Because of its ease of use, and relatively high predictive accuracy, the non-standardized RSBI is currently the most widely used parameter in the mechanical ventilation weaning process. The RSBI is defined as the ratio of the respiratory rate divided by the tidal volume (in liters). Having met all other weaning criteria, an RSBI of <100 indicates the patient is ready for extubation. This ratio is not standardized for baseline tidal volumes, i.e. does not account for the fact that people with different body masses will have very different normal baseline tidal volumes (normally 6 mL/Kg), which may drastically alter their calculated RSBI at any given respiratory rate. This project aimed to address the question of whether standardization of the RSBI will account for individual patient differences (based on weight, BSA, BMI, etc.) and reduce the calculation artifact due to normal physiologic variations in tidal volume with respect to the patient's body habitus. Another objective was to evaluate if the predictive value of a standardized RSBI exceeds that of the currently used non-standardized RSBI value, which would lead to an increase in the number of successful extubations and a decrease in the need to reintubate patients who were prematurely extubated
