无呼吸困难症状的缺氧

沉默缺氧(Silent hypoxia)又称隐形缺氧、快乐缺氧(happy hypoxia)[1][2],是没有出现呼吸困难症状的缺氧[3][4][5][需要可靠医学来源],目前已知是2019冠状病毒病的并发症之一[6][7],目前推测此疾病是因为COVID-19病毒影响肺内气道的血流以及肺中的血管,但没有严重到会呼吸困难的程度[8]。目前也怀疑沉默缺氧是因为肺部形成小血栓所造成[9][10][11][需要可靠医学来源]。目前发现COVID-19患者的呼吸率会渐增,接着慢慢进入沉默缺氧[12][需要可靠医学来源];而且也已证实同样活动后,COVID-19患者和非COVID-19肺炎病患相比,有较轻的呼吸困难症状[13];这种情况也是非典型肺炎[14][需要可靠医学来源]和高山症的症状[15]。

诊断
“六分钟行走测试”(six-minute walk test,6MWT)可以用来诊断沉默缺氧[16],主要是用正常的步伐走六分钟,监控身体的反应[17]。目前已证实,COVID-19患者和特发性肺纤维化的非COVID-19患者比较,在六分钟行走测试后,比较会有运动引发的无症状缺氧[18]。此症状也可以在医院外用脉搏血氧浓度仪侦测[19][20]。
