rapid shallow breathing index

Abbreviation: f/TV; RSBI.
The ratio of the respiratory rate (f) and the tidal volume (TV) of a patient treated with mechanical ventilation while breathing on a T-piece (or at minimal levels of positive airway pressure or pressure support). Levels less than 105/min/L indicate that a patient may be able to be weaned successfully from the ventilator and breathe unassisted.
