Dräger Julian - In the Event of a Gas Failure; In the Event of a Major Hardware Fault

In the event of a gas failure
Julian activates an alarm if the O2 or AIR or N2O supply
fails.
● Open the valve on the corresponding backup gas
cylinder on the rear of the workstation.
● Reconnect the central gas supply.
If there is no backup supply of gas available, Julian
replaces the set gas mixture with AIR or O2:
Julian delivers 100 % AIR if the O2 supply fails.
Julian delivers 100 % O2 if the N2O supply fails.
Julian delivers 100 % O2 if the AIR supply fails.
The amount of fresh gas flow (L/min) remains constant.
Fresh gas metering is still possible even in the event of
failure of one of the gases. For example, if the N2O
supply fails, AIR can be selected as the carrier gas.
In the event of a Major Hardware Fault
such as the failure of the fresh gas mixer, the message:
SYSTEM FAULT!!!
will be displayed.
In the event of total system failure including the screen,
an alarm will sound for about 30 seconds.
In such cases Julian switches to MAN/SPONT ventilation
mode.
Version without rotary knob for O2 emergency
metering:
Julian automatically delivers an O2 flow of 4 L/min*.
This O2 flow bypasses the Vapor unit, and so the patient
no longer receives any anaesthetic agent.
Version with rotary knob for O2 emergency metering:
● Set rotary knob for O2 emergency metering to the
desired O2 flow.
Range 0 to 12 L/min.
This O2 flow flows through the Vapor unit.
● Check the Vapor unit setting.
● Ventilate the patient manually!
* Can be adjusted to up to 8 L/min O2 by DrägerService.
