<prompt> Which of the following statement s isare true about Hb02 dissociation curve?Foetal Hb shift curve to leftHypothermia shifts curve to leftHypercarbia shifts curve to leftAcidosis shifts curve to left  <response>: 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 acidosisshifts the curve to the right The fetal dissociation curve is shifted to the left due to high Hb content Ref: Ganongs Review of Medical Physiology Twenty-Third Edition Page No:611
