rapid shallow breathing index (RSBI)

The Rapid Shallow Breathing Index (RSBI) is a measurement used by healthcare providers to assess if a patient is ready to breathe on their own after mechanical ventilation. It is calculated by dividing the number of breaths a patient takes per minute by the amount of air they breathe in with each breath (tidal volume). A low RSBI indicates that a patient is likely ready to be weaned off ventilation, while a high RSBI suggests they may still need support. Overall, it helps guide safe and effective weaning from ventilator support.
