Useful Tips - Dräger Perseus A500 Instructions For Use Manual

Operation
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 against the values on
the total flow tube.
Only use the total flow tube as the primary
source of information in the following
circumstances:
– 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 28.
Perseus is equipped with a minimum O
which ensures that a minimum quantity of oxygen
is delivered when N O is used as the carrier gas,

see page 247. To prevent the soda lime from
drying out at an increased rate, the electronically
controlled gas mixer reduces the fresh-gas flow
FG flow automatically. This reduction takes place
depending on the set tidal volume VT and the set
respiratory rate RR.
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.
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.
If minimum-flow or low-flow settings are used,
flush the breathing system regularly.
