2.1.1 MAP (Mean Arterial Pressure)
Mean Arterial Pressure is calculated from the systolic and diastolic measurements. MAP may be
optionally displayed by selecting it on the Advanced Configuration menu. MAP is displayed in the upper
left corner of the screen.
MAP - (Mean Arterial Pressure) display can be
turned on and off by using the Advanced
Configuration menu. When MAP is shown, you
will see it in the upper left corner of the screen,
above the ECG waveform.
To display (or turn off) MAP, enter the Advanced
Configuration menu:
• Press the Date/Time button.
• Press the Trend button.
• Use the left Select button to highlight
“MAP.”
• Press the left Set to choose “Yes” or “No.”
• Press the Trend button again to exit
Advanced Configuration.
If MAP is displayed on the screen, it will also
appear in the trend data and in the current
readings of a waveform printout.
Alarms - When either of the MAP limits are
exceeded, an audible alarm sounds and the
affected measurement flashes. If the Print On
Alarm configuration is set to Yes, a MAP alarm
will trigger an automatic print. You can silence
the MAP alarm, and all alarms, by pressing the
large blue
Silence button at the right side of the
instrument. This will silence all alarms for 60, 90,
or 120 seconds, depending on the setting selected
in Advanced Configuration. However, any
measurement still outside the set limits will flash.
When alarms are silenced, they do not trigger a
Print On Alarm.
To suspend the MAP alarm, press the
BP
ALARMS Off button so the red LED in the button
lights. A suspended alarm will still flash if it goes
outside the range of the limits, but it will not
sound the audible alarm. When an alarm is
suspended, it will not trigger a Print On Alarm.
Note: The BP alarm can be suspended for only 3
minutes when the language setting is
configured to “Francais”. If the language is set
to any other language, pressing the
BP
ALARMS Off button will suspend the alarm
until you remove the suspension.
Note: MAP is calculated mathematically from the
Systolic and Diastolic pressures; it is not
measured directly.
Setting alarm limits – If MAP is displayed, you
can set the alarm limits, using the
Select and Set
buttons on the left side of the monitor to follow
these steps:
• Press the left Select button to cycle
through MAP HI and LO , Heart Rate HI and
LO , Respiration HI and LO (models 622xx
or 623xx) , then (model 623xx) CO
2
HI and
LO .
• Each push of Select moves you to the next
limit. Stop at the limit you want to set. The
measurement and
HI or LO will flash,
indicating which limit is being changed.
• Press the Set button up or down to raise or
lower the alarm limit. (When you come to
the end of the range, the numbers will stop
changing).
• Press the Select button again to go to the
next limit, or press it several times until
none of the measurements flash and no
HI
or LO indicators are lit. The instrument is
now in its normal measurement mode. (If
you do not press any button for 10 seconds,
the instrument will automatically revert to
its normal measurement mode).
