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.
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.
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]

Bubble CPAP is a non-invasive ventilation strategy for newborns with infant respiratory distress syndrome (IRDS). It is one of the methods by which continuous positive airway pressure (CPAP) is delivered to a spontaneously breathing newborn to maintain lung volumes during expiration.
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 bag valve mask can be used without being attached to an oxygen tank to provide "room air" (21% oxygen) to the patient. However, manual resuscitator devices also can be connected to a separate bag reservoir, which can be filled with pure oxygen from a compressed oxygen source, thus increasing the amount of oxygen delivered to the patient to ...
The amount of oxygen available to the patient in mouth-to-mouth is around 16%. If this is done through a pocket mask with an oxygen flow, this increases to 40% oxygen. If either a bag valve mask or a mechanical ventilator is used with an oxygen supply, this rises to 99% oxygen. The greater the oxygen concentration, the more efficient the ...
