Oxygen Enrichment For Bronchial Suction - Dräger Evita 2 dura Instructions For Use Manual

Oxygen enrichment for bronchial suction

To avoid any risk of hypoxia during bronchial suction,
Evita 2 dura offers a programme for oxygen enrichment during
the removal of secretions.
After the programme is started, Evita 2 dura ventilates the
patient in the selected ventilation mode for an initial oxygen
enrichment phase of 180 seconds. In adult mode, the
ventilator supplies 100 % oxygen by volume, and in paediatric
mode it delivers the set O
2
(for example: setting = 60 % by vol.; administered = 75 % by vol.)
When the ventilator is disconnected for suction, Evita 2 dura
interrupts the ventilation. During the suction time, the audible
alarms are suppressed, so that the suction routine is not
disturbed.
After suction and automatically recognised reconnection,
Evita 2 dura delivers an increased O
final oxygen enrichment phase of 120 seconds. In adult mode,
the O concentration is 100 % by volume. In paediatric mode,
2
the enriched concentration is 25 % higher than the set
concentration*.
During suction and for 2 minutes afterwards, the lower alarm
limit for the minute volume is switched off.

Evita 2 dura ventilates the patient in the set ventilation mode
with increased O concentration: 100 % O
2
mode, and a 25 % higher O
in paediatric mode.
If no PEEP greater than 4 mbar is set, a PEEP of 4 mbar will
be automatically activated. This PEEP enables the Evita 2 dura
to detect subsequent disconnection.
The other ventilation parameters remain unchanged.

The remaining time is counted down continuously. This initial
oxygen enrichment lasts for a maximum of 180 seconds.
During this time, Evita 2 dura waits for a disconnection for
suction.
If there is no disconnection after expiry of the 180 seconds,
the oxygen enrichment programme is automatically terminated.
