Real gases are non-ideal gases whose molecules occupy space and have interactions; consequently, they do not adhere to the ideal gas law. To understand the behaviour of real gases, the following must be taken into account: compressibility effects; variable specific heat capacity; van der Waals forces; non-equilibrium thermodynamic effects;
John Scott Haldane CH FRS [1] (/ ˈ h ɔː l d eɪ n /; 2 May 1860 – 14/15 March 1936) was a Scottish physician physiologist and philosopher famous for intrepid self-experimentation which led to many important discoveries about the human body and the nature of gases. [2]
Finally, the increased temperature of hypersonic flow mean that real gas effects become important. Research in hypersonics is therefore often called aerothermodynamics, rather than aerodynamics. [5] The introduction of real gas effects means that more variables are required to describe the full state of a gas.
Animals and humans naturally produce some hydrogen sulfide in their body; researchers have proposed that the gas is used to regulate metabolic activity and body temperature, which would explain the above findings. [18] Two recent studies cast doubt that the effect can be achieved in larger mammals.
Harris noticed that the consequences of high level altitude sickness on the human body mirrored COVID-19's dysfunctional impact on the lungs. His focus on nitric oxide comes from its role in being able to breathe in high altitudes. [100] [103] According to WCVB-TV, similar trials are being conducted at Tufts Medical Center. [104]
Barotrauma is physical damage to body tissues caused by a difference in pressure between a gas space inside, or in contact with, the body and the surrounding gas or liquid. [ 76 ] [ 33 ] The initial damage is usually due to over-stretching the tissues in tension or shear , either directly by an expansion of the gas in the closed space or by ...

The general effects of radon to the human body are caused by its radioactivity and consequent risk of radiation-induced cancer. Lung cancer is the only observed consequence of high concentration radon exposures; both human and animal studies indicate that the lung and respiratory system are the primary targets of radon daughter-induced toxicity ...
