3 Upon successful completion of the zeroing process, the ICP EXPRESS Monitor will
display the Codman Microsensor's three digit zero reference value. Record the
displayed zero reference value on the Codman Microsensor connector housing
and on the patient's chart for future use
NOTE: When zeroing is complete, the Codman Microsensor's zero reference value
is automatically stored in the memory element embedded in the attached ICP EXPRESS
Cable. By storing the zero reference value in the cable, the user has the ability to move
the patient to a different ICP EXPRESS Monitor without having to manually adjust the
zero reference value on the new unit. This feature can only be utilized if the original
ICP EXPRESS Cable remains with the patient whenever he/she is moved to another
patient monitoring system. If the original cable does not remain with the patient,
the user will be required to manually adjust the zero reference value on the new
ICP EXPRESS Monitor to the zero reference value previously recorded on the Codman
Microsensor connector housing or the patient's chart.
4 If the transducer zeroing process is unsuccessful, the message "TRANSDUCER
ZEROING ERROR" will appear. Verify that the tip of the Codman Microsensor or
ventricular catheter is still laying flat in the sterile water or saline, then press the
key to clear the error and reinitiate the zeroing process. Discontinue use if
the transducer zeroing error persists, and consult with appropriate technical
personnel.
5 After recording the zero reference value on the Codman Microsensor connector
housing and the patient's chart, press the
6 The ICP EXPRESS Monitor is now in standard display mode. The Codman
Microsensor is now ready for placement.
Alarm Functions
Changing Alarm Limits
The HI and LO mean ICP alarm limits have default values of 20 mmHg and 0 mmHg,
respectively. The following instructions describe the correct procedure for changing
these limits.
1 From the standard display mode, press the
screen.
2 Use the
or
keys to move the cursor to the SET ALARM LIMITS line,
key. The HI alarm limit will be displayed above the mean ICP
then press the
value.
3 Use the
keys to increase or decrease the displayed HI alarm limit to
or
the desired value. Press the
displayed above the mean ICP value.
4 Use the
or
keys to increase or decrease the displayed LO alarm limit.
Press the
key to enter the value and return to the standard display mode.
NOTE: The HI and LO alarm limits will reset to their original default values (HI: 20
mmHg; LO: 0 mmHg) whenever the ICP EXPRESS Monitor power is turned OFF
Changing Alarm ON/OFF Status
1 From the standard display mode, press the
2 Use the
or
keys to position the cursor on the TURN ALARM ON or
TURN ALARM OFF line item.
3 Press the
key to enter the new alarm condition and return to the standard
display mode. The new alarm status will be displayed at the top center of the screen.
Manual Functions
The following additional functions are available while ICP monitoring is in progress.
Adjusting the Transducer Zero Reference Value
The following instructions describe the procedure for manually adjusting the zero
reference value for the attached Codman Microsensor. CAUTION: The ICP EXPRESS
Monitor transducer zero reference value setting must only be adjusted manually
if the displayed value differs from the value recorded on the Codman Microsensor
connector housing or patient's chart

4 Use the
or
keys to change the three digit zero reference value until it
matches the value recorded on the Codman Microsensor connector housing or
patient's chart.
5 Press the
key to enter the zero reference value and return to the standard
display mode. The new zero reference value is automatically updated in the internal
memory of the ICP EXPRESS Cable.
Re-Zeroing the Patient Monitor
The following instructions describe the procedure for manually re-zeroing the patient
monitor.
1 From the standard display mode, press the
front panel.
2 Wait for the external patient monitor display to stabilize. If the monitor displays
a value other than 0 mmHg, proceed to zero balance the patient monitor per the
monitor manufacturer's instructions. CAUTION: Discontinue use if the patient
monitor can not be properly zeroed to the ICP EXPRESS Monitor Consult with
appropriate technical personnel
3 Press the
key to resume patient monitoring.
Re-Calibrating the Patient Monitor
The following instructions describe the procedure for manually
re-calibrating the patient monitor.
1 Press the
or the
key on the ICP EXPRESS Monitor panel.
2 If the
is selected, verify that the patient monitor displays exactly 20 mmHg If
key is selected, verify that the patient monitor displays 98 to 102 mmHg
the
There may be a short delay (10–15 seconds) before the patient monitor display
stabilizes. If the patient monitor does not display the correct value, 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

3 Press the
key to resume patient monitoring.
Changing System Components During Monitoring
The following procedures must be followed whenever any component of the original
ICP patient monitoring system (i.e., ICP EXPRESS Monitor, ICP EXPRESS Cable, patient
monitor) is changed or substituted while patient monitoring is in progress.
Switching to a New Patient Monitor
The following instructions describe the procedure for switching the ICP EXPRESS
Monitor to a new patient monitor while patient monitoring is in progress (Example: ICP
EXPRESS Monitor was originally set-up with a patient monitor in the operating room.
Patient is now being moved to the intensive care unit where the ICP EXPRESS Monitor
must be connected to a new patient monitor).
1 Disconnect the Codman Patient Monitor Interface Cable from the original patient
monitor.
2 If the original Patient Monitor Interface Cable is not compatible with the new
patient monitor (i.e., the new patient monitor is of different make and model from
the original patient monitor) disconnect the cable from the rear panel of the ICP
EXPRESS Monitor and replace it with the appropriate compatible cable.
CAUTION: Use Codman Patient Monitor Interface Cables only with the patient
monitor for which they are specifically designed and designated
3 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 new patient
monitor. The sensitivity is preset to the 5 µV position at the time of manufacture.
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 patient monitor, as inaccurate
pressure readings can result
4 Connect the Patient Monitor Interface Cable to the appropriate pressure channel
input on the new patient monitor.
