Mechanically controlled gas mixer:
WARNING
Risk of incorrect gas delivery
Use the flow values on the status display as
the primary source of information. Always
compare these values with the values on the
total flow tube.
Only use the total flow tube as the primary
source of information in the following cases:
– The status display has failed.
– The values on the status display do not
match the values on the total flow tube.
 Use the flow control valves to adjust the
fresh-gas flows.
Use the total flow tube to check the total
flow set, see page 32.
CAUTION
Risk of patient injury
Unsuitable soda lime can result in disintegration
products from the anesthesia gases.
Use suitable soda lime such as Drägersorb Free.
WARNING
Risk of patient injury
Under certain conditions, acetone can
accumulate in the body in patients under
anesthesia. As a result, the patient could be
put at risk.
Do not perform low-flow anesthesia on
patients with ketoacidosis or patients under
the influence of alcohol.
CAUTION
Risk of patient injury
The use of minimum-flow or low-flow settings can
lead to accumulation of metabolic by-products in
the breathing system.
When using minimum-flow setings or low-flow
settings follow the recommendations of
professional societies (e.g., regular flushing of
the breathing system).
