What is the pH of blood under normal physiological conditions?
The pH of aerial blood is normally close to 7.40, with a normal range considered to be about 7.35 to 7.45. An aerial pH less than 7.35 is considered acidemia; an aerial pH greater than 7.45 is considered alkalemia. Under pathologic conditions the extremes of aerial blood pH have been noted to range as high as 7.8 and as low as 6.9. Ref: Levitzky M.G. (2013). Chapter 8. Acid-Base Balance. In M.G.
