halogenated agents. The
measured MAC is less
than 3.
Mixed Agent Med
The AG module detects
two and more types of
halogenated agents. It
cannot detect the
specific MAC value
(invalid value).
1. Check whether only one type of
halogenated agent is used.
2. If only one type of anesthetic agent is
used, set the fresh gas flow to 6L/min or
above, and check 20s later.
3. If the problem persists, replace the AG
module.
Mixed Agent and
MAC ≥ 3
Med
The AG module detects
two and more types of
halogenated agents. The
measured MAC is
greater than or equal to
3.
1. Check whether only one type of
halogenated agent is used.
2. If only one type of anesthetic agent is
used, set the fresh gas flow to 6L/min or
above, and check 20s later.
3. If the problem persists, replace the AG
module.
CO2 Overrange Low
The monitored value
exceeds the
measurement range of
the module.
1. Decrease the concentration of the
monitored gas to the normal range.
2. If the problem persists, calibrate the
AG module again.
3. If the problem persists, replace the AG
module.
O2 Overrange Low
The monitored value
exceeds the
measurement range of
the module.
1. Decrease the concentration of the
monitored gas to the normal range.
2. If the problem persists, calibrate the
AG module again.
3. If the problem persists, replace the AG
module.
N2O Overrange Low
The monitored value
exceeds the
measurement range of
the module.
1. Decrease the concentration of the
monitored gas to the normal range.
2. If the problem persists, calibrate the
AG module again.
3. If the problem persists, replace the AG
module.
N2O Overrange Low
The monitored value
exceeds the
measurement range of
the module.
1. Decrease the concentration of the
monitored gas to the normal range.
2. If the problem persists, calibrate the
AG module again.
3. If the problem persists, replace the AG
module.
Hal Overrange Low
The monitored value
exceeds the
measurement range of
the module.
1. Decrease the concentration of the
monitored gas to the normal range.
2. If the problem persists, calibrate the
AG module again.
3. Replace the AG module.
Enf Overrange Low
The monitored value
exceeds the
measurement range of
the module.
1. Decrease the concentration of the
