Triggering via internal sensors
Triggering via FlowCheck sensor
Inspiratory trigger (3 levels):
• Level 1: Sensitive, corresponds to approx. 3 l/min
• Level 2: Medium sensitivity, corresponds to approx. 5 l/min
• Level 3: Insensitive, corresponds to approx. 10 l/min
Expiratory trigger (3 levels):
• Level 1: Long ASB breath, corresponds to approx.
10 % of the inspiratory maximum flow
option)
• Level 2: Medium ASB breath, corresponds to approx.
35 % of the inspiratory maximum flow
• Level 3: Short ASB breath, corresponds to approx.
70 % of the inspiratory maximum flow
Inspiratory trigger (units):
1 l/min to 15 l/min
Expiratory trigger (units)
5 % flow max. to 80 % flow max.
Inspiratory trigger (5 levels):
• Level 1: Very sensitive (only slight pressure on the chest
is necessary to trigger a mechanical breath)
to
• Level 5: Insensitive (firm pressure on the chest is necessary
to trigger a mechanical breath)
