Abstract:
This case demonstrates a novel preoxygenation technique in a patient with difficult access to the airway after a traumatic facial injury. To find a solution, a fusion of oxygenation equipment was trialed by altering and combining a tracheostomy mask and the tubing of an Optiflow circuit from which the nasal cannula component had been removed. This novel combination delivered high-flow humidified oxygen (60 L/min) orally, avoided further facial injury, and was well tolerated by the patient. Effective preoxygenation was confirmed by arterial gas measurements. This study supports the use of this novel Optiflow-tracheostomy mask fusion device in appropriately selected cases.

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
Oxygen Delivering System I: Nasal Cannula and Face Mask
Nasal Cannula
A nasal cannula is a lightweight tube split at one end into two prongs and placed in the nostrils. It is typically used to deliver low to medium levels of oxygen.
Suggested flow rate: The suggested flow rate for a nasal cannula typically ranges between 1 and 6 L/min.
