Henderson-Hasselbalch Equation
pH= |
6.1 + log(HCO3/ 0.03 x PCO2)
|
|
Normal Anion Gap is...
Anion Gap= |
8-16mEq/mL
[Na]- ([Cl] + [HCO3]) |
|
In metabolic acidosis if anion gap is normal, acidosis is due to...
Why?? |
... decreased HCO3
Loss of HCO3 will be replaced with Cl- so anion gap remains the same |
|
In metabolic acidosis if anion gap is high, acidosis is due to...
Why?? |
... accumulation of acids
The anion gap will increase due to HCO3 binding to acids |
|

secretion; absorption |

filtration fraction=
|
GFR/RPF
|
|
Filtered load=
|
GFR x P(s) x % filterable (not plasma bound)
|
|
excretion rate=
|
U(s) x V
|
|
