4.4 Mask ventilation
Ventilation must be carried out if spontaneous
breathing cannot be established once the airways
are cleared and the patients spontaneous breathing
must be assisted or controlled if it is inadequate.
Proceed as follows:
•
lay the patient on his back
•
extend the head and neck
•
pull the red ring on the COMBIBAG relief valve
upwards (pressure limit 20 mbar (2 kPa
(≈ 20 cmH
O)))

•
C-grip: left hand lifts the lower jaw back and
seals the mask over the mouth and nose
•
rhythmically squeeze and release the appropri-
ate segment (adult and infant) at the recom-
mended frequency
•
if necessary, insert a Wendl-airway through the
nose or use a Guedel-airway to improve access
to the nasopharyngeal cavity
•
the mask must seal tightly
•
the red ring on the relief valve should be pushed
down (pressure limit 60 mbar (6 kPa
(≈ 60 cmH
O))) in exceptional cases only, where

adequate ventilation still cannot be achieved.
However, inflation of the stomach is not then ex-
cluded and must be considered!
