E-Trigger
(only in modes S and ST)
The E-Trigger depends on the respiratory
fl
ow and determines the sen-
sitivity for detecting expiration. It can be set to three levels.
1
60 % of max.
fl
ow value
2
70 %x of max.
fl
ow value
3
80 % of max.
fl
ow value
First set the I-Trigger. Then set the desired level using the programing
keys
and
. Press enter key
to con
fi
rm.
Frequency
(only in modes T and ST)
The frequency determines the breathes per minute (only in mode T or
in mode ST with apnea).
To set the frequency,
fi
rst go to the Clinic-menu. Then select
Fre-
quency
using the programing keys
and
. Now the device will
prompt you to enter the PIN. After entering the PIN set the desired
frequency using the programing keys
and
. You can set values
from 5 bpm to 30 bpm in 1 bpm-intervals. Press enter key
to con-
fi
rm. Next the parameter I:E is set.
I:E
(only in modes T and ST)
The ratio I:E determines the ratio of inspiration to expiration.
First set the frequency. Then set the desired inspiration time using the
programing keys
and
. Values between 0.4 s and 8.0 s can be set
in 0.1 s steps. To con
fi
rm, press the enter key
. The ratio I:E depends
on the set inspiration time. The delay time parameter is set next.
Delay Time
(only in mode ST)
The delay time is the time after which the device switches from S-mode
into T-mode in the event of breath failure.
First set the frequency and the inspiration time. Then set the delay time
using the programing keys
and
. Press enter key
to con
fi
rm.
You can set values from 0 sec to 20 sec in 1 sec-intervals.
