Breathing Pressure Monitoring
Monitor Displays
Information about the patient’s breathing pressure is presented on the
two monitor screens.
• Left-Hand Screen—You can display the breathing pressure
waveform or the breathing rate on this screen.
To display the breathing pressure waveform, press the
TRACE
TRACE key.

– The amount of pressure that the baseline is raised from zero
corresponds to the patient’s positive end expiratory pressure
(PEEP).
– The peak of the waveform corresponds to the peak pressure.
– The slope of the trace as it rises toward the peak pressure is
correlated with the inspiratory flow rate; the steeper the slope,
the higher the flow rate.
– The length of the plateau from peak pressure to the decrease in
pressure corresponding to expiration is equivalent to the length of
the inspiratory pause (if present).
– The horizontal dotted line on the waveform represents the
threshold pressure (apnea) alarm limit. The dotted line appears
only when the trace is scaled for 0–40 cmH

0. The Narkomed 2B
uses this scale when the pressure high alarm limit is set on or
below 60 cmH

0. Adjustment of the pressure high alarm limit is
described later in this section.
To display the breathing rate, press the TREND key
TREND
until the breathing rate graph appears.
