Hemodynamic Interpretation

Question 1

What needs to be assessed first

Answer 1

CO/ CI

Question 2

If CO is low what problem is it

Answer 2

SV or HR

Question 3

What are the compensatory response of low CO

Answer 3

HR goes up (no hire than 150bpm though) and SVR increases

Question 4

How is SV assessed?

Answer 4

Preload, afterload, and contractility

Question 5

How do you assess preload?

Answer 5

RAP (R ventricular preload) and PCWP (L ventricular preload)

Question 6

What happens when the RAP and PCWP is low?

Answer 6

Indicates low circulatory volume or vasodilation of arterial bed (decrease SVR)

Question 7

What is the Tx for low RAP and PCWP?

Answer 7

Fluids and/or vasopressor

Question 8

What happens when the RAP and PCWP is high?

Answer 8

Indicates volume overload or contractility problem

Question 9

What is the Tx for high RAP and PCWP?

Answer 9

Inotrope for contractility.

Vasodilator, diuretics for overload depends on specific problem/

Question 10

How do you determine if its a contractility or volume overload problem is?

Answer 10

Look at clinical presentation of the patient.
