Operating Instructions
Real Time Pressure Bar Graph
A common feature of all data screens is the real time pressure bar graph.
The bar graph represents the instantaneous pressure within the breathing
circuit. If the pressure exceeds the limits of the display (more than 120 cm
H
2
O or less than -10 cm H
2
O), the bottom or top segments will blink. The
unit displays two stationary segments; one that corresponds to the high
pressure alarm limit, and the other that corresponds to the low pressure
limit.
Breathing Pressure Low Limit
The breathing pressure low limit setting serves two purposes. First, when
the peak breathing pressure stays below the low limit for fifteen (15)
seconds, the Pressure and Respiratory Rate displays will display dashes
(---). Second, when the PEEP pressure stays above the low limit for fifteen
(15) seconds, the continuous pressure alarm is annunciated.
User Input Keys
User input keys are grouped into three categories: display function keys,
alarm function keys, and calibration function keys. See
Figure 3-1.
