Inserting the Catheter

Place the optical connector into the optical module (with the label “TOP” facing upwards) and 
close the lid.

In the 

menu, select 

. Ensure that the tip of the catheter is still 

in the optical reference.

Insert the catheter when you see the message

. If the calibration fails, repeat the calibration before inserting the 

catheter. If it fails a second time, replace the optical module.

Remove the inner cover of the catheter tray.

Remove the catheter tip from the optical reference. Check the catheter's proper operation (for 
example: the balloon tip).

Prepare and insert the catheter in accordance with standard hospital practice.

 catheter is thin and flexible, treat it carefully. Avoid kinking, bending or grasping the 

catheter with forceps or a hemostat. Damage to the fiber results in low intensity light and sudden 
decrease in intensity readings. Refer to the documentation provided with the fibre-optic catheter, 
paying special attention to any precautions, warnings or contraindications.

Secure the optical module directly or in close proximity to the patient, to avoid placing excessive 
tension on the catheter, which would result in movement of the catheter tip from the optimal position 
in the patient. Position the optical module to avoid contact with liquids, because fluid entering the 
catheter-optical module connection may impair light transmission.

If you place the catheter in the patient without performing the pre-insertion calibration, you must 
perform an in-vivo calibration once the catheter is in place.

Perform a light intensity calibration after the catheter is in its proper position. When the catheter is 
positioned properly, the light intensity indicator must cover at least two small divisions above the 
midpoint.

In the 

menu, select 

.

Calibration is complete after a few seconds. If you doubt existing light intensity readings, recalibrate.
