6 Ventilation Parameters
Parameter Name Description
Vexp Expired Volume or Tidal Volume
It is the tidal volume calculated by the expiratory flow
integration during the expiratory time
PEEP Positive End Expiratory Pressure) Is the pressure value at the end of the expiration
Pmax Maximum Pressure
Is the absolute maximum pressure value during the
inspiratory cycle
Vminute Minute Volume
Is the tidal (expiratory) volume multiplied by the
respiratory frequency
Freq Frequency (Respiration Rate) Is the respiration frequency (rate). (Tinsp + Texp)
-1
FiO
2
Inspired Fraction of Oxygen
Concentration
Is the oxygen concentration value in the gas mixture
in the measuring point (It is denominated FiO
2
–
Inspired O
2
Fraction when the measuring point is in
the gas mixture output connection of the ventilator to
the patient)
Tinsp Inspiratory Time Is the inspiratory time value (Positive Flow)
Texp Expiratory Time Is the expiratory time value (Negative Flow)
I:E I:E Ratio Is the result of Tins divided by Texp
Vinsp Inspired Volume
Is the volume resulting from the integration of inspired
flow during the inspiratory time
Fmax Maximum Flow
Is the maximum value of flow registered during the
inspiratory time
Fmin Minimum Flow
Is the minimum flow registered during the expiratory
time
Pmean Mean Pressure
Is the mean pressure during the entire respiration
cycle (Tins+Texp)
Pmin Minimum Pressure
Is the minimum pressure value registered during the
expiratory time
Pplat Plateau Pressure
Is the pressure value registered at the end of the
inspiratory flow
Csta Static Compliance
Is the result from the division of expiratory volume by
plateau pressure value
Cdyn Dynamic Compliance
Is the result from the division of expiratory volume by
maximum pressure value
Raw Airway Resistance Is the value of the airway resistance
