Correcting Insufficient Light Intensity
The message INSUFFICIENT LIGHT displays when an unusually small amount of
light is being received during monitoring or during pre-insertion calibration.
Take the following actions:
• If this message displays while the catheter is exposed to room light during
pre-insertion calibration, take no action. It disappears when the catheter is
placed in the patient.
• If this message displays during pre-insertion calibration while the catheter is
connected to the optical module, verify proper connection to the module.
• Check that the tip is fully inserted into the optical reference and firmly press
PUSH on the optical reference until you hear a click. Do not use the catheter
if the tip is pulled out of the optical reference when you receive the catheter
tray.
• Disconnect the optical module from the catheter, close the optical module lid,
and place the optical module in an area out of direct light. If the message
disappears, replace the catheter. If the message remains, contact your
system administrator.
• Examine the catheter for kinking. If optical fibers are damaged, replace the
catheter.
Correcting Calibration Errors
The message CALIBRATION REJECTED displays when pre-insertion or in vivo
calibration is not successful.
Take the following action as indicated:
• Check for secure catheter connection to the optical module. Reconnect the
catheter if necessary.
• Check the status message on the monitor screen to verify sufficient, stable
light intensity. If the INSUFFICIENT LIGHT message displays, refer to the
previous section which describes steps to correct this condition.
• Allow the optical module to warm up for one more minute, then retry.
The message NOT CALIBRATED displays and an alert sounds (if alarms are ON)
if you begin monitoring before you calibrate the system. The message disappears
after you complete a successful calibration.
Correcting Optical Module Errors
The SvO
2
module performs constant memory checks to ensure data is not lost or
changed erroneously. When the OPTICAL MODULE MEMORY ERROR
message displays, replace the optical module with a known good unit.
Expect the NO OPTICAL MODULE message whenever you disconnect the
optical module from the Sv
O
2
module because this suspends SvO
2
monitoring.
If this message appears when the optical module is not disconnected, replace the
module or contact a qualified service person.
