<prompt> O2 delivery to tissues depends on all, exceptCardiac outputType of fluid administeredHemoglobin concentrationAffinity of hemoglobin for O2  <response>: 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
