In a similar way to how the anesthetist senses the
restarting of spontaneous breathing in the patient at
the breathing bag and supports it manually, the de-
vice can support insufficient spontaneous breath-
ing.
The device takes over the inspiration work partially,
but the patient, however, retains control of sponta-
neous breathing.
The CPAP system supplies the spontaneously
breathing patient with breathing gas, even with low
inspiration efforts.
When the spontaneous inspiration flow reaches the
set value of the flow trigger, the pressure support
Pressure Support is started. The device then gen-
erates a pressure rise, which can be adjusted for

the patient's breathing requirement, up to the
preselected Psupp
sure increase is adjustable from 0 to 2 seconds.
In the event of a rapid increase in pressure, Zeus IE
supports the insufficient spontaneous respiration of
the patient with high peak flow.
In the case of a slow increase in pressure, Zeus IE
starts gently with an even inspiration flow. The pa-
tient must do more breathing work, and the breath-
ing musculature is trained.
With an adapted pressure rise and Psupp pressure,
the patient determines the required inspiration flow
with breathing activity.

If the inspiration flow decreases to 25 % of the pre-
viously supplied maximum value and no later than
4 seconds (1.5 seconds for pediatric ventilation),
the pressure support Pressure Support is termi-
nated.
If the time criterion takes effect three times consec-
utively, Zeus IE issues a warning and highlights the
possibility of a leaky ventilation system.
The period is defined by the minimum respiratory
rate RRmin after a mechanically triggered, pres-
sure-supported breath is applied. This pressure-
t
supported breath is not initiated by spontaneous
triggering.
Upon cancellation of the Pressure Support cycle,
the device triggers the Apnea ventilation alarm.
Check whether a lower flow trigger is set or there is
a switchover to mandatory breathing.
