Filter by:Recent studies have reported that some Chronic Obstructive Pulmonary Disease (COPD) patients may have a suboptimal ability to generate a sufficient inspiratory effort to achieve adequate lung delivery of inhaled medications through dry powder inhalers. Sparse data is available about the inspiratory capacity of these patients in the home setting, whether clinically stable or when experiencing worsened respiratory symptoms outside the acute care setting. This study is undertaken to better understand the proportion of patients with suboptimal peak inspiratory flow rate (sPIFR) measurements amongst COPD patients receiving dry powder inhaler(s) (DPI) in the ambulatory setting. Further, the study will characterize PIFR over time, the variability of PIFR measurements, and the associations with potential predictors (demographics, clinical, Patient-Reported Outcomes (PRO), body position, and device) as well as exacerbations frequency and change in PIFR around period of exacerbation.
Assessing the impact of anesthesia practice on global warming and carbon footprint becomes part of the standard of care and is growing concern within the anesthesia community. Global Warming Potential (GWP) is a measure of how much a given mass of greenhouse gas contributes to global warming over a specified time period. Inhaled anesthetics have various GWP20: 349 for sevoflurane and 3714 for desflurane. However, GWP20 and CDE20 alone are not sufficient to evaluate the environmental impact of anesthetic gases. Other parameters must be included in the analysis: fresh gas flow (FGF), carrier gas (air, O2, N2O) and potency of the anesthetic gas. Unfortunately, the majority of trials did not fully consider the FGF reduction and the fact that desflurane can be administered with new closed or very low-flow anesthesia circuits as opposed as the recommended 2L/min that must be used for sevoflurane according to its monography in Canada. Most of the calculations were made on a purely theoretical approach that could be different from actual measurements based on a strictly monitored anesthesia practice. When continuous and accurate gas monitoring and analysis is used as recommended nowadays, the use of closed or semi-closed-circuit anesthesia with very low FGF might allow for a reduction of more than 80% of the anesthetic gas administration and its consequent pollution. By properly monitoring the anesthesia depth and analgesia adequacy, the investigators can reduce the gas consumption. The proposed study will aim at determining whether with the help of high-quality monitoring (BIS and NOL) and high-end ventilators that allow minimal fresh gas flow, the use of desflurane remains more polluting than sevoflurane.
This study aims to determine the possible effects of inspiratory muscle training on cardiovascular, respiratory, physical and psychosocial functions in patients with PH.
Two important mechanisms play a major role in the pathogenesis of type 2 diabetes: insulin resistance of the target tissues and the impaired insulin secretion from pancreatic β-cells. Postprandial factors (such as insulin) are perceived by the human brain and induce signals that regulate glucose metabolism via the parasympathetic nervous system. Deep breathing exercise can increase parasympathetic nerve activity. Heart rate variability (HRV) in healthy people can be significantly increased by deep breathing maneuvers, indicating a shift from sympathetic activity to parasympathetic activity. The hypothesis is that this postprandial shift results in a change in peripheral glucose metabolism. In turn, the increased parasympathetic activity could potentially result in a change in postprandial insulin sensitivity or secretion. To test this hypothesis, this study investigates the effect of deep breathing exercise versus normal breathing on insulin sensitivity, on insulin secretion, glucose tolerance, resting energy expenditure, and on parasympathetic tone (analysis of heart rate variability).
The study will characterise inspiratory flow parameters across placebo dry powder inhaler Easyhaler (2 inhaler versions) and placebo Spiriva inhalation powder capsule inhaled via HandiHaler in patients with chronic obstructive pulmonary disease (COPD) and in healthy volunteers. Substudy: Easyhaler® and HandiHaler® Usability study in patients with COPD; to assess patients acceptability, preference, correct use and ability to learn to use Easyhaler and HandiHaler (with capsules) and to compare PIF rate via In-Check Dial meter with the PIF rate via spirometer in the main study.
