AB  - Introduction: Weaning is gradual removal of mechanical ventilator support. Different predictors are used for weaning initiation. This study is designed to investigate the rapid shallow breathing index (RBSI) as a predictor for successful weaning.Materials and methods: We did this cross-sectional study on 70 patients who had mechanical ventilation for more than 48 hours in respiratory care unit (RCU) in Tehran Labbafi Nejad hospital. We measured RBSI, and then evaluate the value of RBSI for successful extubation.Results: 63 (90%) Patients had RBSI ≤105 (Breath/min/L), among them 49 (77%) patients had successful weaning and did not need re-intubation but the rest had unsuccessful weaning (P=0.001). Weaning index mean for patients with successful extubation was 66±57.2 and for patients with unsuccessful extubaion was 76.9±28.1. We could not find a significant difference between means (P=0.433).Conclusion: Our findings exhibited that RBSI has high sensitivity with low specifity. RBSI ≤80 is more reliable than RBSI≤105 as a predictor for weaning.
