9.7. CONNECTING AND CALIBRATING THE PATIENT
BEDSIDE MONITOR
WARNING
Only connect the Monitor to patient bedside monitors
which are compliant with IEC 60601-1, and marked
"BF" or "CF" or bearing the international symbols:
Once the Catheter is implanted, and the first measurements
have been displayed on the Monitor, connecting the Monitor
to the patient bedside monitor allows the ICP and ICT values
to be displayed along with other physiological parameters on
the patient bedside monitor.
NOTE
If the patient bedside monitor has not been calibrated,
the Monitor sends a warning value of 360 mmHg to the
patient bedside monitor. The patient bedside monitor
may then display the value "360" or another pressure
over range message.
1. Connect the Monitor to the patient bedside monitor us-
ing the pressure cable (PSO-MCxx) and temperature ca-
ble (PSO-MCT-y) specific to the patient bedside monitor.
CAUTION
Check the proper connection of the pressure cable
carefully before the patient bedside monitor cali-
bration procedure.
The Monitor automatically detects the connection to the
patient bedside monitor and displays the following mes-
sage: Sending 0 mmHg signal to patient monitor.
2. On the patient bedside monitor, press the zero (0) key
relating to the ICP parameter (refer to the documentation
for the patient bedside monitor being used).
3. Check that the patient bedside monitor displays
0 mmHg, then return to the Monitor touch screen and
. The following message displays: Sending
press
30 mmHg signal to patient monitor.
WARNING
During the sending of the 30 mmHg signal, do not
press the zero (0) key on the patient bedside moni-
tor.
4. On the patient bedside monitor, wait until the measure-
ment stabilizes (approximately 30 seconds) and check
that the value displayed is 30 mmHg.

NOTE
Because of the calculation methods and rounding,
the patient bedside monitor can display a value
which is different than the value displayed on the
Monitor. For the 30 mmHg calibration, displayed
values between 29-31 on the patient bedside moni-
tor are acceptable.
If the values displayed on the patient bedside mon-
itor are outside of this range, two solutions are pos-
sible:
– adjust the patient bedside monitor gain so that it
displays the desired value,
– read the difference in values and take it into ac-
count when adjusting the alarm thresholds on
the patient bedside monitor.
5. If the patient bedside monitor displays 29, 30 or
31 mmHg, return to the Monitor touch screen and press
.
The following message displays: Sending 60 mmHg
signal to patient monitor.
WARNING
During the sending of the 60 mmHg signal, do not
press the zero (0) key on the patient bedside moni-
tor.
6. On the patient bedside monitor, wait until the measure-
ment stabilizes (approximately 30 seconds) and check
that the value displayed is 60 mmHg.
For the 60 mmHg calibration, displayed values between
58-62 on the patient monitor are acceptable. Outside
these values, apply one of the two solutions described
previously in the Note in step 4.
7. When the patient bedside monitor displays values be-
tween 58 and 62 mmHg, return to the Monitor touch
screen and press
9.7.1. Repetition of the Patient Bedside Monitor Calibra-
tion Procedure
The patient bedside monitor calibration procedure may be
repeated, if necessary, in the following situations:
– Powering off of the Monitor or the patient bedside monitor.
– Disconnection of the pressure cable between the Monitor
and the patient bedside monitor.

9.7.2. Alarm Thresholds

The alarm thresholds selected within the Monitor are not ac-
quired by the patient bedside monitor. They must be set di-
rectly on the patient bedside monitor.
9.7.3. Temperature
The ICT measurement is detected by the patient bedside
monitor as soon as the temperature cable is connected. It
does not need calibration.

9.8. CHANGING THE MONITOR

The Catheter zeroing information is stored in the Catheter
dongle. Once the Catheter is implanted, it can be disconnec-
ted from and then reconnected to the same Monitor, or re-
to return to monitoring.
