Cardiovascular data and Hemodynamics formulas

2.5-4.2 Lmin-1.m2

4-7 L/min

46 +/- 5 ml/m2

12-15 mmHg

20-30/8-12 mmHg

5-12 mmHg

270 +/- 15 dyne.s/cm5.m2

1680-2580 dyne.s/cm5.m2

• -2 to +6 mmHg
• (20-25 mmHg= too much fluid)(increased during mech vent pts because higher
• intrathoracic pressure)

80-95 mmHg

• = Arterial O2 Content (ml O2/dL)= 1.36 (Hgb)(SaO2) + 0.003 PaO2
• (SaO2 = Arterial O2 Saturation)

= O2 Delivery(ml O2/min)= CO x CaO2 x 10



= mixed Venous O2 Content (ml O2/dL)= 1.36 (Hgb)(SvO2) + 0.003 PaO2

(SvO2 = mixed Venous O2 Saturation)

= CI (CaO2-CvO2)

= (CaO2-CvO2)/ CaO2
