Low Battery - Integra Codman ICP EXPRESS Manual De Instrucciones

Alarm ON/OFF Status
The Alarm ON/OFF status is displayed in the top center portion of the screen.
When the alarm is ON, the HI and LO alarms will engage whenever the mean ICP
exceeds the HI or falls beneath the LO user programmable limits. When the alarm
is OFF, the HI and LO alarms will not engage, regardless of the mean ICP level.
Alarm Limits
The HI and LO 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 HI and 0 mmHg for LO. Both
limits can be adjusted by using the MENU system.
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,
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
(120/127 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 verifica tion 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
, is displayed in the top left portion of the
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
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 or
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
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 Codman Microsensor must be zeroed at atmospheric pressure, prior
to implantation
CAUTION: The Codman Microsensor transducer tip must remain wet during the
zeroing process
1 Lay approximately three inches of the tip of the Codman Microsensor or ventricular
catheter flat in the marked well of the sterile blister. Pour sufficient sterile water
or saline into the well to just barely cover the Codman Microsensor or ventricular
catheter. CAUTION: Do not submerge the tip of the Codman Microsensor or
ventricular catheter vertically in a cup of sterile water or saline Doing so will
impose pressure on the transducer diaphragm that is higher than atmospheric
zero, resulting in an inaccurate zero reference value
2 While keeping the tip of the Codman Microsensor or ventricular catheter
flat in the sterile water or saline, press the
front panel. The message "TRANSDUCER ZEROING IN PROCESS (PLEASE WAIT)"
will appear on the ICP EXPRESS Monitor screen while the zeroing process takes
place.
