Button assignment:
the meaning of adjacent buttons is defined in fields k to r in Figure 5-2 . Field k
and its button are always used to acknowledge alarms. In some menus, two different parameters
are assigned to a single button in fields n to r. In this case, the operator can press the relevant
button several times to switch between the two parameters.

Basic CPAP settings
The CPAP therapy generated in the Medijet
®
is largely determined by two factors: the flow volume (
Flow
)
emitted by the CPAP driver and the oxygen concentration (
FiO
2
) contained in this. These two fundamental
factors are set in the same way in all modes and are transferred when the operator switches from one mode
to another.
Flow:
Press button a as shown in Figure 5-2 to change the flow value that has been selected. This action activates the
flow setting (a blue background appears). The target value can then be changed by turning the dial. As this also
changes the flow volume produced by the medinCNO
®
, the operator can see the effect of this change on the
CPAP pressure produced as shown in graph h in Figure 5-2. The operator can terminate activation, and thereby
the ability to change the flow value, by pressing the dial. If the dial is not pressed to conclude the flow change,
the medinCNO
®
still accepts the flow volume change.
If the flow value is altered in situations when no patient is connected to the Medijet
®
, the Medijet
®
prong
adapter must be closed by the operator during this process (e.g. by holding it shut). This simulates the CPAP
pressure which is produced. If a patient is connected to the Medijet
®
during flow adjustment, the prong or
mask must be checked for leaks before any adjustment is made as the presence of leaks could affect the CPAP
pressure which is produced.
The medinCNO
®
automatically produces a flow of 7 L/min on start-up. The user must adjust this flow while
keeping the Medijet
®
prong adapter closed until the flow produces the desired CPAP pressure.
Warning:
Since the set basic flow (
Flow
) and additionally the set push flow (
F
insp
) are emitted during a push, an increase
in the basic flow also increases the CPAP pressure during a push. Therefore, the setting for
F
insp
must always be
monitored when the
Flow
setting is changed. (Adjustment according to chapter 5.4)
Please note:
The mask or prong should always be checked for leaks before adjusting the flow that has been selected, as the
presence of leaks affects the CPAP pressure which is produced.
If the leak assist function is activated in CPAP mode, it is automatically deactivated by adjusting the flow. If it
is once again desired, it must then be manually restarted (see chapter 5.7).

oxygen concentration:
Alter the oxygen concentration by using button b in Figure 5-1 to highlight the current oxygen concentration
and then turning the dial to select the desired value. Press the dial to confirm the new figure. This completes
the process of adjusting the oxygen concentration. It is only now that the medinCNO
®
alters the oxygen
concentration in the patient flow. If the oxygen concentration adjustment is not confirmed by pressing the dial,
the medinCNO
®
continues to blend the oxygen concentration that was set before the target value was adjusted.
