Performing Pre-insertion (in vitro) Calibration To initiate pre-insertion calibration: 1 2 3 4
Touch SVO2. Touch CALIBRATE. Touch PRE-INSERTION. Touch YES.
This calibration procedure tales up to 72 seconds. When calibration is successful, the message PRE-INS CAL COMPLETE displays and the event mark P displays on the oximetry trend. If the catheter fails calibration, verify the following: • • • •
A secure cable connection exists between the optical and SvO2 modules. The catheter tip is inserted properly within the optical connector. You have pressed the optical reference with enough force to hear the click, indicating a secure connection. You tested the catheter by replacing it with a known good catheter to ensure proper catheter function.
Repeated calibration failure with a known good catheter may indicate a defective optical module. Replace the optical module if necessary.
Inserting the Catheter Follow standard hospital procedure to prepare the patient for catheter insertion. 1.
Using sterile procedures, peel back the remaining inner wrap from the catheter tray. Pull the retainer (white tab) to release the catheter.
2.
Grasp the catheter at approximately the 5 cm mark and gently pull it straight out from the optical reference. CAUTION: • The optical fibers can be damaged if you do not draw the catheter out carefully.
3.
Prepare the catheter and insert it into the patient according to hospital procedure. Oxygen saturation readings will immediately display on the bedside monitor.
4.
When the catheter is positioned properly, verify the light intensity signal is within the correct operating range (i.e., the bars on the graph extend at least two vertical dots within the high and low range markers).
5.
Perform a light intensity calibration.

Do not begin a light intensity calibration if the signal is out of range. If this occurs, refer to Correcting Out-of-Range Light Intensity on page 19-10.
Begin continuous mixed venous oxygen saturation monitoring.
