Perfusion good
2
Q
Deadspace
A
Air
No perfusion
3
Q
CvO2
A
(1.34HgbSvO2) + (PaO2 * 0.003)
4

A
Q = 5
BSA = 1.7
5
Q
O2ER
A
(CaO2 - CvO2) / CaO2
OR
**(SaO2-SvO2)/SaO2 **
6
Q
VO2
A
200-250 mL O2/min
7
Q
VO2I
A
120-150 O2/min/1.7
8
Q
What does O2ER represent?
A
Oxygen consumption, should be less than 30%
9
Q
Right Shift
A
Decreased affinity, everything is high (4R), can’t pick up, easy drop off
10
Q
Left Shift
A
Increased affinity, everything is low (4R), picks up everything, drops off nothing
