B Calibrate the Patient Monitor
1 Press the button ONE TIME to send a 0 mmHg reference
signal to the patient monitor. The green reference LED
marked "0 mmHg" will illuminate and the amber status LED
at the bottom of the front panel will turn off.
Note: If the LED marked "0 mmHg" is not illuminated,
repeatedly press the button until the correct LED is
illuminated.
2 Zero the patient monitor following its manual. Verify
that the 0 mmHg signal is shown on the patient monitor.
CAUTION: If the patient monitor does not display
"0 mmHg" at this point, consider that the patient
monitor may not be compatible
3 Press the button a second time to send a 100 mmHg
reference signal to the patient monitor. The green status
LED marked "100 mmHg" will illuminate. Note: If the
LED marked "100 mmHg" is not illuminated, press the
button until the correct LED is illuminated.
4 Verify that the 100 mmHg signal is shown on the patient
monitor. If the ICP pressure reading on the patient
monitor does not show "100," follow the patient monitor
manual to adjust the monitor gain until it displays "100."
CAUTION: If the reading is significantly different from
100mmHg and if the patient monitor does not allow
adjusting the gain, consider that the patient monitor may
not be compatible
5 Press the button a third time to exit the calibration
mode. The amber status LED at the bottom of the front
panel will illuminate.
6 Proceed to Section C. Zero the ICP Sensor.
Note: Steps 1 through 5 can be repeated at any time for
assurance that the patient monitor is correctly calibrated.
Note: Whenever the amber status LED remains steadily
illuminated, the DirectLink Module sends a signal greater
than 250 mmHg to the patient monitor. Some patient
monitors might display an "over range" pressure message.
C Zero the ICP Sensor
WARNING: The zeroing steps must be performed before the
sensor is implanted Zeroing sensor after it is implanted will
result in incorrect pressure readings
1 Follow sterile technique to open the ICP sensor sterile
package and place the contents on a sterile surface.
2 To attach the ICP sensor to the extension cable and then
connect the cable to the DirectLink module, follow Steps
2 1 through 2 3:
2 1 Pass the connector of the ICP sensor out of the
sterile field and connect it to the ICP sensor
extension cable.
2 2 To connect the other end of the extension cable
to the DirectLink Module, hold the module with
its front panel facing up. Align the extension cable
connector so that the "fin" of the strain relief points
downward. Align the connector to the signal input
receptacle on the module, marked with the symbol
(see Detail "D" of Figure 2).
CAUTION: Align the "fin" of the strain relief of the
extension cable with the receptacle on the module
as outlined in Step 2 2 before pushing these parts
together DO NOT twist the connector after
pushing it in part way Twisting the connector in
this manner will damage the pins and can lead to
product malfunction
2 3 Firmly push the cable connector into the receptacle
until it locks into place.
3 Follow the manual packaged with the sensor. Follow
the technique in the sensor manual to lay the tip of the
sensor horizontally on top of a shallow pool of sterile
water or sterile saline. Press and hold the à0ß button
on the DirectLink Module for until the amber LED
flashes. (This should take approximately 5 seconds.) The
solid green status LED illuminates. This means that the
zeroing process has finished and the zero reference for
that particular sensor has been saved to the DirectLink
Module's memory.
CAUTION: If the solid amber LED turns on again, it means
that the operation to zero the sensor failed because of
one of these conditions:
a The sensor vibrated/was moved/was touched during
the zeroing process
b The sensor is damaged
c The module is damaged and cannot perform zeroing
d The sensor might already be implanted to correct
conditions a through c, repeat Step 3 If it fails
again, use another sensor If it fails yet again, do
not use the module Arrange for replacement of the
DirectLink Module
CAUTION: If the red LED turns on at this stage of
sensor zeroing, see Troubleshooting
4 Verify that the patient monitor displays 0 mmHg. The
sensor is ready to be implanted and must now only
be used with the DirectLink Module with which it was
zeroed. Implant the sensor in the usual manner, in
accordance with its manual. Use the bed clip on the
extension cable to attach any excessive length of the
cable to the bed.
D Implant the Sensor
WARNING: Do not implant a sensor THAT HAS NOT BEEN
ZEROED in accordance with the instructions in Section C
Zero the ICP Sensor Implanting a sensor before it is zeroed
will result in incorrect pressure values being displayed
Read and follow the manual for the sensor to complete the
implantation procedure.
After implantation, follow the instructions in the applicable
section of this manual:
• Resume Monitoring After Temporary Disconnection
(ACKNOWLEDGE Function)
• Connect an Implanted Sensor to a Different Monitor
