Patients with moderate to severe anaemia have a reduced

A. False   Output rises to compensate for the blood’s reduced O2 carrying capacity.

B. False   Bruits are common since increased flow velocity and decreased blood viscosity increase the likelihood of turbulent flow.

C. False   2:3-DPG is increased, shifting the dissociation curve to the right so that blood gives up its oxygen more easily.

D. False   Arterial PO2 is normal; it is O2 content which is reduced.

E. True   Due to the reduced capacity to deliver O2 to the muscles.
