Q

First what is SvO2??

A

Mixed Venous Oxygen Saturation

the % of Hb saturated with O2 in the mixed venous blood
Shows the balence b/t O2 delivery and consumption

Q

How does SvO₂ r/t CO? for example if CO high or low look at SvO₂, next if SvO₂ is high or low and it can tell you what patho is going on! so tell me what occurs in HIGH CO with Low and high SvO₂ and with LOW CO with Low and high SvO_2.

i know very confusing I don;t know how to write it look at the diagram and then memorize it and try to redraw it in your head!!!

Q

Ok so another confusing question but the diagram will show all you need to know.

You want to resuscitate your pt to a MAP of > 65mmHg what do you do using SvO₂!! start with normal SvO₂then go to low SvO₂!

Q

Explain what each wave numbered means is occuring

A

a- atrial pressure during contratction (atrial contraction)

C- bulging tricuspid early ventricular contraction (tricuspid valve closure)

x- downward movement of the ventricular during systole (atrial diastole)

V- venous return (atrial filling) against a closed tricuspid valve

Y- Tricuspid valve opening during diastole (atrial emptying)

Q

What does the PA catheter wave form look like as you insert it in

A

Narrowing of pulse pressure (“diastolic step up”) as the catheter enters the PA.

Loss of pulsatile trace as the catheter is advanced Through the PA and reflects the PCW
