COVID-19 causes non-specific pneumonia, which has become a new cause of hypoxia, leading to the death of many patients. Today, there are no effective drugs that provide an urgent increase in blood oxygenation. Therefore, it is urgently necessary to develop drugs to increase blood oxygenation in order to save the lives of patients with the new coronavirus infection. Since hypoxia develops in this disease due to the blockage of respiratory tract with viscous mucus and sputum, an appropriate experimental model is needed for screening and finding new drugs. However this model is yet missing. Therefore, the development of an experimental model of respiratory obstruction by sputum with traces of blood can accelerate the discovery of drugs that eliminate hypoxia and prevent the death of patients with nonspecific pneumonia complicated by respiratory obstruction. The purpose of this letter was to present a model for evaluating the biological activity of drugs, which can become a new vector for the development of effective ways to increase blood oxygenation across pulmonary and save the lives of patients with severe atypical pneumonia complicated by respiratory obstruction in COVID-19.
It has been shown that the new coronavirus infection is life-threatening for patients not because of the COVID-19 virus, but because of the complications it causes. The most dangerous complication of this disease is the airway obstruction syndrome, which occurs with atypical pneumonia. Blockage of the airways occurs due to the accumulation of excessively large amounts of mucus and pus in them and swelling of the lung tissue, so ventilation of the lungs with air becomes almost impossible. The sad outcome of respiratory obstruction is hypoxia and hypoxic brain damage. Under these conditions, extracorporeal membrane oxygenation remains the only known way to increase blood oxygenation. However, in 2021, it was shown that intra-pulmonary administration of a warm alkaline solution of hydrogen peroxide immediately turns mucus and pus into oxygen foam and increases blood oxygen saturation. The proposed technology is a new variant of emergency blood oxygenation in severe suffocation caused by blockage of the respiratory tract with mucus, pus and blood.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
