COVID-19 patients normally experience mild cold-like symptoms that progress from the early viral response phase through the lung phase to the hyper-inflammation phase. Acute respiratory distress syndrome (ARDS) characterizes the most critical stage of the illness with progressive respiratory failure. Hypoxemia is the most dangerous and challenging problem. We suggest an inductive study approach to postulate a hypothesis and synthesis of supporting evidence as a trial to resolve hypoxia in patients with COVID-19 by increasing the volume of fetal hemoglobin which has a high affinity for oxygen using methods for hypothesis related research evidence synthesis. We recommend involving umbilical cord fetal blood transfusion or the use of hydroxyl urea as a clinical trial on COVID-19 patients and also for all other types of ARDS to determine its efficacy in correction of hypoxemia, controlling progression of the disease, and increasing survival rate.

增加胎儿血红蛋白作为改善缺氧和挽救 COVID-19 患者最后一口气的可能关键：“假设一个假设”

COVID-19 患者通常会出现轻微的类似感冒的症状，这些症状会从早期病毒反应阶段通过肺部阶段发展到过度炎症阶段。急性呼吸窘迫综合征 (ARDS) 是疾病最关键的阶段，伴有进行性呼吸衰竭。低氧血症是最危险和最具挑战性的问题。我们建议采用归纳研究方法来假设假设并合成支持证据，以此作为通过增加对氧气具有高亲和力的胎儿血红蛋白的体积来解决 COVID-19 患者缺氧的试验，使用假设相关的研究证据合成方法。
