The purpose of the present study is to determine whether use of a small volume spacer is associated with better bronchodilatation in an unselected population of patients with documented reversible airflow limitations.
Administration of bronchodilator drugs with metered-dose inhalers (MDIs) is difficult for some patients because the timing of the spray and the inhalation must be coordinated exactly. Use of spacers seems to improve delivery in these patients. It is not clear, however, if there is any advantage to a spacer for patients who are able to use an MDI with correct technique.
The purpose of the present study is to determine whether use of a small volume spacer is associated with better bronchodilatation in an unselected population of patients with documented reversible airflow limitations. The intervention in the first part of the study is use of an MDI with or without a spacer to deliver a bronchodilator (2 puffs, 0.4 mg of fenoterol). Spirometry is performed before and after the inhalation.
The second part of the study is conducted identically to the first with the same conditions and variables but with the addition of rinsing the mouth with 100 mL of water after inhaling the bronchodilator but before the second spirometry measurement.
The outcome to be measured is the increase in forced expiratory volume in 1 second (FEV1) and forced expiratory flow rate (FEF25-75%).

Combined inhaled treatment with long acting adrenergics and steroids in an unique inhaler plays an important role in the management of non-mild asthma. Some studies have demonstrated that ...
The purpose of the study is to compare Symbicort pMDI with and without spacer in terms of steroid potency, improvement of lung function and asthma symptoms in children with asthma (6-11 ye...
Background: The bronchodilator therapy is an essential component of the management of asthma exacerbation. The delivery of bronchodilators to the lungs in asthma exacerbations is usually a...

The purpose of this study was to review the existing literature investigating carbohydrate mouth rinsing (CMR) as an ergogenic aid by using the effect sizes and percentage change in performance of the...
Oral carbohydrate rinsing has been demonstrated to provide beneficial effects on exercise performance of durations of up to one hour, albeit predominately in a laboratory setting. The aim of the prese...
There is good evidence that mouth rinsing with carbohydrate (CHO) solutions can enhance endurance performance (≥30 min). The impact of a CHO mouth rinse on sprint performance has been less consisten...

The volume of BLOOD passing through the HEART per unit of time. It is usually expressed as liters (volume) per minute so as not to be confused with STROKE VOLUME (volume per beat).
The volume of air contained in the lungs at the end of a maximal inspiration. It is the equivalent to each of the following sums: VITAL CAPACITY plus RESIDUAL VOLUME; INSPIRATORY CAPACITY plus FUNCTIONAL RESIDUAL CAPACITY; TIDAL VOLUME plus INSPIRATORY RESERVE VOLUME plus functional residual capacity; or tidal volume plus inspiratory reserve volume plus EXPIRATORY RESERVE VOLUME plus residual volume.
The balance of fluid in the BODY FLUID COMPARTMENTS; total BODY WATER; BLOOD VOLUME; EXTRACELLULAR SPACE; INTRACELLULAR SPACE, etc., maintained by processes in the body that regulate the intake and excretion of WATER and ELECTROLYTES, particularly SODIUM and POTASSIUM.
The volume of the HEART, usually relating to the volume of BLOOD contained within it at various periods of the cardiac cycle. The amount of blood ejected from a ventricle at each beat is STROKE VOLUME.
Asthma is caused by inflammation of small tubes, called bronchi, which carry air in and out of the lungs. If you have asthma, the bronchi will be inflamed and more sensitive than normal. When you come into contact with something that irritates your...
