRQ) score, six-minute walk distance (6MWD) and forced expiratory volume in one second (FEV1) after four weeks of four times daily administration.
Background：Respiratory muscle weakness is observed in chronic obstructive pulmonary disease(COPD) patients and contributes to hypercapnia, dyspnoea, nocturnal oxygen desaturation and reduced walking distance.During exercise it has been shown that diaphragm work is increased in COPD and COPD patients use a larger proportion of the maximal inspiratory pressure (MIP) than healthy subjects. This pattern of breathing is closely related to the dyspnoea sensation during exercise and might potentially induce respiratory muscle fatigue. Inspiratory muscle training(IMT) increases inspiratory muscle strength and endurance, and decreases dyspnoea.But the mechanism of IMT still lack of research. Purpose：The experiment is aim to compare of the similarities and differences of transdiaphragmatic pressure by detecting the transdiaphragmatic pressure of COPD patients and healthy volunteers in different intensity of threshold load conditions. Thus investigate how inspiratory muscle training works or mechanism in lung rehabilitation programmes of COPD.And emerging the theoretical basis of inspiratory muscle training from respiratory physiological mechanism.
Asthma and Chronic obstructive pulmonary disease (COPD) results in over a million hospitalizations in the United States annually and COPD is the third leading cause of 30-day re-hospitalizations. Clinical trials have established the efficacy of treatments primarily dispensed via respiratory inhaler devices that reduce morbidity and health care utilization if they are used correctly. The effectiveness of these medications in real-world settings is limited by the fact that patients often do not use inhalers correctly. Current guidelines recommend assessing and teaching inhaler technique at all health care encounters, including hospitalization. Over 75% of hospitalized patients in an urban, predominantly underserved population misused their respiratory inhalers, highlighting a missed opportunity to educate these patients with high potential to benefit. Hospitalization, therefore, provides a potential 'teachable moment' to correct this misuse. My preliminary data indicate that one strategy, in-person teach-to-goal (TTG), is effective in teaching hospitalized patients proper inhaler technique and is more effective than simple verbal instruction. While TTG is a promising, several limitations prevent widespread adoption. TTG is time-consuming and costly. Also, reinforcement may be needed, which may be impractical with in-person TTG. One potential method to surmount TTG's limitations is use of interactive video module education (VME) that has the potential to be less costly, maintain fidelity, and be more easily extended into the post-discharge setting than in-person TTG. Before widespread implementation of VME, it is critical to rigorously develop and test VME for inhaler education in the hospital setting. Ultimately, it will also be important to understand patients' ability and willingness to use post-discharge VME for educational reinforcement to allow for this strategy to transition patients across care settings from hospital to home. We hypothesize that interactive VME will lead to non-inferior rates of ability to demonstrate correct inhaler use compared to rates with TTG among hospitalized patients with Asthma or COPD. For this study we are testing the preliminary efficacy of VME to teach respiratory inhaler technique prior to implementing a larger RCT to test the comparative effectiveness of VME versus TTG.
This is a long-term safety trial of 48 weeks. Eligible subjects will enter the 48-week, open-label treatment period to receive one of two treatments (SUN-101 given as 50 mcg twice a day or Spiriva® [tiotropium] given as 18 mcg once a day).
This is a Phase 2a, proof-of-concept, multicenter, randomized, double-blind, double dummy, 3-treatment, parallel study, with low and high YPL 001 doses (low dose and high dose twice daily [BID]) and a placebo control in moderate to severe Chronic Obstructive Pulmonary Disease (COPD) patients.
The objective of this exploratory study is to examine the utility of high resolution computed tomography (HRCT) to measure changes in functional pulmonary imaging parameters as a function of short term a) iNO administration and b) nitric oxide (NO) cylinder concentration using the investigational medical device INOpulse® DS-C in subjects with WHO Group 3 PH associated with COPD on LTOT (Part 1) and in Subjects with WHO Group 3 PH associated with Idiopathic Pulmonary Fibrosis (IPF) on LTOT (Part 2 and Part 3)
A comparison of albuterol treatments using hypertonic saline (3%) versus standard saline (0.9%) in patients with admitted patients COPD in regard to Modified Borg Dyspnea scale scores after 4 treatments within 24 hours.
The aim of this multi-centre, double blind, randomised, controlled trial (DBRCT) is to assess the effect of low dose theophylline, singly and in combination with low dose oral prednisone, on COPD (Chronic Obstructive Pulmonary Disease) exacerbations, quality of life and secondary clinical outcomes compared with usual therapy and placebo over 48 weeks of treatment. 1670 symptomatic patients with COPD will be recruited in China for comparison of low dose theophylline versus placebo and low dose theophylline + low dose prednisone The primary end-point for this study is the annualised COPD exacerbation rate between the treatment groups. Secondary outcomes included time to first severe exacerbation requiring hospitalisation or death, health status, and pre- and post-bronchodilator spirometry.
This study aims to assess usual walking speed (4-metre gait speed) and markers of sarcopenia predict mortality in patients with chronic respiratory disease.
