4. Operating instructions
4.1 Introductory remarks
Although it is commonly assumed that resuscitation
should be carried out only after respiratory failure
has been confirmed, it must be emphasized that it
should be commenced as soon as symptoms such as:
• cyanosis and/or
• visibly reduced respiratory movements and/or
• very low respiratory frequency and/or
• diminished respiratory murmur and/or
• diminished air flow
indicate dangerous suppression or restriction of
spontaneous breathing. This ensures that all forms
of hypoventilation, such as dead space breathing
and breath “rattling” are covered.
4.2 Checking the function
The function of the COMBIBAG resuscitation bag
should be proven before each use and can be
checked in a few seconds as follows:
• Squeeze the bag with the right hand and cover
the patient valve with the left hand: regardless
of the relief valve setting, air can be felt and
heard to flow into the left hand.
• Release the bag: it expands rapidly and air can
be heard to flow through the inlet valve.
