Which of the following statement (s) is/are true about Hb/02 dissociation curve?: (A) Foetal Hb shift curve to left, (B) Hypothermia shifts curve to left, (C) Hypercarbia shifts curve to left, (D) Acidosis shifts curve to left
Answer is B. A rise in temperature shifts the curve to the right so fall in temp. or hypothermia lead to shft to left PCO2 rises,(hypercarbia) the curve shifts to the right fall in pH (acidosis)shifts the curve to the right The fetal dissociation curve is shifted to the left due to high Hb content Ref: Ganong's Review of Medical Physiology Twenty-Third Edition Page No:611
