Alarm Indicators

HI and LO Mean ICP: The HI and LO alarm limits located in the top right
portion of the screen will flash in reverse video approximately once per
second whenever the mean ICP exceeds the HI or falls beneath the LO
user programmable limits. An audible tone is cycled on and off once per
second when the alarm condition is triggered.
LOW BATTERY: The BAT. LOW message will appear in reverse video at
the bottom center portion of the screen whenever the battery has less than
approximately 15 minutes of life remaining. An audible tone is sounded
once per minute to further alert the user of the low battery condition.
Wrong Key Press: The ICP EXPRESS Monitor will sound a triple audible
tone whenever an incorrect key is pressed.

Alarm SUSPEND

The Alarm SUSPEND symbol,
the screen whenever the SUSPEND key is pressed. In the SUSPEND
mode, the audible portion of the mean ICP alarm is silenced for a two
minute period. The audible alarm will automatically re-activate upon
expiration of the two minute period. The user may choose to manually
re-activate the audible alarm any time prior to the expiration of the
suspend period by pressing the SUSPEND key again.

Operating Instructions

The following instructions describe all necessary steps required to set-up
and operate the ICP EXPRESS Monitor with the CODMAN MicroSensor
ICP Transducer and an external patient monitor. See Figure 4.

Power Up

1. Plug a hospital grade AC power cord into the power entry module located
on the rear panel of the ICP EXPRESS Monitor. NOTE: An optional AC
Power Cord Retainer is provided to prevent inadvertent disconnection of the
AC power supply (refer to the AC Power Cord Retainer section for detailed
installation instructions). Plug the other end of the power cord into a power
supply providing the appropriate voltage (117 VAC for Catalog No. 82-6634;
refer to rear panel label for proper voltage). The front panel AC and
BATTERY CHARGING indicators will illuminate.
2. Press the key to turn the ICP EXPRESS Monitor ON. An audible
tone will sound and the LCD screen will turn dark for a few seconds
permitting verification of the display. The ICP EXPRESS Monitor will
then display the introductory screen.
3. A few seconds will elapse as the ICP EXPRESS Monitor performs a
series of self-diagnostic tests. Upon successful completion of all tests, the
ICP EXPRESS Monitor will display the message, "NO TRANSDUCER
DETECTED (CHECK CONNECTIONS)." This message will be maintained
on the screen until a patient monitor or transducer is connected to the
ICP EXPRESS Monitor. NOTE: If any errors are detected during the self-
test period the ICP EXPRESS Monitor will display an error message.
Discontinue use and consult with appropriate technical personnel.

Connecting the Patient Monitor

1. Verify that the sensitivity selection switch on the rear panel of the
ICP EXPRESS Monitor is set to the correct position, according to
the sensitivity of the patient monitor. The sensitivity is preset to the
5 µV position at the time of manufacture. See the Setting Patient Monitor
Sensitivity section for full details. CAUTION: The rear panel sensitivity
selection switch must be set in the appropriate position prior to
connecting to the patient monitor. Do not adjust the sensitivity
selection switch while connected to a monitor, as inaccurate
pressure readings may result.
2. Plug the appropriate CODMAN Patient Monitor Interface Cable into the
nine pin D-type connector located on the rear panel of the ICP EXPRESS
Monitor. Secure the two locking screws on the cable to prevent inadvertent
disconnection from the ICP EXPRESS Monitor.
3. Plug the other end of the Patient Monitor Interface Cable into the appro-
priate pressure channel input located on the patient monitor. CAUTION:
Use CODMAN Patient Monitor Interface Cables only with the patient
monitors for which they are specifically designed and designated.

Zeroing and Calibrating the Patient Monitor

1. Upon detection of a new patient monitor the ICP EXPRESS Monitor will
automatically prompt the user to zero the patient monitor. The user should
proceed to do so according to the monitor manufacturer's instructions.
2. Once the patient monitor displays 0 mmHg, press the
ICP EXPRESS Monitor to proceed. CAUTION: Discontinue use if the
patient monitor can not be properly zeroed to the ICP EXPRESS
Monitor. Consult with appropriate technical personnel.
3. Next, the ICP EXPRESS Monitor will automatically display instructions
for calibrating the patient monitor. Following the ICP EXPRESS Monitor
prompt, start by pressing the
100 mmHg electronic reference signal to the patient monitor. Use the
20 mmHg calibration reference whenever the patient monitor pressure
display scale is set to less than 100 mmHg (i.e., –10 to 20 mmHg or
0 to 40 mmHg). The 100 mmHg reference is best suited for calibration
when the range is greater than 100 mmHg (i.e., 0 to 120 mmHg).
4. If the key is selected, verify that the patient monitor displays exactly
20 mmHg. If the key is selected, verify that the patient monitor
displays 98 to 102 mmHg. There may be a short delay (10–15 seconds)
while the patient monitor's digital display stabilizes. If the patient monitor
displays a value outside of the specified range, refer to the monitor
manufacturer's instructions for information on how to adjust the pressure
channel calibration or gain (some patient monitors do not have this feature).
CAUTION: Discontinue use if the patient monitor can not be properly
calibrated to the ICP EXPRESS Monitor. Consult with appropriate
technical personnel.
5. Once the patient monitor calibration is complete, press the
to proceed.

Connecting the Transducer

CAUTION: Read all instructions included with the CODMAN
MicroSensor ICP Transducer Kit regarding proper operation prior
to use.
CAUTION: Use only CODMAN MicroSensor ICP Transducers for
intracranial pressure measurements.
CAUTION: Verify ICP EXPRESS Cable integrity prior to use. Do not use
any cable that fails to meet the pin-to-pin resistance or electrical
leakage specifications.
CAUTION: Do not autoclave the ICP EXPRESS Cable. Sterilize the
ICP EXPRESS Cable using ethylene oxide (EtO) gas only.
1. Connect the four pin end of the ICP EXPRESS Cable, Catalog
No. 82-6636, to the white connector on the CODMAN MicroSensor
ICP Transducer.
2. Line up the white indicator marks on the ICP EXPRESS Cable plug and
ICP EXPRESS Monitor front panel receptacle. Guide the plug into the
receptacle until a visible flick of the plug and an accompanying audible
"click" occur. This confirms that the connectors are fully mated and locked.
(NOTE: to release the cable from the ICP EXPRESS Monitor, grasp the
plug near the white indicator arrow and twist one-quarter turn clockwise
while withdrawing.)

Zeroing the Transducer

Upon detection of a new transducer, the ICP EXPRESS Monitor will
automatically display instructions regarding the zero balancing procedure.
CAUTION: The MicroSensor must be zeroed at atmospheric pressure,
prior to implantation.
CAUTION: The MicroSensor transducer tip must remain wet during the
zeroing process.
