Fraction of inspired oxygen (F I O 2), correctly denoted with a capital I, [1] is the molar or volumetric fraction of oxygen in the inhaled gas. Medical patients experiencing difficulty breathing are provided with oxygen-enriched air, which means a higher-than-atmospheric F I O 2.
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.

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 ...
Venturi masks are used to deliver a specified fraction of inspired oxygen (F I O 2).Many masks are color-coded and have a recommended oxygen flow specified on them. [5] When used with this oxygen flow, the mask should provide the specified F I O 2.
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 ...
The simple face mask can deliver higher flow rates than nasal cannula (6–10 liters per minute) for an FiO2 of 30- 60% oxygen. [1] Nasal cannula and simple face masks are described as low flow delivery systems. [2] [3] Unlike the non-rebreather and partial rebreather masks, the simple face mask lacks a reservoir bag.
A system which accumulates free-flow oxygen during resting and exhalation stages, (reservoir cannulas, partial rebreather masks and non-rebreather masks) makes a larger part of the oxygen available for inhalation, and it will be selectively inhaled during the initial part of inhalation, which reaches furthest into the lungs, and may also ...
{{convert|100|lb|kg}} → 100 pounds (45 kg) The unit-codes should be treated as case-sensitive: {{convert|100|Mm|mm}} → 100 megametres (1.0 × 10 11 mm) The output of {{convert}} can display multiple converted units, if further unit-codes are specified after the second unnamed parameter (without the pipe separator). Typical combination ...
