Answer

The act of respiration engages the following three processes:

  • Transfer of oxygen across the alveolus

  • Transport of oxygen to the tissues

  • Removal of carbon dioxide from blood into the alveolus and then into the environment

Respiratory failure may occur from malfunctioning of any of these processes. In order to understand the pathophysiologic basis of acute respiratory failure, an understanding of pulmonary gas exchange is essential.
