12-16 g/100ml of blood, (no anemia or >10g for weaning)
*Ct
Tube compliance aka compressible volume, volume lost to pt circuit, approx 3ml/cmH20 x PIP, deduct from VT to find actual delivered tidal volume. VT-(PIP x 3) equals actual VT.
CVP
central venous pressure, norm 2-6 mmHg, 2-6 weaning
PaO2-to decrease while pt on mech vent
<PIP, <RR, <PEEP, or <FIO2
TLC
total lung capacity 6L
MIP/NIF
Max Inspiratory Press, norm -80 - -100, > -20 support indicated, <-20 weaning (remember that negative numbers are larger as they become less, -25 < -20)
RV
Residual Volume 1.2 L
CcO2
Content of pulm capillary blood oxygen at 100% FIO2, (Hbx1.34)1 + (PAO2x.003) used in shunt equation
