SIMV with Pressure Support
Any breath the infant initiates beyond that which the ventilator is
programmed to deliver will be supported with a given amount of pressure
above PEEP but still less than PIP.
AC:ASSIST CONTROL
All patient breathing efforts result in a machine delivered breath. These
modes (pressure control, volume control) do not compensate for the
changes in pulmonary mechanics and are unable to deliver consistent
tidal volume.
(N)CPAP:(NASAL) CONTINUOUS POSITIVE AIRWAY PRESSURE
This is simply PEEP. The infant breaths around a continuous flow of
positive pressure. Helps to boost functional residual capacity (FRC) in
neonates by stenting open otherwise floppy airways. Can be delivered
either through ETT (CPAP) or through nasal prongs (NCPAP) or through
a specialized cannula (RAM). If you are delivering NCPAP or RAM using
some ventilators, you can add a rate, but one must also set a PIP for
those breaths (often called nasal ventilation).
PRVC:PRESSURE REGULATED VOLUME CONTROL/PRESSURE
GUARANTEED VOLUME CONTROL
Best of both worlds! Allows one to ventilate with volume, but within
pressure limits that are pre-set. Operator sets VT,PEEP, I-time, and rate,
