How is RSBI calculated?
The rapid shallow breathing index (RSBI) is calculated as the ratio of tidal volume (TV) in liters to respiratory rate (RR) in breaths/minute: RSBI = TV/RR. a. With RSBI <105, a weaning attempt can be expected to be successful 78% of the time.

When do you use RSBI?
Clinicians can use the positive RSBI as an additional supporting data point to for the decision to extubate. Although the RSBI is generally accepted as helpful in predicting success of extubation, there is a dearth of convincing evidence that its application in decision-making leads to a change in outcomes.
