Exhaled tidal volume.
Exhaled tidal volume adjusted for patient weight.
Inspired tidal volume.
Inspired tidal volume adjusted for patient weight.
Spontaneous tidal volume.
Spontaneous tidal volume adjusted for patient weight.
Mandatory tidal volume: Displayed as a rolling average of either
8 breaths or one minute, whichever occurs first.
Mandatory tidal volume adjusted for patient weight.
Delivered machine volume measured by the ventilator's inspiratory
flow sensor.
Percent leakage: The difference between the inspired and exhaled
tidal volumes in terms of % difference.
Minute volume. Volume of gas exhaled by the patient during the
last minute.
Minute volume adjusted for patient weight.
Spontaneous minute volume.
Spontaneous minute volume adjusted for patient weight.
Breath rate.
Spontaneous breath rate.
Inspiratory time.
Exhalation time.
Inspiratory/expiratory ratio.
Note: Not active for demand breaths.
Rapid shallow breathing index.
Peak inspiratory pressure.
Note: Not active with spontaneous breaths.
Mean airway pressure.
Plateau pressure. If no plateau occurs, then the monitor displays.
Positive end expiratory pressure.
Air inlet gas supply pressure.
Oxygen inlet gas supply pressure.
Delivered percent O
Dynamic compliance (CDYN and CDYN/Kg), absolute and
normalized to patient weight.
