Prediction of Weaning Outcomes by Using Rate of Change of Rapid Shallow Breathing Index

Prediction of Weaning Outcomes by Using Rate of Change of Rapid Shallow Breathing Index

This trial examines weaning outcomes using the rapid shallow breathing index rate.

We hypothesize that the trend of the Rapid Shallow Breathing Index or RSBI rate, is a better predictor of weaning outcome than the RSBI as a single value during the weaning trial. patients are recruited during a weaning trial on t-piece and the RSBI during what the RSBI is measured periodically. The outcome is ventilatory status at 24 hours after the weaning trial.

Inclusion Criteria:

• Requires need of mechanical ventilation for > 48 hours with a tube size no smaller than 7.5

Exclusion Criteria:

• Healthy volunteers
