An RSBI (Rapid Shallow Breathing Index) of 110 indicates a higher likelihood of failure on a weaning trial from mechanical ventilation. An RSBI is calculated as the respiratory rate divided by the tidal volume in liters. A lower RSBI (typically less than 105 breaths/min/L) suggests a higher likelihood of successful weaning.
