In Volume Control and Pressure Control SIMV, spontaneous
breaths with Pressure Support are available to the patient. In
Volume Target Pressure Control SIMV, spontaneous breaths are
Volume Target Pressure Support breaths.
In SPONT, when Volume or Pressure Control breath type is
selected spontaneous breaths with Pressure Support are
available. In SPONT Volume Target Pressure Control breath type
(Volume Target is selected in Advanced Data Set on GUI), all
spontaneous efforts are assisted by Volume Target Pressure
Support.
Pressure Support
(SIMV and SPONT - Volume Control and Pressure Control breath
types only)
For patient spontaneous efforts that trigger the ventilator, e360
delivers breaths with a constant pressure in the breathing circuit at
a pressure equal to PEEP/CPAP + Pressure Support, until the end
of patient inspiration. The breaths are delivered according to the
user-selected settings for Pressure Support, Slope/Rise,
Expiratory Threshold and PEEP/CPAP. The maximum inspiratory
time is 2 seconds for Adult and 1.2 seconds for Ped/Infant patient
types.
NOTE: When Pressure Support is set to zero (CPAP), the
ventilator raises the pressure in the patient circuit to a target
pressure of 1.5 cmH
2
O/mbar above the set PEEP/CPAP until the
end of inspiration.

arget Pressure Support*
(SIMV and SPONT
- Volume Target Pressure Control breath type
only)
For patient spontaneous breaths in the Volume Target Pressure
Control* SPONT and SIMV modes, the ventilator delivers breaths
with a constant pressure in the breathing circuit at a pressure
equal to a ventilator selected level between PEEP/CPAP + 5
cmH
2
O/mbar and the Pressure Limit, until the end of patient
inspiration.

arget Pressure Support spontaneous breath is
delivered primarily according to the user-selected Tidal Volume
and Pressure Limit and is secondarily affected by PEEP/CPAP,
Slope/Rise and Expiratory Threshold settings. These are very
much like pressure support spontaneous breaths but unlike the
pressure support spontaneous breaths delivered when Pressure
Control or V
olume Control breath type is selected, the pressure
support level is managed breath-by-breath by the ventilator to a
level that is between 5 cmH
