5.1 About Adaptive Bi-Level
In VersaMed’s Adaptive Bi-Level mode the iVent can
accommodate high leak situations -- for instance when using a
facemask (sometimes referred to as non-invasive ventilation) or
pressure support for high leak ET tube ventilation (Passy
Muir and cuffless applications). It is an important component
in the arsenal of therapies that can be applied to patients
presenting with respiratory insufficiency.
Adaptive Bi-Level mode is a combination of two standard
modes of ventilation: Pressure Control, where the inspiratory
and end expiratory pressures, I-Time, and Breath Rate are
specified; and Pressure Support Ventilation where breath
termination can be controlled by the patient.
