Integra Codman ICP EXPRESS Manual De Instrucciones página 8

EN – ENGLISH
The Codman Microsensor must be zeroed at atmospheric pressure, prior to
implantation.
The Codman Microsensor transducer tip must remain wet during the zeroing process.
Do not submerge the tip of the Codman Microsensor or ventricular catheter vertically
in a cup of sterile water or saline during the zeroing process. Doing so will impose
pressure on the transducer diaphragm that is higher than atmospheric zero, resulting
in an inaccurate zero reference value.
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 the patient's chart.
The mean ICP alarms will reset to default values (LO: 0 mmHg; HI: 20 mmHg)
whenever the ICP EXPRESS Monitor power is turned OFF.
Do not autoclave the ICP EXPRESS Cable. Sterilize the ICP EXPRESS Cable using
Ethylene Oxide (EtO) gas only.
Do not immerse the ICP EXPRESS Cable in any liquid, or allow liquid to enter the plug
or connectors. Do not use cable if connectors become wet. Erratic results can occur.
Always disconnect the ICP EXPRESS Monitor from its power supply before cleaning.
Do not sterilize the ICP EXPRESS Monitor.
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.
The ICP EXPRESS Monitor and external patient monitor pressure displays may be
inaccurate if used simultaneously with radiofrequency electrosurgical equipment.
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.
Discontinue use of any ICP EXPRESS Cable that continues to yield a "-99" transducer zero
reference value (as displayed on the ICP EXPRESS Monitor screen) during manual zeroing or
zero reference verification procedures.
International Symbols
The international symbols on the ICP EXPRESS Monitor are defined as follows:
Refer to instructions for use
ON (CIRCUITS)/STANDBY (CIRCUITS)
Type CF equipment, floating input protected against
defibrillator discharge.
ICP EXPRESS Monitor Description
Front Panel Controls (See Figure 1)
ON/OFF KEY—Turns the ICP EXPRESS Monitor operating system ON and OFF.
NOTE: When ON, the ICP EXPRESS Monitor can be powered either from an
AC power supply or from its internal battery. The ICP EXPRESS Monitor will
automatically switch to battery operation if no AC power is available
0
PATIENT MONITOR ZERO KEY—Initiates an electronic 0 mmHg reference
signal for zeroing an externally connected patient monitor.
PATIENT MONITOR 20 mmHg CALIBRATION KEY—Initiates an electronic
20 mmHg reference signal for calibrating an externally connected patient
monitor.
PATIENT MONITOR 100 mmHg CALIBRATION KEY—Initiates an electronic
100 mmHg reference signal for calibrating an externally connected patient
monitor.
TRANSDUCER ZERO KEY—Zeroes the attached Codman Microsensor
transducer. The zero reference value of the transducer is automatically stored
in the non-volatile memory of the attached ICP EXPRESS Cable.
MENU/ENTER KEY—Accesses the ICP EXPRESS Monitor MENU, or ENTERS a
selected display parameter value such as an alarm limit or a zero reference value.
UP ARROW KEY—Moves the cursor on the MENU screen in the
UP direction, or INCREASES the value of a display parameter such
as an alarm limit or a zero reference value.
DOWN ARROW KEY—Moves the cursor on the MENU screen
in the DOWN direction, or DECREASES the value of a display
parameter such as an alarm limit or a zero reference value.
ALARM SUSPEND KEY—Silences the audible portion of the mean
ICP alarm for a period of approximately two minutes.
Front Panel Indicators
AC Indicator
Lights whenever the ICP EXPRESS Monitor is connected to an AC power supply.
BATTERY Indicator
Lights whenever the ICP EXPRESS Monitor is running only on its own internal
battery power.
BATTERY CHARGING Indicator
Lights whenever the ICP EXPRESS Monitor is connected to an AC power supply
and the internal battery charger is operating. The Battery Charging indicator will
remain lit even when the battery is fully charged.
Front Panel Connector
ICP Input
The ICP EXPRESS Cable connects to this receptacle for direct interface with the
Codman Microsensor ICP Transducer.
Rear Panel Controls (See Figure 2)
Display Backlight ON/OFF Switch
Used to turn the front panel liquid crystal display backlight ON and OFF. When
operating the ICP EXPRESS Monitor on battery the display backlight can be turned
off to conserve power.
Patient Monitor Sensitivity Selection Switch
Used to set the sensitivity of the ICP EXPRESS Monitor external patient monitor
output signal to either 5 µV/V/mmHg or 40 µV/V/mmHg. This switch is preset
to 5 µV/V/mmHg at the time of manufacture. Refer to the patient monitor
manufacturer's instructions to verify the pressure channel sensitivity requirements
of a specific patient monitor.
Rear Panel Connectors
Patient Monitor Interface Connector
Compatible patient monitors can be connected to this receptacle using the
appropriate Codman Patient Monitor Interface Cable. CAUTION: Codman Patient
Monitor Interface Cables must be used only with patient monitors for which they
are specifically designed and designated
AC Power Entry Module
Connects with the AC power cord and provides access to the internal fuses.
WARNING: Do not attempt to bypass the grounding prong on the ICP EXPRESS
Monitor by using a three-prong to two-prong adapter The unit must be properly
grounded to ensure operator and patient safety Grounding reliability can be
achieved only when connected to a receptacle marked "Hospital Only" or
"Hospital Grade "
Pole Clamp
Used for mounting the ICP EXPRESS Monitor to standard pole diameters from
1/2" to 1-1/2" (1.3 to 3.8 cm).
Handle
Used for hand transport.
AC Power Cord Retainer
Used to secure the AC power cord to the ICP EXPRESS Monitor and to prevent
inadvertent disconnection of the AC power cord.
Display (See Figure 3)
Intracranial Pressure
The ICP EXPRESS Monitor 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 and Diastolic ICP values are
displayed with smaller characters in the bottom right portion of the screen.
