- Inflate the tracheal cuff and confirm bilateral and equal breath sounds.
- Inflate the bronchial cuff (rarely >2 mL of air needed) and confirm bilateral and equal breath sounds (ensures that the bronchial cuff is not obstructing the contralateral hemithorax.
- Selectively clamp each lumen and confirm one-lung ventilation.
- Perform bronchoscopy using a fiberoptic bronchoscope. Nearly half of tubes thought to be properly positioned by auscultation and examination were not confirmed to be so by bronchoscopy (see Table 37-7: Use of a Fiberoptic Bronchoscope to Verify Proper Placement of a Double-Lumen Tube).
