Depending on the FiO
2
alarm preset in the service menu, the change in the oxygen concentration affects the
limits of the oxygen alarm:
- FiO
2
alarm automatic : At the same time as the change in the oxygen concentration, the limits for
the oxygen alarm are also adapted to the new oxygen concentration.
- FiO
2
alarm manual : The change in the target oxygen concentration does not affect the limits of
the oxygen alarm. After changing the oxygen concentration, these limits have the same values as
before the change. They can only be adjusted manually to the new oxygen values. For this
purpose, the user must open the
Alarm settings menu and manually update the alarm thresholds
(see chapter 5.12).
Please note:
The oxygen concentration in the patient flow does not change until the new oxygen concentration has been
confirmed. Only then can the effect of the changed oxygen concentration on the patient be observed.
As long as an O
2
flush is active, the target oxygen concentration FiO
2
cannot be changed. Only after a manual
premature end or after an automatic end of the O
2
flush can the FiO
2
setting be changed once again (see
chapter 5.5).
5.4 Push
In addition to the basic CPAP mode, the medinCNO
®
can increase the CPAP pressure if necessary for a short
time. These short periods are called ‘pushes’ and can be used to stimulate the patient. A push is determined
by the additional flow used for it and its duration.
Additional flow during a push - F
insp
:
In field c in Figure 5-1, set an additional flow F
insp
by pressing the button to activate the setting, turning the dial
to select a value which immediately becomes active for the next push and then pressing the dial to confirm. If
the dial is not pushed, the change is made nonetheless. As flow during a push, the medinCNO
®
emits the sum
from the basic flow Flow set in Figure 5-1 field a and the additional push flow F
insp
.
As an additional push flow F
insp
, a value between 0 L/min (that is, essentially no push is triggered) and a
maximum value dependent on the basic flow set can be set. The maximum value is 17.5 L/min minus the set
basic flow Flow .
Warning:
A push does not generate a breath; instead it can only stimulate but not ventilate!
The setting F
insp
may only be changed in small increments. The effect of each small increment (= CPAP pressure
that develops during a push) must be monitored by triggering a manual push or by waiting for an automatic
push. It should be noted that any change becomes immediately active for the next push, even without pressing
the dial.
The CPAP pressure that develops during a push depends on the leakage of the CPAP system (particularly the
leakage from prongs or the mask). An increase in the push flow by +1 L/min can cause an increase of up to 3.5
mbar in the CPAP pressure.
