Q
CVP measurement
A
Not routinely measured anymore
Surrogate of RA pressure (pre load)
Change in CVP measured with 5 min after fluid bolus
0-3 preload low
3-5 preload normal
5-7 preload high

Complications of CVC
A
10
Q
Pulse Pressure Variation
A
Irregular cardiac rhythm influences stroke volume and pulse pressure
11
Q
Passive leg raise
A
Increase pulse pressure >10% likely fluid responsive
250-500mL from the legs
Caveat: patient must have 2 legs
