Implanting The Catheter; Activating Or Deactivating The Physiological Alarms; Adjusting Alarm Thresholds - Sophysa PRESSIO 2 Notice D'utilisation

CAUTION
Avoid any contact with the sensor during zeroing
procedure. Calibration in relation to atmospheric
pressure could be falsified.
CAUTION
Keep the sensor immersed in sterile saline solution
during the zeroing procedure. Zeroing the sensor in
conditions other than those recommended may
cause inaccurate pressure readings.
5. While the sensor is immersed, press the Zero button on
the Monitor touch screen
Zeroing the Catheter requires approximately 4 seconds.
Do not move the sensor during the zeroing procedure.
– If the zeroing procedure is successful, the Monitor
touch screen displays a message indicating that the
Catheter is ready to be implanted.
– If the zeroing procedure is not successful, follow the
instructions displayed on the Monitor touch screen.
NOTE
Zeroing the Catheter can only be performed once.
Upon completion, the zero calibration information is
stored in the Catheter dongle. It allows the Catheter to
be disconnected from a Monitor, and re-connected to
any Monitor, without losing the zero calibration informa-
tion.

9.4. IMPLANTING THE CATHETER

Refer to the Instructions for Use of the Catheter kit being
used.
Once the Catheter is implanted, the Monitor displays the
mean ICP value in millimeters of mercury (mmHg).
After the first 24 hours, the Monitor also displays the duration
of the Catheter implantation in the form of the message "Im-
plantation: X days", at the top left corner of the touch
screen, for the entire duration of its implantation.
CAUTION
Catheters are recommended to be implanted for up to
6 days (144 hours). When this duration is exceeded, the
message "Implantation: X days" flashes at the top left
corner of the touch screen and the accuracy of the dis-
played ICP value is no longer guaranteed.
9.5. ACTIVATING OR DEACTIVATING THE PHYSIO-
LOGICAL ALARMS
The Monitor generates two types of visual/audible alarms:
.
– Physiological alarms, to warn the personnel that the mean
ICP and/or the ICT have exceeded the set alarm thresh-
olds.
– Technical alarms, to warn the personnel that there is a
problem with the Monitor or the Catheter.
The specifications for the technical alarms are explained in
Section 17. Technical Specifications (p. 28), at the end of
this document.
To activate or deactivate the physiological alarms:
1. If necessary, first unlock the touch screen by pressing
and holding the button.
2. Press the button.
3. Press "Alarm". The alarm settings screen displays.
4. Select:
– ON to activate the alarms.
– OFF to deactivate the alarms.
5. Press the button to return to the selection menu.
6. Press the button to return to monitoring.
When the ICP and ICT visual and audible alarms are deacti-
vated, this symbol , followed by the note "ALARM OFF"
appears in the status bar:

9.6. ADJUSTING ALARM THRESHOLDS

CAUTION
The alarm thresholds should only be adjusted by a
trained and qualified personnel.
To adjust the alarm thresholds:
1. If necessary, first unlock the touch screen by pressing
and holding the button.
2. Press the button.
3. Press "Alarm". The alarm settings screen displays.
4. Press [-] or [+] to adjust the alarm thresholds.
NOTE
Specifying an alarm threshold in a greyed-out area
is not possible.
5. Press the button to return to the selection menu.
6. Press the button to return to monitoring.
The temperature alarm thresholds can be set between 20 °C
and 45 °C (68 °F and 113 °F), in increments of 0.1 °C or °F.
The pressure alarm thresholds can be set between
-10 mmHg and 40 mmHg, in increments of 1 mmHg.
CAUTION
ICP and ICT alarm thresholds must be set so that phys-
iological alarms can be triggered.
