4 Configuration Settings Appendix
Measurement Settings
Filter This setting lets you apply a 12 Hz or a 40 Hz filter to the pressure signal. Use the 12 Hz filter
when the pressure transducer is connected to the intra-arterial catheter via a fluid filled tubing system
(pressure line). The 12 Hz filter reduces resonant effects that can be introduced by the tubing system. The
40 Hz filter should only be selected when using special pressure transducers, such as catheter-tip pressure
transducers, or transducers that are directly connected to the intra-arterial catheter without the need for a
fluid filled tubing system.
Mercury Cal This setting determines whether the menu entries Cal. Press and Cal.
Factor are shown in the pressure's setup menu. If you want users to be able to perform a mercury
calibration while in monitoring mode, set Mercury Cal to Yes.For detailed information about
performing a mercury calibration, see the monitor Instructions for Use.
Artifact Suppr. Some clinical procedures may affect blood pressure, for example, a flush
procedure or a blood sample. The setting Artifact Suppr.lets you suppress the monitor's normal
response (alarming) to these non-physiological artifacts for a specified duration (30, 60, or 90 seconds, or
Off). During artifact suppression, the monitor shows the INOP message "<Pressure Label>
ARTIFACT", and a question mark is shown beside the pressure numerics. Pressure alarms and the
"<Pressure Label> Non-Pulsatile" INOP are suppressed during the configured period.
Extreme Alarms This setting let you enable or disable the extreme pressure alarms.
Δ Extreme High/Low Extreme High and Low pressure alarms are based on the pressure limit
Δ
Δ
alarms. Use the
Extreme High and
Extreme Low setting to define the difference between the
pressure limit and the corresponding extreme limit. For example, if the High Limit for a pressure is 160
Δ
mmHg and
Extreme High is 15 mmHg, the resulting Extreme High limit is 175 mmHg. Note that
Δ
Δ
the
Extreme High and
Extreme Low settings are the same for all pressure alarm sources:
systolic, diastolic, and mean.
Sys.High/Low Clamp The Sys.High Clamp and Sys.Low Clamp allow you to configure a
safety threshold for the Extreme Low and Extreme High systolic pressure alarms. For example, if the High
Δ
Limit for the systolic pressure is 180 mmHg and the
Extreme High setting is 15 mmHg (180 + 15 =
195) with a Sys. High Clamp set at 190, the resulting extreme high systolic pressure alarm would be
signalled at 190 instead of 195 mmHg. If the clinician sets the high or low systolic pressure alarm limits
above or below the limit clamps, the normal yellow alarm limits become extreme pressure limits and a red
alarm is signalled when the limit is violated. Be sure to set the clamps beyond the configured pressure
limits.
Dia.High/Low Clamp The Dia.High Clamp and Dia.Low Clamp allow you to configure a
safety threshold for the Extreme Low and Extreme High diastolic pressure alarms. For example, if the Low
Δ
Limit for the diastolic pressure is 60 mmHg and the
Extreme Low setting is 15 mmHg (60 - 15 = 45)
with a Dia.Low Clamp set at 50, the resulting extreme low diastolic pressure alarm would be signalled
at 50 instead of 45 mmHg. If the clinician sets the high or low diastolic pressure alarm limits above or
below the limit clamps, the normal yellow alarm limits become extreme pressure limits and a red alarm is
signalled when the limit is violated. Be sure to set the clamps beyond the configured pressure limits.
Mean High/Low Clamp The Mean High Clamp and Mean Low Clamp allow you to
configure a safety threshold for the Extreme Low and Extreme High mean pressure alarms. For example, if
Δ
the High Limit for the mean pressure is 120 mmHg and the
Extreme High setting is 15 mmHg
(120 + 15 = 135) with a Mean High Clamp set at 125, the resulting extreme high mean pressure alarm
would be signalled at 125 instead of 135 mmHg. If the clinician sets the high or low mean pressure alarm
limits above or below the limit clamps, the normal yellow alarm limits become extreme pressure limits and
