Oxygen therapy for coronavirus infection can provoke bacterial pneumonia. This was announced by the chief researcher of the Research Institute of Disinfectology of Rospotrebnadzor, Corresponding Member of the Russian Academy of Sciences Elena Ilyina.
“Once you turn on any mandatory ventilation, and the oxygen supply is mandatory ventilation, you promote the exchange of bacterial flora between the upper and lower airways. There are always a lot of bacteria in the human mouth and nose. But the mucosa performs a barrier function, it absorbs microorganisms in a normal state. When using oxygen therapy, you willy-nilly carry bacteria from the nose and mouth into the trachea and lungs with the air flow.
All over the world, the list of bacteria that infect the lungs is approximately the same: Acinetobacter - various, mainly Acinetobacter baumannii, Pseudomonas aeruginosa, Klebsiella pneumoniae, staphylococci.
Most of these pathogens originated from soil bacteria, from which they have retained the ability to survive in common areas, on toilets, on sinks, and on other surfaces.
