Formula for VO₂
10 x kg(3/4) = VO₂
Formula for VCO₂
8 x kg(3/4) = VCO₂
What does this formula describe?
[FiO₂ x (Pb - PH₂O)] - PaCO₂ / 0.8
Alveoar Gas/Air Equation
https://youtu.be/vrjK4gxa-48
Formula for arterial O₂ content/dL
(Hgb x 1.34 x SaO₂) + (PaO₂ x 0.003)
PBW (predicted body weight) equation for a male.
50 + 0.91(cm height - 152.4)kg = male PBW
PBW is used to determine your tidal volume (5 - 8cc/kg).
PBW (predicted body weight) equation for a female
45.5 + 0.91 (cm height -152.4)kg = female PBW.
PBW is used to determine your tidal volume (5 - 8cc/kg).
