should be prevented. Connect the sample gas outlet of the Compact Airway Module (at the front
panel) to the scavenging system according to one of the following procedures.
1. Connect an exhaust line to the sample gas outlet and to the ventilator reservoir. The reservoir

CAUTION Make sure that the sample gas is not removed from the Compact Airway Module
under a strong suction. To prevent this, there must always be an opening to room

Module and cause inaccurate readings or internal damage.
