Preparing to Monitor SvO

In addition to an SvO
2
module, you need a Hospira OptiCath catheter, and 50131 Optical Module.
Use only the Hospira accessories listed in the Accessories section.
Connect the optical module (Hospira 50131) to the Sv
O
2
module. Allow the optical module to warm
up before you perform a calibration. Although the warm up message disappears from the screen after
one minute, Hospira recommends letting the optical module warm up for 15 minutes for best
accuracy. Please refer to the instructions for the optical module.
To avoid false alarms during the pre-insertion calibration and insertion of the catheter into the patient,
the monitor automatically suspends alarms during the pre-insertion calibration, for up to three minutes
after you remove the catheter tip from the optical reference. After light intensity calibration, or after
three minutes (whichever comes first), the monitor returns to the alarm state it was in prior to pre-
insertion calibration.
Carrying out a Pre-insertion Calibration
WARNING It is strongly recommended to carry out a pre-insertion calibration prior to all insertions. If this is not
possible, you must perform an in-vivo calibration after insertion.
Refer to the instructions for use that accompany the catheter. Do not use the catheter if the packaging
is damaged. If you have to disconnect the monitor from the patient (for example, when transferring the
patient from one location to another), you must disconnect at the Sv
O
2
module. The catheter should
remain in the optical module, otherwise you need to recalibrate.
1 Remove outer wrapping from catheter tray to uncover optical connector.
2 Place the optical module on the catheter tray in the space provided and open the lid.
