what is the sensitivity equation
sensitivity = TP/ (TP+FN)
specificity =
TN/ (TN + FP)
postivie predictive value =
PPV = TP/ (TP + FP)
Negative predictive value =
NPV = TN/(FN + TN)
relative risk
[a/(a+b)] / [c/(c+d)]
attributable risk
[a/(a+b)] - [c/(c+d)]
hardy-weinberg =
p2 + 2pq + q2 = 1; p + q = 1
Henderson Hasselbalch =
pH = pKa + log(HCO3/0.03 PCo2)
volume of distribution =
amount of drug in the body/ plasma drug concentration
clearnace =
rate of elimination of drug/ plasma drug concentration
half life =
0.7 x volume of distribution/ CL
loading dose =
Cp x (CL/F)
CO =
rate of oxygen consumption/(arterial oxygen content - venous oxygen content)
CO =
SVxHR
MAP =
CO x TPR
MAP =
1/3 systolic + 2/3 diastolic
SV =
EDV - ESV
EF =
SV/EDV x 100
resistance =
driving pressure/ flow
resistance =
8n (viscosity)(length)/radius to the 4th x pi
Net filtration pressure =
(Pc-Pi) - (xc-xi)
GFR =
Uinulin x (V/Pinulin) = C inulin
Effective renal plasma flow =
Upah x (V/Ppah) = Cpah
Renal blood flow
RPF/(1-Hct)
Filtration fraction =
GFR/RPF
free water clearance =
V-Cosm
Physiological dead space
Vt x (Paco2 - PeCo2)/Paco2)
