Exercise-induced asthma is a feeling of shortness of breath, with the presence of cough, wheezing, and chest tightness after physical effort.

Normally the bronchial tree responds to exercise with increasing radius of the interior of the bronchi (bronchodilation), but those affected by exercise-induced asthma occurs otherwise narrow and produces bronchoconstriction.

CAUSES
The exercise-induced asthma (EIA) is due to cooling and drying air relative (loss of H2O) by increased ventilation during exercise. The cooling and drying cause changes in the osmolarity of the mucosa, leading to one hand, there is a mast cell degranulation with release of mediators, and second, to the occurrence of direct vagal stimulation. The result is the emergence of bronchoconstriction. Cold air inspired Low humidity of inspired air, Loss of heat from the air. Exercise-induced asthma Read the rest of this entry »

Asphyxia is a condition that results when the respiratory exchange between the air sacs of the lungs and blood is interrupted or the highest degree difficult. As a result of partial or complete withdrawal, rapid or gradual oxygen anoxemia occurs.
