Hb saturation with oxygen is mostly dependent on: (A) pO2, (B) pCO2, (C) HCO3-levels, (D) Hb %
Answer is A. Increased pH (decreased H+), decreased temperature, decreased PaCO2, and decreased 2,3-DPG will increase oxygen binding to the haemoglobin Ref: Biochemistry by U. Satyanarayana 3rd edition Pgno : 198,199
