WebAbstract. There has been considerable interest over the last years in gas exchange abnormalities that occur in patients with bronchial asthma, particularly during an acute attack. These are essentially characterized by moderate to severe hypoxemia and hypocapnia caused by considerable ventilation-perfusion (VA/Q) mismatch. WebAs the blood is pumped through this capillary network, gas exchange occurs. Although a small amount of the oxygen is able to dissolve directly into plasma from the alveoli, most of the oxygen is picked up by erythrocytes (red blood cells) and binds to a protein called hemoglobin, a process described later in this chapter.
