Design outcomes

Primary

MeasureTime frame
Diagnostic accuracy of VVI compared to D RSBI in predicting weaning outcomesTimepoint: Sustained spontaneous breathing for less than equal to 48 hours post extubation without reintubation or need for non invasive ventilation

Secondary

MeasureTime frame
1 Effectiveness of VVI alone in predicting weaning success 2 Associations between VVI and/or D-RSBI values and key clinical endpoints ventilator free days at 28 days ICU length of stay hospital length of stay and 28 day mortality Timepoint: 1 Ventilator free days at 28 days 2 ICU length of stay 3 Hospital length of stay 4 28 day mortality
