Monitoring Invasive Pressures

Option Function
SCALES Select the size of displayed waveforms. The higher the scale
value, the smaller the waveform scale.
„
AUTO — Adjusts the scale to patient’s ART pressure,
Auto scaled waveforms print at a slightly different scale
than the display scale.
„
FULL — Allows you to select the scale size and
position on the display; right ( R ) or left ( L ).
CURSOR Display a horizontal line with a numeric value over the
waveform to indicate a pressure value at specific position on
the waveform.
CLEAR CURSOR Remove the cursor from the waveform.
LIMITS Select the high and low alarm limits for heart rate, systolic,
diastolic and mean pressures. An alarm sounds when a
value occurs outside of these limits.
NOTE
Adjusting the HR limits affects the pressure tracing, not
the primary ECG HR alarm level.
CHANGE NAME Select the site name for the monitored pressure site for
accurate waveform processing (for example, if monitoring
the femoral pressure site, select
FEM ).
ZERO Zero a single transducer. To zero all transducers, press the
Zero All key.
BP FILTER Select one of the following filter options:
„
12 HZ — Recommended for typical monitoring.
„
40 HZ — Recommended for higher frequency
waveform component processing. May result is
elevated pressure values.
CALIBRATE
TRANSDUCER Adjust the monitor to compensate for transducer errors.
Measurement errors can be identified when pressure
calibration is measured with other instruments (for example,
a manometer).
„
CAL# 100 — Select the percentage of error when the
calibration error is known; (for example, 102 if the
transducer measured two percent high).
„
ADJUST TO MMHG — Select the millimeters of
mercury.
SPEED Select a sweep speed for the displayed waveform. The
smaller the speed value, the slower the speed (greater
number of complexes).
