What's the needle-like-tool that doctors poke into patients chest/lungs to keep them breathing?

Needle: Cricothyroidotomy. This procedure provides a temporary emergency airway in cases where there is obstruction at or above the level of the larynx, such that oral/nasal endotracheal intubation is impossible. Compared with an emergency tracheostomy, it is quicker and easier to perform and with fewer complications. It is a relatively quick procedure, taking up to about two minutes to complete.
