6.4. Instrument
Activate the instrument by depressing the catch. No damage is done to
the Ambu Man nor the instrument during chest compression in case
the instrument is not activated (pulled out), see
t
.
During the CPR test, the side of the monitoring instrument visible to
the trainee may be concealed by the cover plate, see
y
.
6.5. Carotid pulse
Fit the tube with bellows onto the tube connector.
The carotid pulse can now be activated manually by the instructor by
compressing the bellows, see
u
.
6.6. Adjusting chest stiffness
The stiffness of the chest can be adjusted as required by loosening the
thumb screw on the back of the manikin: For reduced stiffness set to
'LOW' position, for increased stiffness set to 'HIGH' position, see
i
.
The values shown, 6N/mm and 11 N/mm (N=Newton), indicate the
force which must be applied to compress the chest by 1 mm.
Example: Compressing the chest by 40 mm at the 'LOW' setting, a
force of 240 Newton (6Nx40mm) must be applied.
The normal setting is 'MEDIUM' corresponding to approx. 8.5 N/mm.
The Ambu Man can be supplied as a full body model with arms and
legs, see
o
.
Training may now be started in accordance with the appropriate
training programme, see
p
and
[
.
NOTE: Remember to change head bags and face pieces for each
new trainee.
7. Instructions
The Ambu Man is designed to meet the training recommendations of
the International Guidelines 2000 committed to by the American Heart
Association (AHA) and the European Resuscitation Council (ERC).
In general, however, it is recommended that instructions should be
based on the techniques and provisions applicable in the country in
which training will take place.
Ensure there is free access to the airway by hyperextending the head or
using jaw thrust manoeuvre, see
]
and
A
.
Use the following techniques, see
S
:
• Mouth-to-mouth ventilation
• Mouth-to-nose ventilation
• Mouth-to-mask ventilation
• Resuscitator/mask ventilation
The movements of the chest can be clearly observed during insufflation
and expiration. The insufflated volume is displayed directly on the
monitoring instrument. The expired air can be felt and heard from the
mouth and nose of the Ambu Man with no risk of infection, as the air is
the same as that insufflated by the trainee into the head bag, see
D
.
Accidental stomach inflation is simulated and can be observed in the
stomach region and viewed directly on the monitoring instrument.
External chest compression can be practised, and the depth of com-
pression will be displayed on the monitoring instrument in millimetres.
It is possible to adjust the stiffness of the chest to simulate a patient
with a soft, normal or hard chest. To ensure that the correct point of
compression is applied during chest compression, the instrument also
provides indication of incorrect hand positioning, see
F
.
The carotid pulse can be felt on both sides of the larynx during chest
compression, or simulated manually by the instructor, see
G
.
