A randomized controlled trial in which icing and airflow stimulation for reduction of dyspnea in patients of obstructive lung disease was done which is characterized as condition of infection described by constant improvement of perpetual constraint of flow of air that is partially reversible and incorporates chronic bronchitis, emphysema and small airway diseases . The tools used were RR, Spirometry, Saturation, Borg Scale, MRC scale, shuttle walk test and St George's Respiratory Questionnaire (St.GRQ) score. Pulse oximeter measured the saturation levels and respiratory rates were alse observed. Borg scale measured rate of perceived exertion ranges from 6(easy physical activity) and 20(worst activity) and MRC measure dyspnea levels. In St.GRQ score between 1 to 8 is symptoms related and 9 to 17 was activity related.Literature review indicate that icing and airflow stimulation reduce dyspnea in patients of obstructive lung diseases.
Chronic Obstructive Pulmonary Disease (COPD) is the fourth-leading cause of death. It is a progressive illness that requires life-long treatment.Promoting airway clearance (AC) using mucolytics together with airway clearance techniques (ACTs) form the basis for pulmonary therapy in COPD care.Therefore, new airway clearance modalities are required to decrease the detrimental effects of accumulated secretions in COPD. One of the devices used in AC is the high frequency chest wall oscillation (The Vest). HFCWO involves the use of an inflatable vest/jacket that covers the chest and is attached to an air pulse-generating compressor which rapidly inflates and deflates the vest, producing oscillations to the chest wall of 5-25 Hz. Another new airway clearance modality is oscillating positive expiratory pressure(Quake) which combines PEP therapy with high frequency oscillations.
Chronic obstructive pulmonary disease (COPD) is a major cause of disability and mortality worldwide. This systemic disease progressively leads to dyspnea and exercise capacity impairment. Pulmonary rehabilitation effectively improves exercise capacity, dyspnea and quality of life in patients with COPD. However, its benefits progressively fade over time due to several factors such as the lack of regular exercise activity, dyspnea, airway secretions, hematosis impairment and acute exacerbations which can lead to hospitalization and accelerated muscle wasting. Nasal high flow (NHF) is a support used to deliver heated and humidified high flow air (up to 60 L/min) through nasal canula providing promising physiological benefits such as positive airway pressure or upper airway carbon dioxide washout. It can be used in association with oxygen and offers the advantage to overtake the patient's inspiratory flow, providing a stable inspired fraction of oxygen. Nasal high flow has widely been studied in pediatric and adult intensive care units and seems better than conventional oxygen therapy and as effective as noninvasive ventilation with regards to mortality to treat hypoxemic acute respiratory failure. More recently, several studies have shown that long-term nasal high flow could contribute to improve exercise capacity, dyspnea, airway secretion removal, hematosis, reduced acute exacerbations and subsequent hospitalizations in patients with COPD. Based on these results, the primary aim of this study is to assess whether long-term nasal high flow treatment can help COPD patients to better maintain their endurance capacity following a course of pulmonary rehabilitation.
In the presented study, autonomic function as well as risk for atrial fibrillation will be assessed to characterize the relation between risk of atrial fibrillation and autonomic function.
The aim of the study is to investigate the efficacy of upper limb exercise training in Chronic Obstructive Pulmonary Disease (COPD) patients. For the purpose of the study, a controlled trial will be conducted within Respiratory Clinic of Nicosia General Hospital. The sample will be divided in two groups. The intervention group will participate in a pulmonary rehabilitation program which includes upper and lower extremities exercises, with addition of arm ergometer. The second group (control group) will participate in the same program but without arm ergometer training. The study's hypothesis is that the intervention group will improve the outcome measures significantly better than the control group.
The purpose of conducting this study is to obtain PK data of Beclometasone Dipropionate (BDP)/Beclometasone-17-MonoPropionate (B17MP), Formoterol Fumarate (FF) and Glycopyrronium Bromide (GB) after inhalation of CHF 5993 in Japanese as well as Caucasian healthy subjects under the same setting.
