Filter by:An abnormally high V̇E/V̇CO2 response to exercise is a key pathophysiological feature of patients with chronic cardiopulmonary disease that is associated with adverse health outcomes. It follows that any intervention capable of decreasing the V̇E/V̇CO2 response to exercise has the potential to improve clinical and/or patient-reported outcomes. The investigators of this trial will compare the effects of orally administered sodium chloride (4 g, placebo) and sodium bicarbonate (0.3 g/kg of body mass) on ventilation, breathing pattern, dynamic operating lung volume, gas exhange, cardiovascular, metabolic and symptom parameters during symptom-limited, high-intensity, constant-work-rate cycle exercise testing in healthy adults aged 20-40 years.
The main objective of this study is to demonstrate that the only administration of L-citrulline, can improve immune functions in critically ill patients at high risk of nosocomial infection.
The purpose of the present study is to determine the utility and effectiveness of combined inspiratory (IMT) and expiratory muscle training (EMT) in improving ventilatory function in people who are disabled by long-term stroke (greater than 8 months following onset) with hemiparesis or hemiplegia. xx subjects will be randomized into 2 parallel groups in which the experimental group will undergo combined IMT and high-resistance EMT and the comparison group will undergo IMT with low- resistance EMT. Both training techniques involve breathing through a tube with known amounts of resistance. Subjects will perform the breathing maneuvers for 10 repetitions, twice daily, 5 days per week for 4 weeks, in the home environment. Adherence will be monitored by reminder telephone calls at least weekly. Outcomes will be assessed using maximum inspiratory and expiratory pressures and standard pulmonary function testing.
The ventilation (respiratory rate, tidal volume and end-tidal CO2) was monitored for patients receiving procedural sedation during endoscopy procedures in order to observe what changes commonly occur.
