Oxy-hydrogen gas: The rationale behind its use as a novel and sustainable treatment for COVID-19 and other respiratory diseases

Russell, Grace; Nenov, Alexander; Hancock, John

Abstract

Oxy-hydrogen gas (HHO) is a gaseous mixture of molecular hydrogen (H2) and molecular oxygen (O2) that is generated by the electrolysis of water and delivered in a 2:1 ratio (66% and 33%, respectively) through the use of non-invasive inhalation devices such as nasal cannulas or nebulisers. Although there is a paucity of scientific evidence supporting this new and emerging therapy, initial investigations indicate that oxy-hydrogen proffers cytoprotective qualities, typically by reducing oxidative stress and attenuating the inflammatory response. These aspects are particularly favourable when considering respiratory medicine as underlying inflammation is known to drive the pathological progress of numerous respiratory conditions, including asthma, chronic obstructive pulmonary disorder and, pertinently, COVID-19. Direct delivery to the lung parenchyma is also likely to increase the effectiveness of this emerging medical therapy. This narrative review aims to delineate how this particular combination of gases can affect cellular processes at the molecular level by focusing on the evolutionary requirement for both O2 and H2. Furthermore, the authors assess the current available data for the safety and efficacy of HHO in a clinical setting.
