Weinmann MEDUMAT Standard2 Instructions

Pressure support and the
expiration trigger
Pressure support ΔpASB
The pressure support is always given as a value above PEEP. In addition to the set
PEEP, a patient receives this as soon as the inspiration trigger has been detected.
Example calculation:
PEEP = 5mbar, ΔpASB = 10mbar inspiration pressure in the inhalation phase = 15mbar
Trigger level Corresponding unit value
Level 1 (long) Approx. 10% Flow max
Level 2 (medium) Approx. 35% Flow max
Level 3 (Short) Approx. 70% Flow max
Expiratory trigger
Initiate expiration as soon as the ow to the patient is only the set value (in %) with
respect to the maximum ow. The length of the pressure support is set with the
expiratory trigger.
Trigger sensitivity: 5-80% of max. ow. In principle, the following applies: the smaller
the % value, the longer the pressure support lasts.
