Instructions for Use Fabius MRI SW 3.n 87
Operation
During N
2O failure O2 may still be administered. No
alarm sounds. The float in the N2O measuring tube
drops to zero.
After each O
2 supply failure the O2 shortage alarm
must be reactivated.
However, S-ORC is not an oxygen-specific moni-
toring device and therefore cannot provide any pro-
tection against the effects of accidental use of the
wrong gas.
Therefore always monitor the O
2 concentration.
CAUTION
Risk of inaccurate measuring values
After the O
2 supply has been restored, a supply
pressure of at least 2.7 kPa x 100 must be applied
for at least 20 seconds before another O
2 short-
age signal can be emitted.
During this period, do not activate any devices
that consume O
2 (e.g. O2 flush, O2 fresh gas flow
or secretion aspiration).
WARNING
Damage to materials and health risks
Never switch off fresh-gas flow before the
vaporizer is switched off. A vaporizer must
never be left switched on without a fresh-gas
flow, because high-concentration anesthetic
vapor may leak into machine lines and ambi-
ent air, causing damage to materials and
health risks.
