inadvertent disconnection of the AC power cord.
Display (See Figure 3)
Intracranial Pressure
The ICP EXPRESS Monitor display contains the digital values of the Mean, Systolic
and Diastolic ICP in units of millimeters of mercury (mmHg). The Mean ICP is the
large value displayed in the center of the screen. The Systolic (SYS) and Diastolic
(DIAS) ICP values are displayed with smaller characters in the bottom right portion
of the screen.
Alarm ON/OFF Status
The Alarm ON/OFF status (
) is displayed in the top center portion of the
screen. When the alarm is ON (
engage whenever the mean ICP exceeds the HIGH ( ) or falls beneath the LOW
( ) user programmable limits. When the alarm is OFF, the HIGH ( ) and LOW ( )
alarms will not engage, regardless of the mean ICP level.
Alarm Limits
The HIGH ( ) and LOW ( ) limits for the mean ICP alarm are displayed in the top
right portion of the screen. The default values for these limits are 20 mmHg for
HIGH ( ) and 0 mmHg for LOW ( ). Both limits can be adjusted by using the
MENU system.
Alarm Indicators
HIGH ( ) and LOW ( ) Mean ICP: The HIGH ( ) and LOW ( ) 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 HIGH ( ) or
falls beneath the LOW ( ) user programmable limits. An audible tone is cycled on
and off once per second when the alarm condition is triggered.
LOW BATTERY: The LOW BATTERY icon,
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 when-
ever an incorrect key is pressed.
Alarm SUSPEND
The Alarm SUSPEND icon,
, is displayed in the top left portion of 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 can
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 (230
VAC nominal for catalog no. 82-6635; refer to rear panel label for proper voltage). The
front panel AC (
) and BATTERY CHARGING (
), the HIGH ( ) and LOW ( ) alarms will
, will appear at the bottom center
) 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 can 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 appropriate
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 must proceed
to do so according to the monitor manufacturer's instructions.
2 Once the patient monitor displays 0 mmHg, press the
Monitor to proceed. CAUTION: Discontinue use if the patient monitor cannot 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
or
key to send a 20 mmHg or 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 can 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 cannot be properly calibrated to the ICP
EXPRESS Monitor Consult with appropriate technical personnel
5 Once the patient monitor calibration is complete, press the
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 (EO) gas only
