Surgical cricothyroidotomy can restore ventilation and oxygenation quickly in the CICV scenario. It can result in serious complications, but these are very unlikely to be life threatening and should not discourage attempt.
Surgical cricothyroidotomy enables the passage of a cuffed TT tube into the trachea, thus allowing conventional ventilation .
It is a temporizing measure prior to definitive airway management.
It should be practiced regularly with a manikin.
