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.
However, if the supplied breathing gas is free of carbon dioxide, the blood carbon dioxide levels will remain low while breathing occurs, and there will be no distress or urge to increase breathing rate, as the sensitivity in normal people to blood oxygen level as a breathing stimulus is very low.

breathing mask A breathing mask is a facepiece that covers the mouth and nose, and optionally other parts of the face or head, to constrain and direct the flow of breathing gas as part of a breathing apparatus. bubble CPAP Bubble CPAP is a non-invasive ventilation apparatus for newborns with infant respiratory distress syndrome (IRDS).
A breathing gas is a mixture of gaseous chemical elements and compounds used for respiration. Air is the most common and only natural breathing gas. Other mixtures of gases, or pure oxygen, are also used in breathing equipment and enclosed habitats such as scuba equipment, surface supplied diving equipment, recompression chambers, high-altitude mountaineering, high-flying aircraft, submarines ...
Polish Au-2 escape respirator. Escape breathing apparatus, also called escape respirators, escape sets, self-rescuer masks, emergency life saving apparatus (ELSA), emergency escape breathing devices (EEBD), and Respiratory Protective Smoke Escape Devices (RPED), [1] [2] are portable breathing apparatus that provide the wearer with respiratory protection for a limited period, intended for ...
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.
Berberine can upset your gastrointestinal system, causing symptoms like: nausea, diarrhea, constipation, gas and abdominal pain, Simmons says. It’s also possible that taking berberine can ...
An open circuit SCBA typically has three main components: a high-pressure gas storage cylinder, (e.g., 2,216 to 5,500 psi (15,280 to 37,920 kPa), about 150 to 374 atmospheres), a pressure regulator, and a respiratory interface, which may be a mouthpiece, half mask or full-face mask, assembled and mounted on a framed carrying harness.
