An infant placed under an oxygen tent An oxygen tent consists of a canopy placed over the head and shoulders, or over the entire body of a patient to provide oxygen at a higher level than normal. Some devices cover only a part of the face.
Oxygen supply system that provides pure oxygen on demand at a pressure slightly above ambient, as is necessary for cabin altitudes above 34,000 feet. A type of positive pressure breathing system used with a pressure suit. [2] pressure regulated volume control Mechanical ventilation which is a combination of pressure and volume controlled ...
A resuscitator is a device using positive pressure to inflate the lungs of an unconscious person who is not breathing, in order to keep them oxygenated and alive. [citation needed] There are three basic types: a manual version (also known as a bag valve mask) consisting of a mask and a large hand-squeezed plastic bulb using ambient air, or with supplemental oxygen from a high-pressure tank.

Bag valve mask. Part 1 is the flexible mask to seal over the patients face, part 2 has a filter and valve to prevent backflow into the bag (prevents patient deprivation and bag contamination) and part 3 is the soft bag element which is squeezed to expel air to the patient
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]
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 ...
Oxygen rebreathers can also use less reactive scrubber absorbent which only removes carbon dioxide, but must then have an alternative supply of oxygen, usually compressed gas from a high pressure cylinder. Submarine escape sets had a mouthpiece, so the user had to also wear a noseclip to prevent breathing water through the nose. The endurance ...
