Explanation of Modes, Breath Types and Special Functions
spontaneous breaths in the Volume Targeted 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cmH2O/mbar
and the pressure limit, until the end of patient inspiration which
is determined by the attainment of one of the three cycling off
thresholds.
Each VTPS spontaneous breath is delivered according to the
user-selected Tidal Volume and Pressure Limit, Slope/Rise and
PEEP/CPAP settings. These are very much like pressure support
spontaneous breaths but unlike the pressure support spontaneous
breathsdeliveredwhenPressureControl,BPRVorVolumeControl
breath type are selected, the pressure support level is managed
breath-by-breath by the ventilator the lowest level possible between
5cmH2O/mbar above PEEP/CPAP and the Pressure Limit setting in
order to try to achieve the set tidal volume. The set tidal volume is not
guaranteed for each breath, it is a target.
The target pressure of the first breath, when no target pressure has
beenestablishedisPEEP/CPAP+5cmH2O/mbar.
Volume Target Pressure Support (VTPS) breaths are cycled off based
onattainingoneofthreethresholds:apercent(%)ofpeakow
(user set via Expiratory Threshold in Advanced Data Set), maximum
inspiratory time (2.0 seconds for Adult, 1.2 seconds for Ped/Infant)
or pressure overshoot, whichever comes first. See Figure 7-2 for an
illustration of the pressure overshoot cycling off function.
