Heated humidified high-flow therapy, often simply called high flow therapy, is a medical treatment providing respiratory support by delivering a flow of oxygen of up to 60 liters per minute to a patient through a large-bore or high-flow nasal cannula. Primarily studied in neonates, it has also been found effective in some adults to treat ...
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.

1. Gas source: An oxygen blender connected to a source of oxygen and compressed air is used to supply an appropriate concentration of inspired oxygen . The humidified blended oxygen is then circulated through corrugated tubing. 2. Pressure generator: Pressure in the bubble CPAP system is created by placing the distal expiratory tubing in water.
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 ...
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.

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.
The alveolar oxygen partial pressure is lower than the atmospheric O 2 partial pressure for two reasons.. Firstly, as the air enters the lungs, it is humidified by the upper airway and thus the partial pressure of water vapour (47 mmHg) reduces the oxygen partial pressure to about 150 mmHg.
Heliox is a breathing gas mixture of helium (He) and oxygen (O 2).It is used as a medical treatment for patients with difficulty breathing because this mixture generates less resistance than atmospheric air when passing through the airways of the lungs, and thus requires less effort by a patient to breathe in and out of the lungs.
