The ventilator significantly overestimates the RSBI value compared to the standard technique by Wright spirometer. The average RSBI vent value among 5 time points (0, 15, 30, 45, and 60 s) was found to best correlate with RSBI standard.

47 patients were enrolled.

The RSBI vent value was significantly higher than the RSBI standard value for every comparison.

This prospective cohort study included mechanically ventilated patients who were ready to wean.

At the beginning of spontaneous breathing trial using the flow-by method, RSBI was measured by two different techniques at the same time.
