Supraglottic airways (SGAs) are advanced airway devices designed to provide effective airway management and ventilation when basic airway interventions are inadequate. These devices can be inserted rapidly and may serve as an alternative to endotracheal intubation in appropriate patients.

Common supraglottic airway devices include:

  • i-gel
  • Air-Q3 Supraglottic Airway
  • King LT
  • Laryngeal Mask Airway (L.M.A.)

Supraglottic airways may be considered in patients who:

  • Cannot adequately maintain their airway
  • Require assisted ventilation
  • Are unconscious or unresponsive
  • Cannot be effectively managed with basic airway adjuncts alone

Advantages of supraglottic airways include:

  • Rapid insertion
  • Minimal interruption to patient care
  • Improved ventilation compared to basic airway adjuncts
  • Useful alternative when endotracheal intubation is unsuccessful or unavailable

Following insertion, providers should:

  • Confirm adequate chest rise
  • Monitor oxygenation and ventilation
  • Reassess airway effectiveness

While supraglottic airways provide significant airway support, they do not replace ongoing airway assessment and management.

Remember: The goal is effective oxygenation and ventilation — not placement of a specific device.
