Operation
Apnoea ventilation
Apnoea back-up ventilation is only applicable when
using the SpnCPAP mode. In the event of an apnoea,
the ventilator will automatically activate volume-cont-
rolled mandatory ventilation (VC-CMV).
When an apnoea occurs, the device simultaneously is-
sues an alarm signal and switches to volume controlled
ventilation with the parameters respiratory rate RRapn,
tidal volume VTapn, and the maximum airway pressure
Pmax when the apnoea time Tapn has been reached.
The ventilation time ratio I:E = 1:1.5 and the plateau
time Tplat % = 0 are preset during apnoea ventilation.
Setting apnoea ventilation
On the display:
1 Set Tapn with the rotary knob to a value between 15
and 60 seconds.
The parameters RRapn and VTapn, which are required
for setting apnoea ventilation, are now displayed:
2 Set RRapn and VTapn.
3 Set Pmax. This determines the maximum airway
pressure allowed during apnoea ventilation.
To end apnoea ventilation
z Press the Alarm Reset key.
The ventilator resumes ventilating with the original
mode and parameter settings.
To disable apnoea ventilation
z Set Tapn to OFF.
NIV – Non-invasive ventilation
(mask ventilation)
Use of NIV
NIV can only be activated as a supplementary function
in the ventilation modes SpnCPAP (/PS),
PC-BIPAP (/PS), VC-CMV / AF, VC-AC / AF, and
VC-SIMV / AF. The Oxylog 3000 plus automatically ad-
justs to the requirements of mask ventilation. Mask lea-
kages are detected by the device and compensated for.
Therefore, the displayed measured values VTe and
MVe do not include the leakage. The leakage alarm is
inactive.
When NIV is switched on, the supplement NIV appears
in the ventilation mode window.
