1

Normal PA pressures are (mmHg)

15-25
--------
8-15

2

CVP reflects

Right atrial pressure

3

Pulmonary artery pressure reflects

Right and left side heart pressures

4

PA wedge pressure reflects

Preload of the left atrium

5

Normal range for cardiac output is

4-8 L/min

6

Normal range for PAWP is

8-12 mmHg

7

Normal range for CVP is

2-6 mmHg

8

Cardiac output is determined by

Heart Rate * Stroke Volume

9

SVR measures

Afterload of the left side of the heart

10

Pulmonary vascular resistance measures

Afterload of the right side of the heart

11

The dichrotic notch indicates

Closure of a valve (aortic or pulmonic)

12

A decrease in CVP may indicate

Vasodilation
Hypovolemia
Decreased venous return

13

An increase in CVP may indicate

Right side heart failure

14

A decrease in SVR may indicate

Distributive Shock (neurogenic, anaphylactic, septic)

15

An increase in SVR may indicate

Cardiogenic or Hypovolemic Shock

16

The "a" wave in a CVP waveform indicates __ and corresponds to what part of the ECG?

Rise in atrial pressure as a result of atrial contraction, corresponds with the PR interval

17

The "c" wave in a CVP waveform indicates __ and corresponds to what part of the ECG?

Rise in atrial pressure when AV valve closes, corresponds with mid/late QRS

18

The "v" wave in a CVP waveform indicates __ and corresponds to what part of the ECG?

Rise in atrial pressure as a result of ventricular contraction, corresponds with mid T wave

19

The "x descent" in a CVP waveform indicates __ and is seen where?

Atrial relaxation, the downslope of the "a" wave

20

The "y descent" in a CVP waveform indicates __ and is seen where?

Atrial emptying, the downslope of the "v" wave
