O2 delivery to tissues depends on all, except: (A) Cardiac output, (B) Type of fluid administered, (C) Hemoglobin concentration, (D) Affinity of hemoglobin for O2
Answer is B. The oxygen dissociation curve can be shifted right or left by a variety of factors. A right shift indicates decreased oxygen affinity of haemoglobin allowing more oxygen to be available to the tissues. A left shift indicates increased oxygen affinity of haemoglobin allowing less oxygen to be available to the tissues Ref: guyton and hall textbook of medical physiology 12 edition page number:354,355,356
