Pressure control properties
1. Pressure Control assures that the preset
inspiratory pressure level is maintained
constantly during the entire inspiration.
Breaths are delivered according to the
preset frequency, inspiration time and
inspiratory pressure level resulting in a
decelerating flow.
2. The preset pressure level is controlled by
the system. The resulting volume (shaded
area) depends on the set pressure level,
I:E or Ti, and the patient's lung mechanical
properties.
3. Inspiration starts according to the preset
respiratory rate or when the patient
triggers.
Numbering refers to illustration above.
Expiration criteria
Expiration begins:
• After the termination of preset inspiration
time.
• If the upper pressure limit is exceeded.
• If the delivered tidal volume is twice that of
the set upper limit for tidal volume for the
current patient category.
