Q

What are some advantages to using a laryngeal mask airway?

A
  1. They can be used whenever a face mask can be used.
  2. Allows one handed ventilation
  3. If properly inserted it can form a seal around the larynx
  4. Less stimulating than endotracheal intubation
  5. Can manage a difficult airway
