Active clinical trials for "Respiratory Aspiration"

Τherapeutic equivalence, randomized, multiple-dose, placebo-controlled, observer-blind, parallel group design consisting of a 2-week run-in period followed by a 4-week treatment period with Fluticasone propionate 100 mcg and Salmeterol 50 mcg inhalation powder/Respirent Pharmaceuticals (Test) or ADVAIR DISKUS® 100/50 mcg (Reference) or placebo.

Albuterol is the most commonly used β agonist to treat reversible lower airway obstruction. Albuterol contains a racemic mixture of two enantiomers. Levalbuterol contains the single R form enantiomer. Levalbuterol is frequently prescribed to limit cardiovascular toxicity. The investigators sought to examine the changes in oxygen consumption (V'O2) and Heart Rate (HR) following administration of albuterol and

Up to 50% of infants and young children cry during the administration of their inhaled treatment for their asthma. This results in decreased lung deposition, and thus decreased effectiveness of their inhaled treatment. The objective of this study is to evaluate whether animated cartoons can increase the cooperation of young children with asthma who are not cooperative during the delivery of their ICS therapy through a pMDI/spacer.

According to the World Health Organization cigarette smoking is today one of the leading single causes of preventable death and morbidity. The electronic cigarette (e-cigarette) has been marketed as a safer alternative to conventional cigarettes, and its global sales continue to grow exponentially each year. Despite growing e-cigarette use, scientific data on health effects are insufficient in some respects and completely lacking in others. Therefore the current study is designed to investigate the effects of active e-cigarette inhalation on the cardiovascular and respiratory systems.

The standard procedure used for airway control in general anesthesia for LC (laparoscopic cholecystectomy) is endotracheal intubation (EI). AuraGain and I-Gel are supraglottic airway devices (SADs) used for airway control for certain types of surgeries. The aim of this study was to evaluate and compare the performances of new types of SADs with EI regarding their insertion times, durations, perioperative complications and effects on hemodynamic parameters and peak airway pressures (Paw) in LC as well.

The study will assess how the inhalation technique used (deep inhalations versus tidal breathing) influences the results of a mannitol challenge test and a methacholine challenge test, if at all.

Patients affected with severe parenchymal pulmonary diseases, such as Chronic Obstructive Pulmonary Disease (COPD ), may experience dyspnea at rest due to increased work of breathing and reduced oxygenation. The delivery of high-flow humidified nasal oxygen (HFNC) has been shown to have a positive-end-expiratory pressure (PEEP) effect and is able to flush out CO2 from the upper airways, reducing dead space ventilation. Furthermore it has been proven to reduce the respiratory rate shortly after its initiation. These multiple actions offer the potential of changing the respiratory pattern and reducing work of breathing, improving the efficiency of breathing. In this short-term, physiological, open, randomized, cross-over pilot study the investigator swill describe the effects of varying settings of high-flow nasal oxygen on respiratory rate, tidal volume, and diaphragmatic work of breathing in patients with severe COPD. The investigators will also describe changes in gas exchange and effects on the subjects' comfort and dyspnea and the breathing responses to varying setting of CPAP in the subject population.

Preoxygenation optimizes oxygen content in the functional residual capacity (FRC). Adequate preoxygenation is defined by an expiratory oxygen fraction (FEO2) > 90%. Inspiratory support and positive end expiratory pressure (PEEP) can create a better reservoir, improve gas exchange and shorten the time needed for adequate preoxygenation. The goal of the study is to evaluate the efficacy and tolerability of different levels of inspiratory support and positive end expiratory pressure during preoxygenation in healthy subjects.

Inspiratory muscle weakness, limited functional exercise capacity and worse quality of life have been shown in patients with exacerbation of chronic obstructive pulmonary disease (COPD). Recommendations from clinical practice guideline state that promoting pulmonary rehabilitation after exacerbation can improve the conditions above. Inspiratory muscle training (IMT) has been proven to enhance inspiratory muscle strength and endurance in patient with stable COPD. However, there is less research on whether IMT in addition to pulmonary rehabilitation after exacerbation can benefit inspiratory muscle function, functional exercise capacity and quality of life in patients with COPD. The purpose of this study is to examine the effects of IMT in addition to pulmonary rehabilitation on respiratory muscle function, functional exercise capacity and quality of life in patients with exacerbation of chronic obstructive pulmonary disease.

The purpose of this study is to better understand specific stress-management practices on mood, sleep, and physiology. Participants will be assigned to one of three interventions (they all active interventions - none are a "wait-list"). Each intervention asks participants to engage in a daily practice of 20 minutes per day for 8 weeks. Questionnaires and measures of heart rate and blood pressure will be collected at the start and end of the 8 weeks, including a virtual laboratory visit.
