6-24

In AMV mode, you need to set the following basic ventilation parameters:

1. [O

%]: Oxygen concentration

2. [MV%]: Percentage of minute volume

3. [PEEP]: Positive end-expiratory pressure

4. [F-Trig] or [P-Trig]: Inspiration trigger level

5. [Exp％]: Expiration trigger level

6. [Tslope]: Time of pressure rising

6.6 Additional settings for ventilation

6.6.1 Sigh

Atelectasis can be prevented by activating the sigh function and setting the sigh in the form

of an intermittent PEEP. The purpose of expiratory sigh is to open collapsed areas of the lung

or to keep open "more dependent" areas of the lung.

The sigh function can be activated in V-A/C, P-A/C, PRVC, V-SIMV, P-SIMV, PRVC-SIMV

and AMV ventilation modes. When the sigh function is activated, the end-expiratory pressure

PEEP increases by the set value of Δint.PEEP.

The time between the two sigh phases can be set with [Interval].

[Cycles sigh] controls how many respiratory cycles are covered by the sigh phase. The

average airway pressure is higher, and a longer filling time is normally available.
