How do you calculate Vt or Tidal Volume
- if in lbs divide by 2.2 and multiply by 10
- if in kg, just mulitply by 10
How do you calculate Vds or deadspace volume?
- if in lbs, mutiply by 1
- if in kg, multiply by 2
How do you calculate Va?

Vds - Vt = ?ml
how do you calculate VA?
- (Vt-Vds)*RR = ?L/min
- Va * RR(f) = ? L/min
How is VE calculated?
- Vt *RR or f = ? L/min
- dont forget to divide by 1000 or move 3 decimal places
Lung compliance or Cl is calculated how?

Vt / P then convert to L/cmH2O by moving 3 decimal places
How is Raw calculated?

P/F = ? cmH2O/L/sec
How is Vd/Vt calculated?

PaCO2 - PeCO2 / PaCO
