
If the entire gas supply (central supply and cylinders) fails, the breathing bag (including the hose
between the breathing bag and the breathing system or the flexible breathing bag arm) must be
removed from the breathing system. The anesthesia device will continue mechanical ventilation
with room air with 21 % FiO2 (volatile anesthetic agent will not be delivered).
4 Very high CO
2
-absorber consumption due to high minute volumes
If possible: Ventilate patients with foreseeable high CO
2
production with an ICU ventilator. Anesthesia
devices should rather be used for patients with expected normal or lower CO
2
production if problems
with the availability of soda lime is expected.

Increase the fresh gas flow to 150% of the minute volume (if necessary, open the emergency
O
2
delivery and add the additional O
2
flow to the system), see Attachment 5: Increasing fresh
gas flow by opening the emergency O2 flow control

If at least 100% of the minute volume is not possible as fresh gas flow (incl. emergency O
2
emergency delivery), remove the breathing bag (including the hose between the breathing bag
and the breathing system or the flexible breathing bag arm)

Do not use volatile anesthetic agents. Without volatile agents you avoid the formation of toxic
substances (e.g. Compound A) when the CO
2
-absorber has dried out. Always use IV medication

With Perseus A500 the FG flow of the electronic gas mixer might be limited at higher respiratory
rates or lower tidal volumes
5 Too much humidity in the breathing system
If possible, ventilate patients with foreseeable high CO2 production with an ICU ventilator.
Anesthesia devices should rather be used for patients with expected lower CO2 production.

Increase the fresh gas flow to 150% of the minute volume (if necessary, open the
emergency O2 delivery and add the add. O2 flow to the system), see Attachment 5:
Increasing fresh gas flow by opening the emergency O2 flow control

Perform intermittent flushing phases from time to time by
o
Manually increasing the fresh gas flow or
o
Keep O
2
flush manually pressed for a longer period of time

Use patient hose systems with water traps, empty water traps regularly (for systems without
water trap, remove water from the hoses regularly)
