Hemodynamic Parameters

Question 1

Central Venous Pressure (CVP)

Answer 1

2 - 6 mmHg

Question 2

Cardiac Index (CI)

Answer 2

2.5 - 4.2 L/min

Question 3

Cardiac Output (CO)

Answer 3

4 - 8 L/min

Question 4

Systemic Vascular Resistance (SVR)

Answer 4

800 - 1200 dynes

Question 5

Pulmonary Artery Wedge/Occl Pressure (PAO/WP)

Answer 5

6 - 12

Question 6

What dose a low CVP indicate?

Answer 6

Hypovolemia

Question 7

What does a high CVP represent?

Answer 7

Over-hydration or heart failure; cardiogenic shock

Question 8

What does a low CI reveal?

Answer 8

Acutely low levels = cardiogenic shock

Question 9

A low CO could mean…

Answer 9

Hypovolemia; blood/fluid loss

Question 10

A high CO could mean:

Answer 10

Hypervolemia

Question 11

A high PAOWP…

Answer 11

increased fluid; decreased ventricular elasticity

Question 12

What is the PAWP or PCWP?

Answer 12

A measure of systolic and diastolic pressures in the left ventricle at end diastole

Question 13

What does the CVP measure?

Answer 13

The pressure exerted by fluid in the right atrium.

Question 14

What is the SVR?

Answer 14

The resistance provided by the systemic circulation against which the left ventricle must pump blood…
