Effect of Disodium Cromoglycate on Ventilation and Gas Exchange During Exercise in Asthmatic Children With a Postexertion FEVi Fall Less Than 15 Percent: Asthmatic Children

Pulmonary Function Tests: All children performed both tests without experiencing wheezing, cough, tightness of the chest or other respiratory complaints during and after the test. The results of lung function, expressed as percent of predicted, are presented in Table 1. Exercise Testing Results: The exercise testing results are summarized in Table 2. During the run,…

Effect of Disodium Cromoglycate on Ventilation and Gas Exchange During Exercise in Asthmatic Children With a Postexertion FEVi Fall Less Than 15 Percent: Cardiorespiratory and Metabolic Monitoring

Respiratory variables were measured by an open-circuit method minute ventilation (Ve, at body temperature, ambient pressure, and saturated with water) and respiratory rate were measured by a 10-L bell spirometer suitable for fast emptying (Biomedin). Oxygen uptake (V02 at temperature 0°C, pressure 760 mm Hg, and dry [O Water vapor]) and carbon dioxide production (Vcc>2,…

Effect of Disodium Cromoglycate on Ventilation and Gas Exchange During Exercise in Asthmatic Children With a Postexertion FEVi Fall Less Than 15 Percent: Exercise Testing

Spirometric measurements were performed at rest and at 5, 8, 11, and 15 min after the run. They included forced vital capacity (FVC), (FEVi), and forced expiratory flow between 25 and 75 percent of the expired vital capacity (FEF25-75%) measured by a 10-L bell spirometer (Biomedin, Padova, Italy). For this purpose, each child performed at…

Effect of Disodium Cromoglycate on Ventilation and Gas Exchange During Exercise in Asthmatic Children With a Postexertion FEVi Fall Less Than 15 Percent: Study Subjects

The children suffered from mild to moderate asthma with a duration of disease of 1 to 13 (7.5 ±3) years. All patients had a typical history of episodic breathlessness and wheezing and relief of symptoms with use of bronchodilators. None of the children was limited in daily life because of the disease, and most of…

Effect of Disodium Cromoglycate on Ventilation and Gas Exchange During Exercise in Asthmatic Children With a Postexertion FEVi Fall Less Than 15 Percent

Physical activity in children with asthma is generally encouraged and can be accomplished safely after pretreatment with inhaled drugs. An exercise bronchoprovocation test usually is utilized to evaluate the ability and safety for asthmatic children to engage in a physical exercise. This evaluation, however, does not reveal the consequences of disease on metabolic function when…

How to Improve Teaching About Asthma: A Look Toward the Future

The ALA has adopted the goal of making the Open Airways program a permanent part of every elementary school in the United States. To achieve this end, with the support of Fisons Pharmaceuticals, the program has been produced as an easy-to-read, easy-to-use kit costing $30 (US). It is comprised of a six-lesson curriculum with handouts…

How to Improve Teaching About Asthma: The US School Experience

The severity of asthma is often underestimated by patients and caregivers. Educating asthmatics directly would plausibly raise their expectations and encourage them to participate more meaningfully in their own care. In effect, physicians and other health providers would be educated indirectly via their patients’ improved understanding of asthma. The American Lung Association (ALA) has explored…
