Heliox may reduce all these effects, making it easier for the patient to breathe. [11] Heliox has also found utility in the weaning of patients off mechanical ventilation, and in the nebulization of inhalable drugs, particularly for the elderly. [12] Research has also indicated advantages in using helium–oxygen mixtures in delivery of ...
Nitrous oxide (dinitrogen oxide or dinitrogen monoxide), commonly known as laughing gas, nitrous, or factitious air, among others, [4] is a chemical compound, an oxide of nitrogen with the formula N
1840 illustration of a man inhaling nitrous oxide, and another experiencing its effects Until at least 1863, low availability of equipment to produce the gas, combined with low usage of the gas for medical purposes, meant it was a relatively rare phenomenon that mainly happened among students at medical universities.
Heliox may reduce all these effects, making it easier for the patient to breathe. [9] Heliox has also found utility in the weaning of patients off mechanical ventilation, and in the nebulization of inhalable drugs, particularly for the elderly.

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 ...
The drop of liquid at the bottom of the glass represents helium spontaneously escaping from the container over the side, to empty out of the container. The energy to drive this process is supplied by the potential energy of the falling helium. Helium liquifies when cooled below 4.2 K at atmospheric pressure.
Helium and nitrogen are non-toxic and can be breathed with no ill effects over short or long term when oxygen levels are sufficient, and present no health risk to third parties except asphyxiation. The danger lies in that they are undetectable by human senses, and the first warning of their presence in asphyxiant concentrations may be loss of ...
Trimix scuba cylinder label IMCA Trimix cylinder shoulder colour code alternative IMCA Trimix cylinder shoulder colour code. 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.
