7 Monitoring
TE
(s)
Monitoring 1 Expiratory time. In mandatory breaths, TE is
measured from the start of exhalation until the
set time has elapsed for the switchover to inspi-
ration. In spontaneous breaths, TE is measured
from the start of exhalation, as dictated by the
ETS setting, until the patient triggers the next
inspiration. TE may differ from the set expira-
tory time if the patient breathes spontaneously.
TI
(s)
Monitoring 1 Inspiratory time. In mandatory breaths, TI is
measured from the start of breath delivery until
the set time has elapsed for the switchover to
exhalation. In spontaneous breaths, TI is mea-
sured from the patient trigger until the flow
falls to the ETS setting, for the switchover to
exhalation. TI may differ from the set inspira-
tory time if the patient breathes spontaneously.
Time
before
starting SBT
SBT Controls Quick Wean parameter. Defines the length of
time that patient conditions must meet the
To
start
criteria, while %MinVol is reduced to a
minimum of 70%, before an automated spon-
taneous breathing trial (SBT) will start.
For details, see the Quick Wean chapter in the
INTELLiVENT

-ASV manual.
Time bet-

SBTs
SBT Controls Quick Wean parameter. Defines the minimum
length of time that must pass between two
automated spontaneous breathing trials (SBT).
