Clinical use of Heliox in Asthma and COPD
Monaldi Archives for Chest Disease, 2016 Heliox is a low density gas mixture of helium and oxygen commonly used in deep diving (> 6 ATM). This mixture has been also used for clinical purposes, particularly in the critical care setting.

Effects of Heliox in Stable COPD Patients at Rest and during Exercise
Pulmonary Medicine, 2012 Heliox has been administered to stable chronic obstructive pulmonary disease (COPD) patients at rest and during exercise on the assumption that this low density mixture would have reduced work of breathing, dynamic hyperinflation, and, consequently ...

Heliox for non-intubated acute asthma patients
Cochrane Database of Systematic Reviews, 2003 Helium and oxygen mixtures (heliox), have been used sporadically in respiratory medicine for decades. Their use in acute respiratory emergencies such as asthma has been the subject of considerable debate. Despite the lapse of more than 60 years since it was first proposed, the role of heliox in treating patients with severe acute asthma remains unclear.

EEG functional connectivity is sensitive for nitrogen narcosis at 608 kPa
Scientific Reports, 2022 Divers commonly breathe air, containing nitrogen. Nitrogen under hyperbaric conditions is a narcotic gas. In dives beyond a notional threshold of 30 m depth (405 kPa) this can cause cognitive impairment, culminating in accidents due to poor decision ...

Influence of Topological Edge States on the Properties of Al/Bi2Se3/Al Hybrid Josephson Devices [PDF]
, 2014 In superconductor-topological insulator-superconductor hybrid junctions, the barrier edge states are expected to be protected against backscattering, to generate unconventional proximity effects, and, possibly, to signal the presence of Majorana fermions.
