Setting The Fresh Gas Flow; Selecting The Ventilation Mode; Man/Spont Ventilation Mode; Manual Ventilation - Dräger Julian Instructions For Use Manual

Setting the fresh gas flow

1 Press the softkey »L/min«.
The key field is highlighted against a light background.
Set and confirm the fresh gas flow by means of the
rotary knob.
Julian is fitted with an electronic O
system to avoid hypoxic gas mixtures. For fresh gas flow
settings below 1 L/min, the O
automatically increased to a value corresponding to an
O flow of 250 mL/min. If this control system is
2
activated, the O value is highlighted in addition to the
2
active softkey »L/min«.
Version with fresh gas failure detection (optional):
During operation, Julian checks that the bellows are
sufficiently full.
If the message „Fresh gas ? !!" appears:
Increase the fresh gas flow
The default settings valid whenever Julian is switched on
can also be modified; see "Setting default values" on
page 82.
