Vte xxx ml
The Exhaled Tidal Volume (Vte) monitor displays the tidal volume as measured at the patient wye.
Vte data is recalculated and displayed at the completion of every exhalation.
VE xx.x L
The Minute Volume (VE) monitor displays the exhaled tidal volume for the last 60 seconds as
calculated from the last 8 breaths. VE data is recalculated and displayed at the completion of every
exhalation or every 20 seconds, whichever occurs first.
I:E xx:xx
The I:E Ratio displays the unitless ratio between measured inspiratory time and measured exhalation
time. The smaller of the inspiratory and exhalation times is normalized to one. Both normal and
inverse I:E Ratios are displayed.
NOTE
In normal ventilation, I:Ecalc (calculated I:E ratio) is displayed while changes are being made to the
Inspiratory Time or the Breath rate values.
REMARQUE
En mode de ventilation normale, IEcalc (ratio I:E calculé) est affiché pendant que des changements
sont apportés aux valeurs Durée inspiratoire ou Rythme respiratoire.
I:Ecalc xx:xx
The Calculated I:E ratio (I:Ecalc) display is based on the set Breath Rate and Inspiratory Time. The
display is updated in real-time while either setting is being changed. In modes where Vcalc is
displayed during Inspiratory Time changes, the display can be toggled between Vcalc and I:E calc
using the Select button.
Vcalc xxx Lpm
The Calculated Peak Flow is based on the Tidal Volume and Inspiratory Time settings. Vcalc is
included in the list of monitored values when Volume ventilation is selected, and is not included when
pressure ventilation is selected. Vcalc is automatically displayed when Tidal Volume or Inspiratory
Time
37
is selected for change. When both controls are deselected, the previously displayed monitored
data will be restored to the display window.
37
Vcalc is only displayed while Inspiratory Time is selected if Volume Mode is selected. Vcalc is displayed any
time Tidal Volume is selected regardless of the current ventilation mode.
