50 - 110umol/L
10
Q
urea (BUN)
A
2.8 - 7.7mmol/L
11

anion gap
A
15 - 20mmol/L
13
Q
lactate
A
0.6 - 2.4 mmol/L
NOTE: >5mmol/L = lactic acidosis + tissue hypoxia
14
Q
serum glucose
A
4-8 mmol/L
15
Q
RBC
A
4.5 - 5.5 x 10^12/L
16
Q
WBC
A
6 - 10 x 10^9/L
17
Q
platelets
A
150 - 450 x 10^9/L
18
Q
Hematocrit
A
42 - 47%
19
Q
Hb
A
120 - 160 g/L
20
Q
MAP
A
85 - 115mmHg
21
Q
SVR
A
950 - 1300 dynseccm-5
22
Q
normal and max safe ICP
A
10; max <20mmHg
23
Q
normal pulse pressure
A
30 - 40mmHg
24
Q
normal MAP and critical MAP for organ perfusion
A
normal 80 - 100mmHg
MAP < 60 mmHg can compromise organ perfusion
25
normal pulmonary artery pressures
sys / diastolic = 20-30/8-15mmHg
26
normal PCWP (indicates left ventricular end diastolic pressure)
4 - 12mmHg
27
anatomical deadspace
2ml/kg
28
normal CVP
2-6mmHg; also indicates right atrial pressure
29
normal C.O.
4 - 8L/min
30
normal C.I.
2.5-4L/min/m2
31
normal EF
65 - 70%
32
normal P/F ratio
400-500; <400 = pulm dysfunction
33
normal P(A-a)O2 and normal PaO2/PAO2. Which is better indicator of shunt?
P(A-a)O2 = 10-15mmHg <60y.o. or 25-35 >60y.o.
PaO2/PAO2 = 0.75-1
Ratio is better indicator of shunt bc it is not dependent on age or FiO2
