Case Study 3
Disorders of Ventilation and
Gas Exchange
Emmanuel and his mother live
in an urban community housing complex. The building is worn down and dirty from
the urban dust, cockroaches, and mold. Emmanuel is five years of age and has
suffered from asthma for the last two years. One evening, his mother poured him
some milk and put him to bed. Shortly afterward, Emmanuel woke up wheezing and
coughing. As he gasped for air, he became more and more anxious. His mother ran
for his inhaler, but he was too upset and restless to use it. Emmanuel’s skin
became moist with sweat, and as he began to tire, his wheezing became quieter.
His mother called 911 and waited anxiously for the ambulance to arrive.
1. Emmanuel uses a corticosteroid inhaler for the
management of his asthma. What is the mechanism of action of this drug? How is
its action different from the ?2-agonist inhalants?
2. Why does someone with severe asthma become
physically fatigued during a prolonged attack? What are the physiological
events that occur during an attack?
3. One of the complications of respiratory fatigue is
the development of hypercapnia. How does the body compensate for an increase in
CO2? What are the effects of hypercapnia on the central nervous system?
