Real ventilation time
Minute volume (MV) = respiratory frequency x tidal volume (
Real ventilation time (min) =
Example:
O content = 1000 l; f = 10; V
2
This gives the following equation:
Real ventilation time (min) =
Real Demandflow time
Example:
Inhalation flow 45 l/min
Patient data:
Inspiration: Expiration (I : E) = 1 : 2
Respiratory frequency = 10 min
Tidal volume (V ) = inhalation flow x inhalation time
t
For the above example:
Tidal volume (V ) = 45 l/min x 0.033 min= 1.5 l
