12.4 Manual breath

of a mandatory breath (standard or operator-set). You can
activate this function in all modes of ventilation.
To deliver a manual breath, press and release the key. DO NOT
quickly or repeatedly press the key.
If you try to start a manual breath during the early stage of
inspiration or the early stage of exhalation, the breath will not
be delivered.
12.5 Pneumatic and Aeroneb
®
nebulizer
WARNING
• DO NOT use an expiratory filter or HME in the
patient’s breathing circuit during nebulization.
Nebulization can cause an expiratory side filter
to clog, substantially increasing flow resistance
and impairing ventilation.
• To prevent the expiratory valve from sticking
due to nebulized medications, use only medica-
tions approved for nebulization and regularly
check and clean the expiratory valve.
