1

O2 content

CaO2 = (Hgbx1.34xO2 sat) + (0.003xPaO2)

2

Alveolar gas equation

PAO2 = (PB - PH2O)FiO2 - PaCO2/0.8

3

PVR

PVR = 80(mean PA - PCWP)/CO

4

SVR

SVR = 80(MAP-CVP)/CO

5

DO2 (oxygen delivery)

DO2 = CI x CaO2

6

CI

CI = CO/BSA

7

Mixed venous

SvO2 = SaO2 – [(VO2) / (Hgb x 1.36 x CO)]; SaO2: arterial oxygen saturation, VO2: oxygen consumption

8

VO2 (oxygen consumption)

(CaO2-CvO2) x CO

9

coronary perfusion pressure

CPP = DBP - LVEDP

10

Henderson-Hasselbach

pka = pH -log [base-]/[acid+]

11

maximal allowable blood loss

MABL = EBV[(starting Hct - target Hct)/starting Hct]

12

pRBCs volume to infuse

EBV[(target Hct-starting Hct)/(donor Hct-target Hct)]

13

pacemaker

Paced, sensed, response (I/T), rate modulation, multisite pacing

14

Dead space

(PaCO2 - PETCO2)/PaCO2
