Ambu Mark IV Manual

1. Warnings and cautions

WARNINGS
• Insufficient, reduced or lack of ventilation may lead to brain
damage in the ventilated patient.
• Should only be used by personnel trained in performing resusci-
tation. It is important to obtain a tight seal between the face and
the mask. Otherwise, this may cause reduced ventilation or no
ventilation. Make sure that such personnel are made familiar
with the contents of these instructions for use.
• Watch the movement of the chest, and listen for the expiratory
flow from the valve to check the efficiency of the ventilation.
Failure to do so may result in insufficient ventilation.
• Switch IMMEDIATELY to mouth-to-nose or mouth-to-mouth ven-
tilation in accordance with local guidelines if efficient ventilation
cannot be obtained with the device. Failure to do so may result
in insufficient ventilation.
• Do not smoke or use open flames when using oxygen - fire may
result.
• Do not use the resuscitator in toxic or hazardous atmospheres as
this may harm the patient. See Section 5.4 for further details.
• Once the override cap has been mounted on the pressure-limit-
ing valve and the whole hand is used for compressing the Ambu
Mark IV Baby resuscitator, the pressure-limiting outer cover is
prevented from expanding, meaning that in case of extremely
heavy compression, a pressure as high as 8-10 kPa (80-100
cmH O) is created in patients with low lung compliance.

CAUTIONS
• According to US federal regulations, this product may only be
sold by or on the order of a physician (only applies in the USA
and Canada).
• It is important to check that all parts of the resuscitator are in
good condition, that it is properly assembled, and that a com-
plete functional test is carried out every time the device has been
disassembled - also before the initial use.
• This functional test, which is described in chapter 8.1, should
also be carried out every time the device is taken into use. Check
of correct function of the pressure-limiting valve according to
Section 8.2 should also be performed immediately before use.
• If the resuscitator and its accessories are kept on standby for
emergency situations, the entire equipment should be checked
regularly to ensure that it is functional.
• Avoid the use of or contact with oil or grease as they may dam-
age the materials of the resuscitator. In case of contact, the sur-
face must be thoroughly cleaned.
• Do not use oil or grease in close proximity to oxygen equipment
- fire may result.
• Do not force the outer cover of the bag to bulge locally by clos-
ing the patient connector and pressing the bag so hard with
your hand that a local bulge appears on the outer cover - this
has an extreme impact on the material.
• The tube connector may only be used for pressure monitoring.
The cap must always be put on the connector when pressure
monitoring does not take place.
