A new cricothyrotomy cannula.
A simple, easily constructed cricothyrotomy cannula and its method of use are described. Experiments have demonstrated that the instrument admits adequate air to sustain life without causing trauma to the posterior laryngeal wall. The dimensions allow the concurrent use of the FG10 suction catheter. An accessory device which enables single instrument cricothyrotomy is also described.
