Endotracheal Tubes (Figure 9.14)

9.10Endotracheal Tubes (Figure 9.14)

  • Most secure airway
  • Regardless of size, all have 15 mm connectors for circuit or BVM adaptor
  • ETT size represents internal diameter in millimeters
  • Most are cuffed, may be uncuffed (mostly in peds)
  • Cuff [13]
    • Prevents aspiration and leaks during positive pressure ventilation (PPV)
    • Becoming more popular than uncuffed
    • Ideal cuff pressure is 20–30 cm H2O
      • Allows for adequate delivery of PPV
      • ↓ Risk of aspiration
      • ↓ Risk of ventilator‐associated pneumonia
  • Murphy’s Eye
    • Distal to cuff
    • Prevents complete obstruction of the ETT even if bevel is occluded against tracheal wall
Two schematic diagrams of endotracheal tubes read oral E T T and nasal E T T.

  • Head Flexion
    • ETT moves toward carina [14]
