The nasal cannula (NC) is a device used to deliver supplemental oxygen or increased airflow to a patient or person in need of respiratory help. This device consists of a lightweight tube which on one end splits into two prongs which are placed in the nostrils curving toward the sinuses behind the nose, and from which a mixture of air and oxygen flows. [1]
The correct size airway is chosen by measuring the device on the patient: the device should reach from the patient's nostril to the earlobe or the angle of the jaw. [10] The outside of the tube is lubricated with a water-based lubricant so that it enters the nose more easily. [5] The device is inserted until the flared end rests against the ...
Drawing of a nasal cannula. A nasal cannula or an oral–nasal cannula consists of a flexible tube, usually with multiple short, open-ended branches for comfortable insertion into the nostrils and/or mouth, and may be used for the delivery of a gas (such as pure oxygen), a gas mixture (as, for example, during anesthesia), or to measure airflow ...
Heated humidified high-flow therapy, often simply called high flow therapy, is a type of respiratory support that delivers a flow of medical gas to a patient of up to 60 liters per minute and 100% oxygen through a large bore or high flow nasal cannula. Primarily studied in neonates, it has also been found effective in some adults to treat ...

A tracheal button is a rigid plastic cannula about 25 millimetres (0.98 in) in length that can be placed into the tracheostomy after removal of a tracheostomy tube to maintain patency of the lumen. History
•Thudichum's nasal speculum-do-; short blades ( uses: anterior rhinoscopy - to see the Little's area, ant-inferior part of nasal septum, anterior part of inferior and middle turbinate and meatus, as well as any pathological lesion in the area; also used in certain nasal operations ) •St. Clair Thompson's long bladed nasal speculum
Alternative techniques for airway management and delivery of oxygen, volatile anesthetics or other breathing gases include the laryngeal mask airway, i-gel, cuffed oropharyngeal airway, continuous positive airway pressure (CPAP mask), nasal BiPAP mask, simple face mask, and nasal cannula.
