hemodynamic monitoring Flashcards
1
Q
What is the normal central venous pressure range?
A
2-8 mmHg
- measures preload or right atrial pressures
2
Q
Which type of hemodynamics monitoring measures preload?
A
Central venous pressures (CVP)
- normal -> 2-8 mmHg
3
Q
A low central Venus pressure (CVP) or 2 > CVP is indicative of what?
A
- decreased preload or blood return to the heart is low
- hypovolemia
- decreased peripheral Venus resistance due to vasodilation
- distributive shock
4
Q
A high central Venus pressure (CVP) or 8 < CVP is indicative of what?
A
- fluid overload
- pericardial tamponade
- pleural effusion
- pneumothorax
5
Q
What is the normal Pulmonary capillary occlusion/wedge pressures (PAOP/PCWP) range?
A
4 - 12 mmHg
6
Q
What is the normal pulmonary pressure (PAP) range?
A
- systolic = 15-30 mmHg
- diastolic = 5-15 mmHg
- mean PAP = 8-20 mmHg
7
Q
What does the a high pulmonary artery pressure (PAP) indicate?
A
- PAP > 30/15 or mean PAP > 20
- lung damage (COPD, fibrosis)
- pulmonary embolism, causes blockage in the lung
- left sided heart failure, causes back up into in the lungs
- valve disease, regurg causes back up into the lungs
8
Q
What is the normal cardiac output range?
A
4-6 liters/minute
9
Q
What is the normal cardiac index?
A
2.5 - 4.2 liters/minute
10
Q
What is the normal ejection fraction (EF)?
A
60-70%
11
Q
A
