• To avoid installation failure, ensure that the proper fiberoptic probe is selected.
• The monitor may only be regarded as a device providing early warning. If there is an indication of a
trend towards de-oxygenation of the patient, blood samples must be taken and tested on a
laboratory oximeter in order to arrive at a decision concerning the condition of the patient.
• Incorrect placement of the fiberoptic probe can lead to vessel perforation. Therefore, check the
correct position of the probe as indicated in the probe’s instructions for use.
