3.2.2.2 Preparation of the invasive pressure measurement with micro-chip precision pressure

catheter

•

Please observe the instructions of the catheter manufacturer in the instructions for use for micro-chip

precision pressure catheter!

Prepare the micro-chip precision pressure catheter in keeping with the

instructions of the catheter manufacturer.

•

Connect the ICP-Temp cable to the catheter; connect the connector with the yellow marking to socket

P1, P2 or P3 of the MPR1.

When required, choose another measuring point.

Select the “Zeroing RAUMEDIC Catheter” zeroing option when the RAUMEDIC precision pressure

catheter has been connected!

Please observe the instructions for use of the accessories, such as cable and catheter. If limitations

apply in the permissible measuring range or in the protection against defibrillation, for example, the said

shall have to be adhered to by all means.
