Minitrach

We could use a minitrach in Fig 1 with the same effect. These are typically 4 mm internal diameter and have no cuff. They are primarily designed to allow airway toilet (suction) but can facilitate oxygen delivery.

They are too small to provide any ventilation or removal of carbon dioxide and so can only be considered an emergency method of oxygenation.

Minitrachs are sometimes used when preparing to decanulate a patient. The minitrach can remain in the stoma and keep it patent in case a tracheostomy tube needs to be re-inserted.

Minitrachs can also be inserted through the cricothyroid membrane.
