Euthanasia. A suicide bag, also known as an exit bag or hood, [1][2] is part of a euthanasia device consisting of a large plastic bag with a drawcord used to die by suicide through inert gas asphyxiation. It is usually used in conjunction with a flow of an inert gas that is lighter or less dense than air, like helium or nitrogen.
Heliox. 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. It ...
Asphyxiant gas. An asphyxiant gas, also known as a simple asphyxiant, is a nontoxic or minimally toxic gas which reduces or displaces the normal oxygen concentration in breathing air. Breathing of oxygen-depleted air can lead to death by asphyxiation (suffocation). Because asphyxiant gases are relatively inert and odorless, their presence in ...
Safer use can involve inhalation while seated to decrease risks of injury by falling. Inhalation directly from a tank poses serious health risks, as it can cause frostbite since the gas is very cold when released. For those reasons, most recreational users will discharge the gas into a balloon or whipped cream dispenser before inhaling. [6]
Helium. hexagonal close-packed (hcp) Helium (from Greek: ἥλιος, romanized: helios, lit. 'sun') is a chemical element; it has symbol He and atomic number 2. It is a colorless, odorless, non-toxic, inert, monatomic gas and the first in the noble gas group in the periodic table.
High-pressure nervous syndrome. High-pressure nervous syndrome (HPNS – also known as high-pressure neurological syndrome) is a neurological and physiological diving disorder which can result when a diver descends below about 500 feet (150 m) using a breathing gas containing helium. The effects experienced, and the severity of those effects ...
The inhalation from larger helium balloons has been reportedly fatal. [26] A fatal fall from a tree occurred after the inhalation of helium from a toy balloon, which caused the person to become either unconscious or lightheaded. [27] In 2015, a technician at a health spa was asphyxiated while conducting unsupervised cryotherapy using nitrogen ...
Trimix (breathing gas) Trimix is a breathing gas consisting of oxygen, helium and nitrogen and is used in deep commercial diving, during the deep phase of dives carried out using technical diving techniques, [1][2] and in advanced recreational diving. [3][4] The helium is included as a substitute for some of the nitrogen, to reduce the narcotic ...
