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]
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 ...
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 ...
Oxygen masks may cover only the nose and mouth (oral nasal mask) or the entire face (full-face mask). They may be made of plastic , silicone , or rubber . In certain circumstances, oxygen may be delivered via a nasal cannula instead of a mask.
One shortcoming of measuring pulse oximetry alone is that administration of supplemental oxygen (ie. via nasal cannula) can delay desaturation in a patient if they stopped breathing, therefore delaying medical intervention. Capnography provides a rapid way to directly assess ventilation status and indirectly assess cardiac function.
Oxygen can be delivered to spontaneously breathing patients via nasal cannula, face mask, artificial airway, or by built-in breathing system demand mask or oxygen hood in a hyperbaric chamber. [49] [50] Delivery may be by continuous flow, by bag reservoir mask, on demand, or on pulse demand. [43]

•St. Clair Thompson's long bladed nasal speculum-do-; long blades ( uses: in operations such as Submucous Resection of the nasal septum) •Killian's long bladed nasal speculum-do-; long blades and with handles; used more operations like SMR & Septoplasty. ( advantage: blade can be adjusted and fixed with screws, to avoid strain due to holding )
