Question 1

Clearance

Answer 1

Cx= Ux * V / P x

Cx= Clearance of x (ml/ min)
Ux= Urine Conc. of x 
V= Urine Flow (ml/ min) 
Px= Plasma Conc. of x

Question 2

pK

Answer 2

pK= -logK

K= [H⁺]*[A^-]/ [HA]

Question 3

Henderson-Hasselbach

Answer 3

pH= pK + log [conjugate base]/ [acid]

pH= pK + log [HCO3^-]/ [H2CO3]

pH= pK + log [HCO3^-]/ 0.23 * [PCO2]

Question 4

Cerebral Perfusion Pressure

Answer 4

CPP= MAP- (ICP+CVP)

CPP= Cerebral Perfusion Pressure

MAP= Mean Arterial Blood Pressure

ICP= Intra-Cranial Pressure

CVP= Central Venous Pressure
