Evil Hemodynamics

Question 1

Normal cardiac output in L/min

Answer 1

4-8 L/min

Question 2

Normal cardiac index

Answer 2

2.5 - 4

Question 3

Normal stroke volume

Answer 3

50-100 mL/beat

Question 4

Normal Sv02 (mixed venous — from Swan)

Answer 4

60-75%

“Although mixed venous O2 saturation (SvO2) accurately indicates the balance of O2 supply/demand and provides an index of tissue oxygenation, the use of a pulmonary artery (PA) catheter is associated with significant costs, risks and complications. Central venous O2 saturation (ScvO2), obtained in a less risky and costly manner, can be an attractive alternative to SvO2.”

Question 5

Normal Scv02

Answer 5

> 70% (70-85%)

Question 6

Normal pulmonary artery pressure

Answer 6

“Quarter over dime”
25/10

Question 7

Normal PAOP (“wedge” pressure)

Answer 7

“Dime”
8-12 mm Hg

Question 8

Normal RAP/CVP

Answer 8

“Nickel”
2-6 mm Hg

Question 9

Normal SVR

Answer 9

900-1400

Question 10

______ is calculated by dividing cardiac output by body surface area.

Answer 10

Cardiac index
