Instructions for use Primus Infinity Empowered SW 4.5n
The fresh-gas flow (L/min) remains constant.
Fresh-gas delivery remains operational even fol-
lowing a gas failure. This means that AIR or 100 %
O
2 can be set as carrier gas if N2O fails.
If the central gas supply for O
2 and AIR fails and no
backup supply is available, operation can be con-
tinued with ambient air in automatic ventilation
modes.
This is possible due to the fact that the electrically
driven ventilator does not require driving gas for op-
eration. If the fresh-gas volume is insufficient, the
missing quantity is refilled with ambient air if the
breathing bag is removed.
1 Remove breathing bag.
2 Perform automatic ventilation.
The failure of the central gas supply may lead to the
failure of connected devices.
The cylinder valve on the corresponding reserve
gas cylinder must be closed again after restoring
the central gas supply.
CAUTION
Risk of patient injury
Primus Infinity Empowered delivers 100 % O
2 if
AIR or N2O has failed.
Note the contra-indications for 100 % O
2.
WARNING
Risk of patient awareness
If a complete gas supply failure occurs, fur-
ther operation is guaranteed by supplying the
anesthesia machine with ambient air. Anes-
thetic agents will no longer be delivered and
the inspiratory gas composition will be di-
luted.
Carefully monitor the gas mixture and, where
necessary, use intravenous anesthetic
agents.
WARNING
Risk of gas supply contamination
When the central gas supply is connected, the
smallest internal leakage can cause contami-
nation of the supply gases.
Disconnect the compressed gas hoses from
the terminal unit if the central gas supply fails
during operation.
CAUTION
Risk of increased ambient gas concentrations
If the breathing bag is not attached, expiratory an-
esthetic agents can escape from the breathing
system.
Ensure sufficient ambient air circulation.
CAUTION
Risk of supply failure
If the valves remain open when connected to the
central gas supply, gas may be withdrawn from
the reserve gas cylinders.
Close cylinder valves whenever the central supply
is sufficient.
