A spacer ring [8] mounted on the bolt makes it possible to adjust the seating depth
for the bolt depending on the thickness of the skull bone of the patient.
The guide stylet [9] is inserted into the bolt [4] (nut [6] unscrewed). It makes it
possible to create a passage through the parenchyma to facilitate the introduction
of the Pressio® catheter.
It is delivered inserted into the bolt.

Configurations for Pressio® parenchymal kits
with bolt
The Pressio® parenchymal kits with bolt come in two different models: PSO-PB and
PSO-PBT (cf. §3: " Description and Operating principle for Pressio® parenchymal kits
with bolt ").
In both cases the specific accessories for the introduction of the catheter into
the parenchyma and its fixation using a bolt are included in the kit, ready-to-use.
Sophysa also offers a sterile disposable hand drill (PSO-DR), enabling the skull
to be perforated in combination with the drill bit supplied in each kit.
Pressio® catheters are used with one of the Pressio® monitoring systems and the
appropriate accessories (cf. PSO-3000, PSO-IN00, and PSO-MT00 instructions for use).
Specific case for the PSO-PBT:
To make the best use of an intracranial temperature and pressure catheter, a Pressio®
monitor, Model PSO-3000 Software Version V2, must be used.

Units of measurement
Catheter diameters (D)
D(mm) = Fr / 3
Fr = D(mm) x 3
Intracranial pressure
The pressures mentioned are in mmHg.
1 mmHg corresponds to 13.60 mmH
Intracranial temperature
The intracranial temperature can be displayed in degrees Celsius (°C) or degrees
Fahrenheit (°F).
°F = °C x (9/5) + 32
°C= (°F - 32) x (5/9)

Sterilization of Pressio® kits
The Pressio® monitoring kits are packed individually in double peel-off, sterile,
pyrogen-free packaging. They are sterilized with ethylene oxide.

Instructions
Before any implantation, it is recommended that the instructions for use
of the Pressio® monitoring system used be consulted for installing and
setting it up (Pressio® monitor or interface).
Preparation of a Pressio® catheter BEFORE IMPLANTATION:
zeroing the pressure sensor
Before implanting the Pressio® catheter it is necessary to zero the pressure sensor
(calibration in relation to atmospheric pressure).
The intracranial temperature sensor is factory calibrated. Therefore the temperature
setting does not need prior zeroing.
:
Ensure that the asepsis of the Pressio® monitoring kit is maintained throughout
this step.
1) Powering up the monitoring system
monitor
Connect the catheter extension cable (PSO-EC20) to the Pressio® monitoring system.
Before opening the packaging which guarantees the sterility of the Pressio®
monitoring kit, turn on the Pressio® monitoring system (PSO-3000 or PSO-IN00).
Refer to the instructions for use of the Pressio® Monitor or Interface.
2) Connecting the catheter to the monitoring system
Make the connection between the catheter and the extension cable (PSO-EC20)
respecting the guide pin.
Align the blue arrow on the catheter connector and the blue arrow on the cable
connector: the catheter connector will be guided safely into the cable connector.
Push up to the stop to ensure that the connection is complete.
