Many COVID-19 patients are presenting with atypical clinical features. Happy hypoxemia with almost normal breathing, anosmia in the absence of rhinitis or nasal obstruction, and ageusia are some of the reported atypical clinical findings. Based on the clinical manifestations of the disease, we are proposing a new hypothesis that SARS-CoV-2 mediated inflammation of the nucleus tractus solitarius may be the reason for happy hypoxemia in COVID-19 patients.

COVID-19-A神经假说中的快乐低氧血症。

许多COVID-19患者表现出非典型的临床特征。快乐的低氧血症，几乎可以正常呼吸，在没有鼻炎或鼻塞的情况下会出现失眠，以及听觉异常是一些非典型的临床发现。基于该疾病的临床表现，我们提出了一个新的假设，即SARS-CoV-2介导的孤索核炎可能是COVID-19患者低氧血症的原因。
