Term
Sensitivity
Definition
Sensitivity = TP/(TP+FN)
Term
Specificity
Definition
Specificity = TN/(TN+FP)
Term
Positive predictive value
Definition
PPV = TP/(TP+FP)
Term
Negative predictive value
Definition
NPV = TN/(TN+FN)
Term
Relative risk
Definition
R = [a/(a+b)]/[c/(c+d)]
Term
Attributable risk
Definition
AR = [a/(a+b)] - [c/(c+d)]
Term
Number needed to treat
Definition
1/absolute risk reduction
Term
Number needed to harm
Definition
1/attritutable risk
Term
Hardy-Weinberg equilibrium
Definition
p^2 + 2pq + q^2 = 1

P+q = 1
Term
Henderson-Hasselbalch equation
Definition
pH = pKa + log [HCO3-]/(0.03 pCO2)
Term
Volume of distribution
Definition
Vd = amount of drug in the body/plasma drug concentration
Term
Clearance
Definition
CL = rate of elimination of drug/plasma drug concentration
Term
Half-life
Definition
t(1/2) = 0.7 x Vd / CL
Term
Loading dose
Definition
LD = Cp x Vd/F
Term
Maintenance dose
Definition
MD = Cp x CL/F
Term
Cardiac output
Definition
CO = rate of O2 consumption / (arterial O2 content - venous O2 content)
Term
Cardiac output
Definition
CO = stroke volume x heart rate
Term
Mean arterial pressure
Definition
MAP = cardiac output x total peripheral resistance

MAP = 1/3 systolic + 2/3 diastolic
Term
Stroke volume
Definition
SV = end diastolic volume - end systolic volume
Term
Ejection fraction
Definition
EF = stroke volume/end diastolic volume x 100
Term
Reisstance
Definition
R = driving pressure/flow = 8(viscosity) x length / (pi*r^4)
Term

Definition
Pnet = [(Pc - Pi) - (PIc-PIi)]
Term
Glomerular filtration rate
Definition
GFR = U(inulin) x V/P(inulin) = C(inulin)
Term
Effective renal plasma flow
Definition
ERPF = U(PAH) x V/P(PAH) = C(PAH)
Term
Renal blood flow
Definition
RBF = RPF / (1-Hct)
Term
Filtration fraction
Definition
FF = GFR/RPF
Term
Physiologic dead space
Definition
VD = VT x (PaCO2 - PeCO2)/PaCO2
