Power management The anesthesia system can run
on AC power supply and
battery supply, and
1. Battery in Use alarm of
low priority will be
indicated only in case
of AC power supply
failure.
2. The ventilation will be
maintained, and the
control and monitoring
accuracy shall meet the
requirements of the
specification.
3. The fresh gas flow shall
be maintained, and the
accuracy will meet the
requirements of the
specification.
