What is the pH range for Acidosis & Alkalosis?
|
<7.35 is acidosis, >7.45 is alkalosis
|
|
|
What is a buffer?
|
a chemical that resists sudden changes in pH, contains a weak acid and its salt or a weak base and its salt
|
|
|
What is the henerson-hasselbach equation?
|
pH=pKa + log([A-]/[HA])
|
|

Carbonic Acid-Bicarbonate buffer system
|
|
|

|
What is the ratio of bicarbonate to carbonic acid when plasma pH is normal?
|
ph will = 7.4, thus buffer ratio is 20/1
|
|
|
What effects blood pH
|
change in bicarbonate concentration of the PCO2

|
proton acceptor form [HPO42-]