A randomized control trial was conducted at physiotherapy department of Pakistan Railway General Hospital from July 2017 to Dec 2017. 30 patients with stable COPD were enrolled in the study on the basis of inclusion and exclusion criteria. The participants were randomly assigned into two groups, Group A= interventional group, Group B = control group through toss and coin method using non-probability convenient sampling technique and written consent was obtained from each patient participated in the study. From 30 patients 15 patients were randomly allocated to each group, Group A: Interventional (n= 15), Group B: Control (n=15). 1 patient in control group B was dropout because he didn't come for follow up. Overall 29 patients were evaluated for study as in Group A, interventional (n=15) and Group B control (n=14).Patients in group A were performed breathing control at the start of session and then Purse lips breathing technique during aerobic bicycling for 8 min while in group B patients first perform breathing control and then aerobic bicycling for 8 min. Subjects in both experimental and control group underwent spirometry and baseline vitals, such as Respiratory rate, blood pressure, and oxygen saturation, at rest and at the completion of session was noted. Borg scale of dyspnea also used to rate the level of dyspnea at rest and at the end of session. Clinical COPD Questionnaire (CCQ) was used at 1st and final week of evaluation. It was 6 weeks training protocol, with three days per week session was given to the patient.
Complex patterns of patient-ventilator interactions could be miscalculated by visual observation of mechanical ventilator screens or current algorithms based on physiologic waveforms to detect patient-ventilator asynchronies. Therefore, we aim to characterize, validate and study the clinical distribution and implications of an automated and personalized non-invasive tool based on Entropy to detect Complex Patient-Ventilator Interactions (CP-VI) during mechanical ventilation, defined as breathing pattern change and/or clusters of asynchronies, over the signals of airway pressure (Paw) and airway flow (Flow).
Inhalation burn injury and lung complications caused by large surface burns occurring during a fire remains a serious problem. Pulmonary rehabilitation has been used successfully to improve pulmonary function(PF) in patients with chronic obstructive pulmonary disease. But there were no studies that pulmonary rehabilitation induce improvements in PF in patient with large surface burn and inhalation injury. The investigators will performe pulmonary function and respiratory muscles strength evaluation in 40 patients with thermal injury in order to evaluate the effects of pulmonary rehabilitation in patients with thermally injury.
To determine if Home-based Environmental Interventions (HEI) that improve home air-quality problems can improve asthma outcomes. Participants will benefit through home-based environmental interventions that improve home air-quality problems and improve asthma outcomes. All participants will receive a Breath Easy at Home Kit, which could help with reducing environmental exposures. The primary objective is to assess the feasibility and acceptability of the HEI measured by the proportion of families completing intervention components and proportion of caregivers expressing satisfaction with intervention components. Secondary objective is to explore the efficacy of a HEI on reducing environmental exposures measured using personal wristband monitors. Exploratory objective is improvements in asthma control following HEI measured using asthma control scores and lung function. The fourth objection is to explore correlations between demographics, body weight, housing characteristics (smokers, electronic cigarette use, number of pets, housing type) with measures of acceptability, satisfaction and improved exposure markers.
Most of the asthma patients prefer complementary and integrative applications as they continue to experience asthma symptoms despite pharmacological treatment. Pranayama, one of these treatments, is a breathing-based technique and is a part of yoga, an ancient Indian science. This study was carried out as randomized controlled single blind study in order to analyze the effect of pranayama breathing technique applied to individuals suffering from asthma on asthma control, pulmonary functions and quality of life. The study comprised 50 patients in total, as 25 patients in pranayama group and 25 patients in control group. The approval of ethics committee, permissions from the institutions, and informed voluntary approval of the individuals were obtained to conduct the research. The data of the research were collected through the application of Asthma Control Test (ACT), Asthma Quality of Life Questionnaire (AQLQ), pulmonary function test (PFT), and patient observation chart. Pranayama breathing technique was applied to pranayama group 20 minutes once a day for four weeks, and relaxation technique was applied to relaxation group similarly in addition to standard treatment. ACT, AQLQ, and PFT were evaluated twice as before and after the one month of application process. Meanwhile, the patients' PEF measurements were followed with individual PEF meter on daily basis. The value of p<0.05 was accepted statistically significant in the data analyses.
