Description S T ST
Frequency
4 – 30 bpm
• • In T mode, setting the frequency sets
a fixed breathing rate for the machine
(trigger off). In ST mode as well as T
mode (trigger on), the set frequency
is defined as the minimum frequency,
which can be increased by sponta-
neous breaths of the patient.
Safety Frequency
On, Off
• In case of respiratory arrest of over
15 s, the patient is ventilated with
a frequency of 10 bpm and an I:E
ratio of 1:2.
Apnoea Time
0 – 60 s
•
The apnoea time is intended to give
the patient an additional period of
time to spontaneously breath once
the set frequency has lapsed. Apnoea
Time begins at the end of inspiration.
If the apnoea time is exceeded, the
device begins therapy with the set
frequency. If the apnoea time ends
before the set frequency has lapsed,
the apnoea time is ignored.
Inspiration Time
0.4 – 8 s
• • The inspiration time defines the dura-
tion of inspiration (in seconds). The
frequency must be taken into account
when setting the inspiration time.
Setting up a fixed inspiration time,
the I:E ratio is calculated depending
on the respiratory frequency.
Please note: In the system settings,
you can choose whether the inspira-
tion time or the I:E ratio can be set.
I:E
4.00: 1 – 1 : 4.00:
• • The I:E ratio is the ratio of inspiration
to expiration of a breath. When set-
ting up a fixed I:E ratio, the inspiration
time depends on the set frequency.
Please note: In the system settings,
you can choose whether the inspira-
tion time or the I:E ratio can be set.
Ti Max
1 – 10 s
• • • The "Ti Max" setting limits inspiration
time to prevent late switching to the
expiration phase.
