Double triggering occurs when the ventilator inspiratory time
is shorter than the patient’s inspiratory time

24. Working principles of Adaptive Support
Ventilation (ASV) to maintain the target
minute ventilation:
- minimum work
- expiratory time = 3 TCD
r.Lluís
Blanch
25. ASV generates a PS support
breath with an automatically
adjusted PS level in order to
achieve the target combination
of VT and RR
Based on ETCO2 information,
MV is automatically adjusted
to keep ETCO2 within expert-
based acceptable ranges
