No Murphy Eye

The Murphy eye presents a challenge for cuff placement on smaller ETTs. Removing the Murphy eye on the Shiley™ pediatric ETT with TaperGuard™ cuff improves the margin of safety by2,4:

  • Allowing the TaperGuard™ cuff to be located closer to the tube tip, to help ensure the cuff is reliably placed within the trachea
  • Preventing the cuff from pressuring the laryngeal wall
  • Reducing the risk of endobronchial intubation
Features

A shorter, inverted TaperGuard™ cuff

Compared to traditional barrel-shaped cuffs, the shorter TaperGuard™ cuff on the Shiley™ pediatric ETT helps support cuff placement in the trachea and improves sealing. This low-volume, low-pressure, taper-shaped cuff5,6:

  • Uses less material, which helps ease insertion past the vocal cords
  • Requires less volume to fill the cuff
  • Decreases aspirations
  • Reduces cuff pressure on tracheal tissues
  • Helps ease insertion past the cricoid due to the shorter cuff-to tip distance
  • †Compared to the adult version.

  • The Shiley™ endotracheal tube is indicated for oral and/or nasal intubation of the trachea for anesthesia and for general airway management. The endotracheal tube is a sterile, single patient-use medical device not intended to be reprocessed (cleaned, disinfected/sterilized) and used on another patient. Expert clinical judgement should be exercised in the selection of the appropriate type and size endotracheal tube for each individual patient.
