Sensitivity
Sensitivity = TP / (TP + FN)
Specificity
Specificity = TN / (TN + FP)
Positive predictive value
PPV = TP / (TP + FP)
Negative predictive value
NPV = TN / (TN + FN)
Relative risk
R = [a / (a+b)] / [c / (c+d)]
Attibutable risk
AR = [a / (a+b)] - [c / (c+d)]
Number needed to treat
1/absolute risk reduction
Number needed to harm
1/attributable risk
Hardy-Weinberg equilibrium
p^2 + 2pq + q^2 = 1
p + q = 1
Henderson-Hasselbach equation
pH = pKa + log ([HCO3]/0.03*PCO2)
Volume of distribution
Vd = amount of drug in the body / plasma drug concentration
Clearance
CL = rate of elimination of drug / plasma drug concentration
Half-life
t1/2 = (0.7*Vd) / CL
Loading dose
LD = Cp * Vd/F
Maintenance dose
MD = Cp * CL/F
Cardiac output
CO = rate of O2 consumption / (arterial O2 content - venous O2 content)
Cardiac output (physics eq.)
CO = HR * SV
Mean arterial pressure
MAP = cardiac output * total peripheral resistance
MAP = 1/3 systolic + 2/3 diastolic
Stroke volume
SV = end diastolic volume - end systolic volume
Ejection fraction
EF = (stroke volume / end diastolic volume) * 100
Resistance
R = driving pressure / flow = [8η (viscosity) * length] / (πr^4)
Net filtration pressure
Pnet = [(Pc - Pi) - (πc - πi)]
Glomerular filtration rate (conc. eq.)
GFR = U(inulin) * [V / P(inulin)] = C(inulin)
Glomerular filtration rate (pressure eq.)
GFR = Kf [(P(gc) - P(bs)) - (π(gc) -π(bs))]
Effective renal plasma flow
ERPF = U(PAH) * [V / P(PAH)] = C(PAH)
Renal blood flow
RBF = RPF / (1 - Hct)
Filtration fraction
FF = GFR / RPF
Physiologic dead space
V(D) = V(T) * (PaCO2 - PeCO2) / PaCO2
