A decrease in which of the following parameters will shift the O2 dissociation curve to the right?: (A) pH, (B) Paial pressure of CO2, (C) 2,3 DPG concentration, (D) Temperature
Answer is A. Left shift (high affinity for O2) Right shift (low affinity for O2) Temperature decrease increase 2.3-DPG decrease increase p(CO2) decrease increase p(CO) increase decrease pH (Bohr effect) increase (alkalosis) decrease (acidosis) Type of haemoglobin Fetal haemoglobin Adult haemoglobin
