Battery Operation; Fuse Replacement - Integra Codman ICP EXPRESS Manual De Instrucciones

5 Follow the instructions for Zeroing and Calibrating the new patient monitor as
previously described in the Operating Instructions section.
Switching to a New ICP EXPRESS Unit
The following instructions describe the procedure for switching the patient to a new
ICP EXPRESS unit while patient monitoring is in progress (i.e., patient was originally
set-up with an ICP EXPRESS unit in the operating room. Patient is now being moved
to the intensive care unit where the original ICP EXPRESS Monitor will be exchanged
with a new unit dedicated to the ICU).
1 Disconnect both the Patient Monitor Interface Cable and the ICP EXPRESS Cable
from the front and rear panel receptacles of the original ICP EXPRESS Monitor.
2 Reconnect both cables to the new ICP EXPRESS Monitor. If the ICP EXPRESS
Monitor is also being connected to a new patient monitor, verify that the Patient
Monitor Interface Cable is appropriate for the new patient monitor.
3 Follow the instructions for Zeroing and Calibrating the patient monitor as previously
described in the Operating Instructions section.
4 The new ICP EXPRESS Monitor will prompt the user to ACCEPT or ADJUST the zero
reference value stored in the attached ICP EXPRESS Cable. Compare the three digit
zero reference value displayed on the screen with the value previously recorded on
the Codman Microsensor connector housing or the patient's chart (the zero
reference values must match if the original ICP EXPRESS Cable has remained with
the patient). If the values do match, position the ICP EXPRESS Monitor screen cursor
on the ACCEPT REFERENCE option and press the
5 If the displayed zero reference value does not match the zero reference value
previously recorded on the Codman Microsensor housing or the patient's
chart, move the ICP EXPRESS Monitor screen cursor to the ADJUST REFERENCE
option and press the key. Use the
displayed zero reference value to match the zero reference value recorded on the
Codman Microsensor housing or the patient's chart, then press the
enter the zero reference value. The new reference is automatically updated in the
ICP EXPRESS Cable memory.
Switching ICP EXPRESS Cables
Integra recommends that the ICP EXPRESS Cable used during the original transducer
zeroing procedure remain with the patient at all times. However, if replacement of the
original cable is necessary, the following procedure must be followed:
1 Unplug the original ICP EXPRESS Cable from the Codman Microsensor and
ICP EXPRESS Monitor. The ICP EXPRESS Monitor will display the message
"NO TRANSDUCER DETECTED (CHECK CONNECTIONS)".
2 Connect the new ICP EXPRESS Cable to the Codman Microsensor and ICP EXPRESS
Monitor. 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
3 If connected to a patient monitor, the ICP EXPRESS Monitor will prompt the user to Zero
and Calibrate the patient monitor as described in the Operating Instructions section.
4 The ICP EXPRESS Monitor will prompt the user to ACCEPT or ADJUST the zero
reference value as read from the newly attached ICP EXPRESS Cable. Since this is a
new ICP EXPRESS Cable, the displayed zero reference value will not match the zero
reference value recorded on the Codman Microsensor housing or the patient's
chart. To adjust the zero reference value, move the cursor to the ADJUST
REFERENCE line and press the
the zero reference value to match the zero reference value recorded on the Codman
Microsensor housing or patient's chart, then press the
reference value and proceed patient monitoring.
Setting Patient Monitor Sensitivity
The ICP EXPRESS Monitor is capable of interfacing with external patient monitors having
invasive piezoresistive pressure transducer sensitivities of 5 µV/Vex/mmHg or 40 µV/Vex/
mmHg. Most patient monitors are designed for a transducer sensitivity of 5 µV, therefore
the sensitivity selection switch on the rear panel of the ICP EXPRESS Monitor is pre-set to
the 5 µV setting at the time of manufacture. To change the monitor output signal to the
40 µV level (in order to interface with a monitor requiring a 40 µV transducer sensitivity),
insert a small flat head screwdriver into the slotted switch and turn one position
clockwise. To change back to the 5 µV setting, insert a small flat head screwdriver and turn
one position counterclockwise. See Figure 5.

