INVERSE RATIO VENTILATION

Course overview

INVERSE RATIO VENTILATION (IRV) IS AN ALTERNATIVE STRATEGY FOR MECHANICAL VENTILATION THAT REVERSES THE CLASSICAL INSPIRATORY/EXPIRATORY PARADIGM. THIS IS ACHIEVED BY MODIFYING THE INSPIRATORY TO EXPIRATORY (I:E) RATIO, TYPICALLY WITH THE INTENTION TO INCREASE OXYGENATION BY INCREASING THE MEAN AIRWAY PRESSURE (MAP). THIS ACTIVITY DESCRIBES THE INDICATIONS FOR AND CONTRAINDICATIONS TO INVERSE RATIO VENTILATION AND HIGHLIGHTS THE ROLE OF THE INTERPROFESSIONAL TEAM IN THE MANAGEMENT OF VENTILATED PATIENTS.
