Hemodynamic Monitoring Flashcards
0
Q
What is afterload?
A
Resistance to ventricular ejection (elevated by Systemic vascular resistance (SVR))
1
Q
What is preload?
A
Ventricular end-diastolic pressure (elevated by RAP/CVP & PCWP)
2
Q
What is cardiac output
A
The amount of blood pumped by the heart each minute
Normal 4-6 liters
3
Q
What is stroke volume
A
Amount of blood pumped by the heart each beat.
Normal 60-130
4
Q
BPis the product of
A
Cardiac output x SVR
5
Q
Cardiac output is a product of
A
Heart rate and SV (co = hr x sv)
6
Q
Mean arterial pressure
A
MAP = systolic + (diastolic x2) / 3
Determines adequate perfusion
Normal 65-100
7
Q
Ejection fraction
A
EF = sv / end diastolic volume
Normal > 50 %
Amount of blood in the ventricle that is ejected during systole