This study will assess the within-day variation of blood eosinophils in patients with Chronic Obstructive Pulmonary disease (COPD) in stable state and determine if there is a correlation between the blood eosinophils and certain clinical parameters.
The VitaBreath (Philips, Respironics) is a portable, handheld, battery powered, non-invasive ventilation device, that has been shown by our group to reduce activity-related shortness of breath in patients with COPD. It delivers 18 cmH2O inspiratory and 8 cmH2O expiratory pressures, but can only be used during recovery periods. Our previous study (REC: 17/NE/0085) showed that use of the VitaBreath device during the recovery periods interspersing successive exercise bouts enhances exercise tolerance and reduces breathlessness compared to pursed lip breathing in patients with COPD. This was attributed to faster recovery from exercise-induced dynamic hyperinflation, assessed by volitional inspiratory capacity manoeuvres using a spirometer. However, inspiratory capacity manoeuvres are effort dependent, thus limiting the number of repetitions the patient can perform during exercise. In addition, investigation of the direct effect of the application of the VitaBreath device on dynamic hyperinflation was not possible due to the need to employ a spirometer for assessing inspiratory capacity. Optoelectronic plethysmography (OEP) allows continuous non-invasive assessment of end-inspiratory and end-expiratory volumes of the thoracoabdominal wall and its compartments, thereby facilitating assessment of dynamic hyperinflation on a breath-by-breath basis without the necessity to breathe via a spirometer. Unfortunately, OEP technology was not available at the time of our previous study. The investigators will use OEP to provide accurate breath-by-breath volume measurements during exercise and recovery to evaluate whether the VitaBreath device reduces total and compartmental thoracoabdominal wall volumes compared to the pursed lip breathing technique. Furthermore, the investigators will investigate the effect of use of the VitaBreath device on respiratory muscle activation and respiratory muscle oxygenation using OEP technology in conjunction with electromyography (EMG) and near inferred spectroscopy (NIRS), respectively to appreciate how the application of the VitaBreath device impacts on the operation and energy demands of the respiratory muscles as compared to control pursed lip breathing. The investigators hypothesised that the use of the VitaBreath device during the recovery periods interspersing successive exercise bouts will reduce the magnitude of dynamic hyperinflation in a greater extent compared to the pursed lip breathing technique.
Chronic Obstructive Pulmonary Disease (COPD) is characterized by chronic airflow limitation, a qualification of impairment of respiratory muscle function, including hyperinflation and muscle weakness. Thus, pulmonary rehabilitation is indicated for patients and is recommended for even the most severe cases. However some patients do not conclude conventional rehabilitation protocols, due to exercise intolerance, are then an electrical estimation and muscle training respiratory adjuvant treatments for patients. and little has been explored about the effects and methodologies of using transcutaneous electrical diaphragmatic stimulation (TEDS) in healthy subjects. The objective of this study on stage I is to evaluate the acute effect of transcutaneous electrical diaphragmatic stimulation on respiratory muscle strength, cardiac variability, thickness, resistance, mobility and diaphragmatic activation comparing different frequencies of electrical stimulation in healthy individuals.The objective of this study on stage II is to evaluate the effects of transcutaneous electrical diaphragmatic stimulation, compared to inspiratory muscle training (IMT) on respiratory muscle strength, lung function, thickness and diaphragmatic function in patients with exacerbated chronic obstructive pulmonary disease. The study was approved by the Research Ethics Committee of the Hospital de Clinicas of Porto Alegre (CAEE: 80271517.2.0000.5327).
The purpose of this study is to explore the role of low-dose immediate-release oral morphine as a novel adjunct pharmacotherapy to enable symptomatic adults with advanced chronic obstructive pulmonary disease (COPD) or interstitial lung disease (ILD) to exercise at higher intensities for longer durations and maximize the psycho-physiological benefits of a supervised exercise training program. We hypothesize that, compared to placebo, exercise training with oral morphine will result in relatively greater improvements in exercise endurance time and intensity ratings of perceived breathlessness during constant-load cardiopulmonary cycle exercise testing (CPET) at 75% of peak power output (PPO).
