In this case, make sure that the catheter connector is pushed right up to the stop
in the catheter extension cable, and that the latter is correctly connected to the
Pressio® monitor.
3) Preparation of the sterile water cup
Prepare a sterile saline solution (or even sterile water) and a cup in a sterile environment.
Pour the sterile saline solution (or sterile water) into the cup.

4) Zeroing the catheter
Immerse the sensor (metal part) in the liquid completely.
Be careful not to touch the cup with the sensor.
When the sensor is ready, press the zeroing key

INACCURATE PRESSURE READINGS
Movement of a task progress bar makes it possible to follow the correct performance
of the zeroing.
The procedure takes about 4 seconds.
5) Verifi cation that the zeroing procedure took place correctly
When the progress bar reaches the end, the message "ZERO SENSOR OK – INSERT
SENSOR" shows that the procedure has taken place correctly.
Check that the Pressio® monitor screen displays the value "0 mmHg" (or the patient
monitor screen if the Pressio® interface is used).
If during zeroing, the sensor suff ers parasite pressure variations or is damaged,
the screen will display the message "ZERO SENSOR FAILURE – REPLACE SENSOR".
In this case, disconnect and then reconnect the catheter, and try the zeroing
sequence again.
If this fails again, change the catheter.
Also refer to the instructions for use for the Pressio® monitoring system used
(PSO-3000 or PSO-IN00, § "Anomaly in operation: symptoms / suggested measures").

THE MESSAGE
Storing data in the catheter connector memory (cf. §3) makes it possible to use
Pressio® monitors or interfaces (PSO-3000 models software V2, PSO-3000
software V1 and PSO-IN00) other than the model on which the zeroing was
performed.
