decompression illness, the system should be flushed every 10-15 minutes by
emptying the bag and then refilling by depressing the Oxygen Flush.
8.
For a casualty who may have inhaled toxic gas, keep the flow rate at 8 L/min
to assist in the excretion of toxic gas from the lungs and leave the APL exhaust
valve open throughout the resuscitation.
9.
Ask a conscious casualty to breathe normally. Reassure further and advise that
the mask may make them feel claustrophobic, but this is normal.
10. Monitor the breathing by observing movements of the breathing bag.
11. Adjust the flow rate as necessary to compensate for leaks. The APL exhaust
valve in the open position automatically vents excess gas.
12. Carefully monitor the casualty’s condition and never leave the casualty
unattended.
13. Carefully monitor the oxygen supply and remove the mask prior to the supply
becoming exhausted.
b) Using the Non-rebreathing therapy mask with the reservoir bag
Provides about 50 % oxygen. Used as an alternative to the closed circuit or if there
is a second breathing casualty requiring oxygen therapy (in this case connect the
oxygen tubing from the non-rebreathing mask to the 8 L/min nipple restrictor
assembly). The mask incorporates a safety vent which enables the patient to
entrain air from the atmosphere if the reservoir bag empties during inspiration.

Explain and re as s ur e t he pat i ent what i s i nvol ved during the
administration of oxygen.
2.
If practicable turn an unconscious, breathing patient into the left lateral
position. Take special care if a spinal injury is suspected.
3. Turn the oxygen cylinder valve ON (anti-clockwise).
4.
Ensure the oxygen tubing is not kinked and attach it firmly to the flow outlet
on the KDK85 Autovalve. Set the flowrate to 8 L/min and press the Oxygen
Flush to rapidly fill the reservoir bag.
5.
Position the non-rebreathing therapy mask over the mouth and nose and
mould the metal band over the bridge of the nose to achieve a better seal and
comfortable position. Place the supporting elastic band around the patient’s head
above the ears and tighten until comfortable and secure. Observe the reservoir
bag to ensure it remains inflated. However, if it does deflate, the patient will
be able to entrain air through the safety vent.
6.
Increase or decrease the oxygen flow to ensure the reservoir bag remains
adequately distended (i.e. it should not completely empty after breathing in)
7.
Carefully monitor the patient’s condition: DO NOT leaves the patient
unattended.
8. Carefully monitor the oxygen supply. Replace the cylinder BEFORE it is
completely exhausted.
Management of A Non-Breathing Casualty
o provide the highest oxygen concentration (90-100 %) to a non- breathing casualty, the
closed circuit should be used whenever possible. Clear the patient’s airway before
commencing resuscitation.
