RSBI (Rapid Shallow Breathing Index) — Weaning Readiness
Rapid Shallow Breathing Index (f/Vt) predicts successful extubation. RSBI <105 associated with successful weaning. Used with SBT and clinical readiness assessment.
Score interpretation
→ Extubate when RSBI <105 + passed SBT; have re-intubation equipment ready; consider high-flow nasal cannula (HFNC) post-extubation prophylactically; CPAP for obstructive physiology
→ Repeat SBT after 24h if failed; address reversible causes (fluid overload, secretions, pain, weakness); consider tracheostomy if >14 days ventilation likely; wean PEEP and FiO2 progressively
→ Continue mechanical ventilation; treat underlying cause; weaning protocol reassessment daily; physiotherapy (inspiratory muscle training); optimise nutrition; ICU team review; tracheostomy consideration
