Proportional assist ventilation (PAV) is designed to adjust inspiratory pressure proportionally to the patient's inspiratory demand. PAV+ (Puritan Bennett 840/980 ventilator;Covidien) automatically measures the elastance and resistance of the respiratory system during spontaneous breathing and delivers adequate pressure to meet the flow and volume demands that are simultaneously measured on a breath-by-breath basis. Therefore, PAV+ provides pressure which is proportional to the lung mechanics and the patient's inspiratory demand. Previous studies have demonstrated that PAV+ may improve patient-ventilator interactions. PAV+ also monitors the work of breathing, which prevent diaphragmatic atrophy. For these reasons, PAV modes may be efficient in the liberation process.
