7.3.4 O
2
therapy
O
2
therapy is not a ventilation mode in the strict sense. Its purpose is
rather a dosed enrichment of the breathing air with oxygen in case of
breathing problems and to increase the O
2
level in the arterial blood. The
O
2
concentration and flow can be set on the ventilator. Monitoring by the
EVE
TR
requires the connection of an (optional) SpO
2
sensor. The oxygen
is delivered by a nasal tube, nasal cannula, or oxygen mask.
NOTE
When using an O
2
nasal cannula, the set maximum flow 6 l/min should not be
exceeded.
7.3.5 High flow O
2
therapy
High flow O
2
therapy is available only in Neo mode and is actually not a
form of ventilation; instead it serves as ventilatory support. Oxygen is
supplied using "high flow nasal cannula". O
2
concentration, flow, and
operating pressure limit (PAW alarm limit) can be set on the ventilator
The respirator monitors this only if an SpO
2
sensor (optional) is
connected.

ATTENTION
The operating pressure, not the patient's inspiration pressure, is displayed on the
ventilator. If the operating pressure is decreased via the PAW alarm limit, the flow to
the patient also decreases.
