Normal capsular colloid osmotic pressure (CCOP) ?
0
What is normal Kf?
12.5 ml/min/mmHg
GFR=
Kf x Net Filtration Pressure

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
Formula for determining renal clearance
C(s) = (U(s) x V)/ P(s)
if C(s)= GFR then...
if >GFR then...
if < GFR then...
no net reabsorption or secretion;
secretion;
absorption
true renal plasma flow=
C(pah) /extraction ration
extraction ratio=
([renal artery]- [renal venous])/ [renal artery]
filtration fraction=
GFR/RPF
Filtered load=
GFR x P(s) x % filterable (not plasma bound)
excretion rate=
U(s) x V
normal GFR determined by inulin=
125 ml/min
Renal blood flow=
RPF/ (1-Hct)
