B Modes of ventilation
The modes that permit spontaneous breathing use flow (the
ETS setting) to cycle into exhalation. As a backup for pediatric
and for all patients in NIV mode, time (the Ti max setting),
serves as a backup. This backup mechanism can prevent the
possibility of endless inspiration resulting from a large leak, and
is critically important in the NIV mode.
An automatic adjustment mechanism maintains PEEP stability
even with a moderate breathing circuit leak.
