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]
Another type of device is a humidified high flow nasal cannula which enables flows exceeding a person's peak inspiratory flow demand to be delivered via nasal cannula, thus providing F I O 2 of up to 100% because there is no entrainment of room air. [73] This also allows the person to continue to talk, eat, and drink while still receiving ...
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 ...
•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
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 into and out of the nose and ...
In medicine, a nasopharyngeal airway (NPA), nasal trumpet (because of its flared end), or nose hose, is a type of airway adjunct, a tube that is designed to be inserted through the nasal passage down into the posterior pharynx to secure an open airway. It was introduced by Hans Karl Wendl in 1958. [1]
Antral lavage is a largely obsolete [citation needed] surgical procedure in which a cannula is inserted into the maxillary sinus via the inferior meatus to allow irrigation and drainage of the sinus. [1] It is also called proof puncture, as the presence of an infection can be proven during the procedure.
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.
