Inspiratory trigger (nominal)
characteristics
Inspiratory trigger occurs when patient flow exceeds trigger setting.
Double limb with valve (flow trigger): 0.5 to 15.0 L/min
Single limb with valve or double limb with valve: 1.6 to 10.0 L/min (in five
steps)****
Single limb with intentional leak: 2.5 to 15.0 L/min (in five steps)
Expiratory cycle (nominal)
characteristics
Cycle occurs when inspiratory flow declines to the set percentage of peak
inspiratory flow.
5 to 90%
