● Multi Gas
If any problem occurs in CO2 or anesthesia gas measurement, the adapter is the first thing that
you should check. If after replacing adapter the problem is not resolved, contact the
manufacturer. You can perform zeroing procedure according to instructions of this manual to
obtain an accurate reading.
● BFA
If any problem occurs in BFA monitoring, the most important item that you should check is
proper attachment of neuro sensors. Please clean the skin before attaching the sensor or use a
new sensor, if necessary. If the problem is not resolved, contact after sale service.
●
BFA module does not turn on when it is connected to the monitor.
- Check interface cable between the module and the monitor.
- If the problem persists, contact after sale service of manufacturer
●
BFI is higher than expected range
- Check anesthetic delivery systems: IV lines and status of vaporizers.
- Some patients require more doses of drug to reach intended level of anesthesia.
- Drug dosage is not sufficient for Maintenance phase, so BFI increases during painful
stimulations.
●
BFI rises along with EMG
High levels of facial muscular or electromyographic (EMG) activity can elevate the BFI
under certain circumstances. When this happens, attention must be paid to reactions of
patient against the stimuli during surgery. When the patient is asleep, EMG activity may
increase due to reactions to painful stimuli during surgery, lack of muscular relaxation or
muscular rigidity caused by some opioids (analgesics). In the presence of hypnotically
unrelated EMG, administration of a neuromuscular blocking agent may decrease BFI.
