A 10-year-old boy who is having an acute asthma attack is
brought to the ER. He is observed to be sitting up and struggling
to breathe. His breathing is accompanied by use of accessory
muscles, a weak cough, and audible wheezing sounds. His pulse
is rapid and weak, and both heart and breath sounds are distant
on auscultation. His parents relate that his asthma began to
worsen after he developed a "cold," and now he doesn't get relief
from his albuterol inhaler.

Explain the changes in physiologic function underlying his signs
and symptoms. - ANSWER-Recruitment of inflammatory cells
from the bloodstream into the bronchial wall, where they directly
attack the invading organisms and secrete inflammatory
chemicals that are toxic to the organisms causes airway
inflammation. Swelling of the bronchial wall, mucus secretion,
constriction of the airway; bronchial hyper-responsiveness to
stimuli causes airway obstruction or narrowing. They may discuss
on a cellular level as well:
Upon a trigger, the cascade of neutrophils, eosinophils,
lymphocytes, and mast cells cause epithelial injury. This causes
airway inflammation, which further increases hyperresponsiveess
and decreased airflow. Mast cells release histamine and
leukotrienes. These cause major bronchoconstriction,
inflammation, and mucus secretion. Mast cells can trigger multiple
cytokine release, which causes more airway inflammation. The
contraction of the airways and subsequent swelling leads to
further airway obstruction.
