RSBI Calculator – Rapid Shallow Breathing Index
Evaluate mechanical ventilation weaning success (Tobin's Index)
Critical Care Guidelines: The Rapid Shallow Breathing Index (RSBI) is calculated as $\text{Respiratory Rate} / \text{Tidal Volume (L)}$. An RSBI below $105$ generally indicates successful extubation / weaning potential. Enter patient ventilator parameters below.
