WebThe normal arterial blood pH range is between 7.36 and 7.44 ( [H+] between 44 and 36 nEq/L). Acidemia is defined as an arterial pH of less than 7.36 ( [H +] >44 nEq/L); it may result from a primary elevation in P co2 or a fall in [HCO 3− ]. Alkalemia is defined as an arterial pH greater than 7.44 ( [H +] <36 nEq/L).
