The pressure support is terminated as soon as the
inspiratory flow falls below a specific proportion of
the maximum inspiratory flow. The proportion of the
maximum inspiratory flow is defined with the trigger
criterion. The pressure support is also terminated
as soon as the duration of support exceeds the
maximum inspiratory time Timax.
When the pressure support is not switched on, the
patient's spontaneous breathing is supported by
the PEEP value set.
