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 ...
Portable oxygen concentrator used with bottle humidifier. POCs operate on the same principle as a home concentrator, pressure swing adsorption. [6] The basic set up of a POC is a miniaturized air compressor, a cylinder filled containing the sieve, a pressure equalizing reservoir and valves and tubes.
An oxygen concentrator takes in air and removes nitrogen from it, leaving an oxygen-enriched gas for use by people requiring medical oxygen due to low oxygen levels in their blood. [4] Oxygen concentrators provide an economical source of oxygen in industrial processes, where they are also known as oxygen gas generators or oxygen generation plants.
Although the humidifying capacity of a bubble respiratory gas humidifier is rather low, it may be improved by increasing the water temperature. A bubble bottle is mostly used in oxygen therapy with high flow rates via a mask, nasopharyngeal catheter, or nasal cannula in order to prevent drying of the mucous membranes in the nose and mouth.

There are different aviation oxygen systems and delivery methods available depending on the specific application. The oxygen source may be chemical oxygen generators, high pressure portable gaseous oxygen storage systems (gas cylinders), on-board oxygen generating systems (oxygen concentrators), or liquid oxygen systems. [4]
The total flow of gas (oxygen plus the entrained air) will be greater than the patient's peak inspiratory flow so the delivered F I O 2 is independent of their respiratory pattern. [ 5 ] A controlled F I O 2 is particularly important for patients whose ventilation is dependent on hypoxic drive , [ 5 ] as may be seen in patients with chronic ...
