Setting Up SvO
2
Monitoring
In addition to the Spacelabs Medical module, venous oximetry monitoring requires
an Abbott Oximetrix 3 optical module with connecting cable and an Abbott
Opticath catheter. You must correctly connect all necessary cables, prepare the
catheter and patient for this invasive procedure, and calibrate the catheter to
begin monitoring.
The system provides two calibration methods. The patient’s current status
determines the proper calibration method. You can calibrate the catheter:
• while in its sterile package, or
• after it has been placed within the pulmonary artery, and you can verify
adequate light intensity during monitoring.
Refer to Preparing the Catheter on page 20-5 and Performing Pre-insertion (in
vitro) Calibration on page 20-6 for more details.

monitoring:
1 Place the catheter’s optical
connector into the optical
module on the connecting
cable.
2 Insert the connecting cable into
