These are airway rescue devices which are inserted in the cricothyroid membrane. They are for patients who cannot be intubated or ventilated and who are becoming hypoxic. The equipment you would have readily available if you had a failed intubation and you could not ventilate your patient is:

• Needle cricothyroid puncture: a cannula if jet ventilation available, or a larger bore device like Quicktrach if no jet ventilation available
• Surgical cricothyroidotomy (any age): scalpel (number 20 blade), bougie, tracheostomy tubes or standard ET tubes (6-7 mm for adults)

Other possible equipment:

• Bullard laryngoscope
• Trachlight
• Aintree intubation catheter
• Combitube