Battery Operation

The ICP EXPRESS Monitor is equipped with an internal battery which allows the unit to
operate for approximately three hours under its own power.
The battery is continuously charging whenever the ICP EXPRESS Monitor is connected
to the appropriate AC power supply, even when the operating system is OFF. The
BATTERY CHARGING indicator, located in the lower right corner of the ICP EXPRESS
Monitor front panel, illuminates to verify that the battery is charging. Approximately 12
hours is required to recharge a fully discharged battery. Less time is required to recharge
the battery if it has not been fully discharged. NOTE: The Battery Charging indicator
will remain lit even when the battery is fully charged
The ICP EXPRESS Monitor switches to battery operation during a loss of AC power
without any effect on the operating mode. When less than 15 minutes of battery life
remain, the BAT LOW message is displayed in reverse video in the bottom center portion
of the screen. An audible tone sounds once every minute to further alert the user of the
low battery condition. The user must connect the ICP EXPRESS Monitor to an
appropriate AC power supply as soon as possible once the low battery alert is engaged.
The ICP EXPRESS Monitor will automatically shut down when the battery is fully
discharged. If automatic shutdown occurs while ICP monitoring is in progress, simply
plug the ICP EXPRESS Monitor into an appropriate AC power supply and press the
key to turn the unit back on. The ICP EXPRESS Monitor will prompt the user to zero and
calibrate the patient monitor, and to verify the transducer offset of the attached Codman
Microsensor. NOTE: The HI and LO mean ICP alarms will reset to the default values (HI:
20 mmHg; LO: 0 mmHg) after a battery discharge shut down The ICP EXPRESS Monitor
must remain connected to the AC power supply for at least 12 hours to fully recharge
the battery.
IMPOR TANT BATTERY MAIN TE NANCE INFOR MA TION!
To main tain the ICP EXPRESS Monitor recharge able battery in optimum con di tion:
1 Charge for at least 12 hours within seven days of a com plete dis charge.
key to
2 Charge for at least 12 hours once every six months when unit is not in regular use.
Charging occurs auto mat i cally when ever the unit is con nected to AC power. Failure to
main tain the battery as described can result in reduced battery life.

Fuse Replacement

1 Turn the ICP EXPRESS Monitor OFF and remove the power cord from the rear panel
AC power entry module. WARNING: Disconnect the ICP EXPRESS Monitor from all
external AC power sources before changing fuses
2 To remove the fuse holder, place a small screwdriver, or fine pointed object, in the
slot at either side of the panel and gently press the tab so that the holder pops
partially out. Pull the fuse holder straight out to expose the fuses. See Figure 6.
3 Remove the fuses by pulling them straight out of the fuse holder.
4 Replace the fuses with the same type and rating as indicated on the rear panel
label. For model 82-6634 use 5 x 20 mm, 0.25 A, 250 V, time delay (SB or T) type
fuses.
5 Replace the fuse holder by inserting it into the receptacle and pushing firmly until
the fuse holder pops back into place on both sides. The fuse holder is keyed to
prevent improper installation.
NOTE: If the fuses continue to blow, contact appropriate technical personnel
AC Power Cord Retainer
A removable AC power cord retainer is included for optional use. When properly
installed, the retainer will prevent inadvertent disconnection of the AC power cord.
WARNING: Disconnect the AC power cord from the AC power supply before
installing or removing the AC power cord retainer
1 Use a Phillips screwdriver to remove the screw located directly underneath the AC
power entry module on the rear panel of the ICP EXPRESS Monitor (refer to Figure
7-1). DO NOT discard the screw; it will be reinstalled in Step 4.
2 Plug the AC power cord into the power entry module as shown in Figure 7-2.
3 Place the "U" shaped arm of the retainer around the shoulder of the power cord
plug, as shown in Figure 7-3. Align the hole in the retainer with the screw hole
located directly beneath the AC power entry module.
