2.1 General Operation
1. Turn on the MPM-1 by pressing the
START/STOP button on the front
panel. The MPM-1 will display the
“Camino Logo”(Figure 2-1).
2. Connect the Preamp Cable to the
MPM-1 by inserting the two cable
connectors in the appropriate
receptacle (Figure 2-2). Note the
red alignment marks on the cable
connectors and the side panel.

3. Select the desired Camino Pressure
Monitoring kit. Specific Directions
For Use may be found in the User
information insert provided with
each Pressure Monitoring Kit.
Pressure
Transducer

4. Remove the Catheter from the kit
tray, and firmly connect the
Transducer Connector(s) into the
Preamp Connector(s) (Figure 2-3).
(If a pressure only catheter is used,
then the temperature connector will
remain unconnected). After a short
system test, the MPM-1 Display
will change to the ICP/ICT display
(Figure 2-4).
5. Before inserting the Catheter into
the patient, ensure that the MPM-1
Display indicates an ICP Pressure
of “0 mmHg”. If not, use the tool
from the Catheter Kit to turn the
zero adjustment (Figure 2-5) on the
bottom side of the Transducer
Connector until the ICP Pressure
indicates “0 mmHg”. Also, ensure
that the temperature is a reasonable
value, such as room temperature,
before insertion of the Catheter into
the patient.
6. After the Catheter has been inserted
into the patient, (see the catheter
Directions For Use for proper
insertion technique) select the
appropriate scale by repeatedly
pressing the SCALE button on the
MPM-1 front panel (Figure 2-6).

7. If the MPM-1 is connected to an
external bedside monitor, the
CAL STEP button (Figure 2-7)
may be used to calibrate or
balance the bedside monitor. Each
press advances to the next mmHg
value in the following series: 0,
20, 40, 100, 200 and back to 0.
The CAL STEP momentarily
interrupts normal pressure signal
on both the MPM-1 and on the
external bedside monitor. Press
the CAL STEP button repeatedly
until 0 mmHg is displayed on the
MPM-1. While keeping the button
depressed to maintain 0,
simultaneously zero the bedside
monitor, then release the CAL
STEP button. Within a few
seconds, the MPM-1 will return to
the pressure display. Note that the
CAL STEP button may be used at
any time, and does not affect the
transducer calibration.
8. Press the SYS/DIAS button to
toggle between CPP, ICP, ICT
and SYS, ICP, DIAS displays
(Figure 2-8).

9. Press the TREND button to
display the mean ICP and CPP
value recorded during the
preceding 12 hours (Figure 2-9).
With the next press of the trend
button, the mean ICP and CPP for
the preceding 24 hours will be
displayed (Figure 2-10). Press
again to return to the pressure
display. To clear trend, turn
MPM-1 off momentarily.
NOTE - The trend information will
be lost if the MPM-1 is turned off
or if the battery discharges
completely and the MPM-1 turns
itself off.
NOTE - ICT and CPP values will
ONLY be displayed when using the
appropriate Catheter and/or bedside
monitor input connections.
NOTE - When not in use, the
MPM-1 must be connected to ∼AC
power to maintain battery charge.
TO DISPLAY THE MPM-1
SOFTWARE VERSION
• Make sure that the MPM-1 is
powered off.
• Connect the Pre-Amp cable.

TO CHANGE THE GRAPH MODE
This feature is available on software
version 1.29 and later.
• The graph mode can be either LINE
or FILL (Figure 2-12).
• The initial default graph mode is
FILL.
• The graph mode is saved every time
Directions:
• Make sure the MPM-1 is powered
off.
• Press and hold the SYS/DIAS
button depressed, power on the
MPM-1 by pressing the
START/STOP button.
• Hold the SYS/DIAS button until the
graph screen appears.
• Repeat the above to revert to the
FILL Graph Mode.
TO SET HIGH ICP ALARM
• The initial default ICP ALARM is
set to OFF. After that, the level is
saved every time it is set.
• Reminder: The alarm sounds and
the ICP parameter blinks when ICP
goes higher than the set point.
Directions:
• While the MPM-1 is on, press the
UP or DOWN button, view the
Alarm Select Screen.
• Press the UP button to select the
High ICP ALARM (Figure 2-13).
• Press the UP or DOWN button to
set the ICP ALARM to the desired

TO SET LOW CPP ALARM
This feature is available on software
version 1.31 and later.
• The initial default CPP ALARM
level is OFF. After that, the CPP
ALARM level is saved every time
it is set.
• Reminder: The alarm sounds and
the CPP parameter blinks when
CPP goes lower than the set point.
Directions:
• While the MPM-1 is on. Press the
UP or DOWN button, view the
Alarm Select Screen.
• Press the DOWN button to select
the Low CPP ALARM (Figure 2-
15).
• Press the UP or DOWN button to
set the CPP ALARM to the desired
level.
• Wait approximately 5 seconds for
CPP ALARM to be set.
• Pressing the DOWN button until
the word “OFF” appears disables
this alarm (Figure 2-16).

TO SILENCE THE ALARM
• The initial default CPP ALARM
and ICP ALARM levels are OFF.
After that, the CPP ALARM and
ICP ALARM levels are saved in
memory every time they are set.
Directions:
• Press the SILENCE ALARM
button. The ALARM DISABLED
INDICATOR will flash and
whichever parameter, ICP or CPP,
was in alarm mode will now be
silenced for 3 minutes and that
parameter will flash on the screen
(Figure 2-17).
NOTE: The parameter that is in alarm
mode will blink (even if it has been
silenced). If both alarms were in alarm
mode when the SILENCE ALARM
button was pressed, both alarms will be
silenced. If one parameter (ICP or CPP)
has been silenced and the other
parameter goes into its alarm mode
during the 3 minute silence period, the
silence alarm mode is disabled (the
alarm sounds).
BOTH ALARMS OFF
• As a warning, the ALARM
DISABLED INDICATOR will be
ON (and the alarms will be
disabled) when both of the alarms
have been set to OFF.
