thereby increases the oxygen-carrying capacity of the blood.
B Infection is not a clinical consequence of cyanosis.
C Although dehydration can occur in cyanotic heart disease, it is not a
compensatory mechanism for chronic hypoxia. It is not a clinical consequence of
cyanosis.
D Anemia may develop as a result of increased blood viscosity. Anemia is not a
clinical consequence of cyanosis.
