Long term storage
For long term storage the resuscitator should be kept in closed
packaging in a cool place away from sunlight.
* Higher delivery pressure can be obtained by overriding the pressure-limiting valve.
The Ambu Oval Plus Adult is also available without pressure-limiting valve.
** Tested according to EN ISO 10651-4.
4. Principle in operation
The illustration (1) shows the ventilation gas flow mixtures into the bag and to and
from the patient during manual operation of the resuscitator. (a) Adult and paedi-
atric resuscitator, (b) infant resuscitator with closed reservoir, (c) infant resuscitator
with open reservoir.
The gas flow is similar when the patient is breathing spontaneously through the
device. The O
2
reservoir assembly is fitted with two valves, one allowing ambient
air to be drawn in when the reservoir is empty and one spilling out surplus
oxygen when the reservoir bag is full.

5. Instructions for use
Preparation
- If the resuscitator is packed in a compressed state, unfold by pulling on
the patient valve and the inlet valve.
- Fit the facemask and place all items in the plastic bag supplied with
the resuscitator.
- The integrity of the kits issued for storage ready for use should be inspected
at the interval established in the local protocol.
- Before use on the patient make a brief functional test as described in section 9.
- If connecting external devices to the resuscitator, make sure to test for functionality
and consult the instructions for use accompanying the external device.
