4.7 PEEP ventilation
Many disturbances in lung function (disturbances in
distribution, exudation, atelectasis, etc.) can be pre-
vented, or their effects reduced, by application of a
Positive-End-Expiratory-Pressure (PEEP).
A PEEP valve can be fitted directly to the exhalation
passage of the patient valve.
4.8 Volume measurement
To prevent hypo- or hyperventilation in the case of
prolonged manual resuscitation with the
COMBIBAG, a volumeter for measuring the expired
gas volume can be connected to the expiration
branch of the patient valve.
