Live Monitoring Parameters
The following describes the Live Monitoring Parameters that are displayed on the eSeries ventilator screens.

Mve (L):
Minute Volume is the total exhaled volume for the last 60 seconds as calculated using the last 8 breaths.
-
The Mve will constantly change.
-
The value is recalculated and displayed at the end of exhalation phase.
-
When the unit is first turned on or resumed after pausing or making a mode selection, the Mve calculation will be based on every exhaled breath until the 8th exhaled tidal volume.
-
Once the 8th exhaled tidal volume is achieved the calculation will resume as stated above.
Vte (ml):
Tidal Volume is the volume exhaled by the patient in Mandatory, Spontaneous or Pressure Support Ventilation (PSV) breaths.
-
Vte is calculated based on the entire expired flow displayed as volume.
-
Vte is updated at the beginning of the next inspiratory phase (at the end of the exhalation phase).
Paw AV (cm H2O):
Paw AV is the average patient airway pressure measured during the last 60 seconds.
-
This measurement is monitored by the ventilator at all times and modes.
-
The number on display will be updated every 15 seconds.
Paw Peak (cm H2O):
Peak airway pressure is the maximum pressure measured during the inspiratory phase.
-
The number on the screen represents the maximum pressure during the mandatory inspiratory phase of Assist Control (A/CV), Spontaneous Intermittent Mandatory Ventilation (SIMV), BiLevel (BiLVL), and CPR modes.
-
In CPAP mode the maximum pressure during the spontaneous inspiratory phase is displayed.
-
The number is updated at the end of each inspiratory phase.
Rate (BPM):
Rate (BPM) is the rate at which the breaths are delivered in one minute.
-
The monitored breath rate is calculated by measuring the time interval (Tb means inspiration + expiration time) between 2 breaths.
-
Rate (BPM) equals 60 / Tb.
-
The number is updated after each breath.
-
The number is displayed for both mandatory and spontaneous breathing phases.
-
Mandatory means ventilator controlled.
-
Ventilation Waveform Display:
The ventilation waveform display provides a breath-by-breath visual representation of the breathing cycle. By pressing the Waveform Selection Button the waveform display will switch between pressure and flow ventilation waveforms on the screen.
