2.8 - 7.7mmol/L
albumin
33-47 g/L
anion gap
15 - 20mmol/L
lactate
0.6 - 2.4 mmol/L
NOTE: >5mmol/L = lactic acidosis + tissue hypoxia
serum glucose

platelets
150 - 450 x 10^9/L
Hematocrit
42 - 47%
Hb
120 - 160 g/L
MAP
85 - 115mmHg
SVR
950 - 1300 dynseccm-5
normal and max safe ICP
10; max <20mmHg
normal pulse pressure
30 - 40mmHg
normal MAP and critical MAP for organ perfusion
normal 80 - 100mmHg
MAP < 60 mmHg can compromise organ perfusion
normal pulmonary artery pressures
sys / diastolic = 20-30/8-15mmHg
normal PCWP (indicates left ventricular end diastolic pressure)
4 - 12mmHg
anatomical deadspace
2ml/kg
normal CVP
2-6mmHg; also indicates right atrial pressure
normal C.O.
4 - 8L/min
normal C.I.
2.5-4L/min/m2
normal EF
65 - 70%
normal P/F ratio
400-500; <400 = pulm dysfunction
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
