It indicates dynamic pressure in the patient circuit in green, the High

represents the peak pressure of the last breath.
7. To set the parameter settings:
Touch the selection then press the s button to increase the value or
the t button to decrease the value. Then press Accept to confirm the
change. The following parameter choices are available for adjusting:
VT (Tidal Volume) RR (Respiratory Rate)
PEEP PS (Pressure Support)*
Ptrig PC (Pressure Control)
Flow (in volume control)
i time
NOTE: The Flow and i time setting are inversely related to each
other. In Volume Control, the VT (tidal volume) is the controlling
setting. Changing either Flow or i time causes the inversely related
setting to be recalculated to match the new Flow or i time setting and
the VT remains steady.
For example, if you change the Flow rate to a higher setting, the i time
will decrease to meet the new Flow setting. If you change the i time
to a longer time period, the Flow rate will decrease to meet the new i
time setting.
