HEMODYNAMIC

BLOOD PRESSURE

BLOOD PRESSURE = 120/80 mmHg
Mean Arterial Pressure (MAP)

MAP 93-96 mmHg
CVP - Central Venous Pressure

CVP = 2-6 mmHg (4-12 cmH2O)
PAP Pulmonary arterial pressure

PAP 25/8 mmHg ( mean 14)
PCWP - Pulmonary wedge pressure

PCWP = 4-12 mmHg
CO- Cardia Output

CO = 4-8 L/min
CI- Cardiac index

CI = 2.5-4.0 L/min
VO2- ejection fraction

VO2 = 250 ml/min
SVR - systemic vascular resistance

SVR = 20 mmHg/L/min or 1600 dynes/sec/cm^5-
PVR - Pulmonary Vascular resistance
- PVR = 2.5 mmHg /L/min
- or
- 200 dynes/ sec/ cm^5-
PULMONARY VASCULAR RESISTANCE

PVR = (MPAP-PWP)/CO
PAO2 =
- PAO2 =
- (Pb -P_H2O)FIO2 - (PaCO2 x1.25)
A-aDO2

PAO2- PaO2
CaO2

CaO2 =O2 in Rbc (Hb x 1.34xSaO2) + O2 in plasma( PaO2 x 0.003)
MAP
- MAP
- (2xdiatolic) + systolic / 3
Fick equation ( CArdiac Output)/ Qt

QT = VO2/ C(a-v)O2 x10

FIO2 present x Desired FIO2 / current PaO2
Desired Vt
Desired VE
Desired RR
- Desired Vt= (actual Vt x PaCo2)=desired Vt PaCO2)
- Desired RR = (actual RR x PaCO2) = (Desired RR x PaCO2)
