Principles of operation

Therapy types and application modes

O therapy
2
O therapy can be used for patients with
2
independent breathing. The continuous flow is
applied via an oxygen mask, a hood or nasal
cannula. The O concentration and the flow can be
2
adjusted.

Non-invasive ventilation (NIV)

Non-invasive ventilation by mask for patients with
spontaneous breathing
Leakages are greater with non-invasive ventilation
than with invasive ventilation. Savina 300 takes into
account the leakages in the NIV application mode
accordingly. The inspiratory trigger is automatically
adapted to the measured leakage. This prevents
auto-triggering due to a flow trigger which has been
set too low and prolonged inspirations.
The inspiratory tidal volume is typically far higher
than the patient's tidal volume. The expiratory tidal
volume is slightly lower than the patient's tidal
volume. The measured values for tidal volume are
leakage-corrected and indicate the patient's actual
tidal volume. In ventilation modes with AutoFlow,
the corrected measured values are set. During
volume-controlled ventilation, the inspiratory
volume escaping through the leakage is
additionally supplied.
Monitoring during NIV
In order to prevent artifacts in the case of very high
leakages, the following alarm limits may be
deactivated:
– MV
– VT
– T
apn
244
To delay the high-priority alarm message Airway
pressure low, the delay time T
set between 0 and 60 seconds for the lower alarm
limit of the airway pressure.
The leakage minute volume MV
a percentage of the measured minute volume in the
Trends/Data dialog window. The tidal volume VT
indicates the volume actually reaching the patient.
VT is the delivered tidal volume minus the volume
lost through leakage during inspiration.
