Less usual ventilatory modes: Mandatory Minute Ventilation and Adaptive Minute Ventilation

Victor Perez, Jamille Pasco

Abstract

Weaning or liberation from mechanical ventilation is an important goal for critical care patients and in many cases this process spends most of the time in intensive care units.  The optimal strategy to wean critical care patients isn’t elucidated. Computerized or automated weaning has been used to improve this process.

Taxonomy of a ventilatory mode includes mention of the control variable, breath sequence, and targeting scheme. Intermittent mandatory ventilation (IMV) is a type of breath sequence in which it coexists spontaneous and mandatory breaths. It could be used for weaning in some patients. There are five varieties of IMV each with its own advantages and disadvantages. We’ll review two less usual ventilatory modes with IMV breath sequence: mandatory minute ventilation (Draeger) and its evolution, adaptive ventilation mode, specifically adaptive minute ventilation (Mindray).

Keywords: weaning, taxonomy, spontaneous breath, mandatory breath, intermittent mandatory ventilation.
