Chapter 15 Flashcards
1
Q
3 sites of insertion
A
- Right internal jugular vein
- Left subclavian vein
- Femoral vein
2
Q
Pulmonary artery catheter
A
Directly measures: C.O., CVP, PAO, RAP, PAP, PAW, PCWP
Indirectly measures: SV, SVI, CI, PVR, SVR, RVSWI, LVSWI
Continuously monitors the pulmonary artery pressure
3
Q
CVP
A
0-8 mmHG
4
Q
RAP
A
0-8 mmHg L/min/m2
5
Q
PAP (right atrial pressure)
A
9-18 mmHg dynes x sec x cm5
6
Q
PCWP
A
4-12 mmHg dynes x sec x cm5
7
Q
CO/QT
A
4-8 mmHg L/min
8
Q
SV
A
60-130 ml
9
Q
CI
A
2.5-4.2 L/min
10
Q
PVR
A
20-120 dynes/sec/cm
11
Q
SVR
A
800-1500 dynes/sec/cm
12
Q
EF
A
50-75%
13
Q
Stroke Volume (SV)
A
SV = CO / HR
- vol of blood ejected by ventricles with each contraction
- major determinants: Preload (vol), Contractility (force), Afterload (resistance)
- change to ml
14
Q
Calculate: CI
A
CI = CO / BSA
15
Q
Calculate: PVR
A
PVR = PAP - PCWP / CO x 80
