rapid shallow breathing index

Indications

• assess readiness for endotracheal extubation
  • assess daily

Clinical significance

• if > 105, 95% probabilty extubation will be unsuccessful
• if < 105, 8-% probability extubation with be successful

Procedure

• a spontaneous breathing trial
• interruption of sedation
• place patient on a T-tube with no positive pressure, only supplemental oxygen, or
• adjust ventilator so that it delivers only enough pressure to overcome the endotracheal tube
• ratio of respiratory rate (breaths/minute) to tidal volume (liters)
