重症COVID-19患者的脉冲氧度 (SpO2) 和动脉血液气体 (SaO2) 不一致性较高. 然而,这种和度测量的差异主要是由患者组之间的种族差异驱动的.
科学领域:
- 关键护理医学 关键护理医学
- 肺部医学 肺部医学
- 传染性疾病 传染性疾病
背景情况:
- 对重症患者来说,精确的氧化监测至关重要.
- 脉冲氧计 (SpO2) 和动脉血液气体 (ABG) 分析 (SaO2) 是测量氧和度的标准方法.
- SpO2和SaO2之间的不一致会影响临床决策.
研究的目的:
- 为了比较COVID-19和没有COVID-19的重症患者中SpO2和SaO2之间的不一致率.
- 为了调查SpO2读数是否可能错误地分类COVID-19患者的低氧化症的严重程度.
- 为了确定混观察到的不一致的因素.
主要方法:
- 从成人ICU入院中对联SpO2和SaO2读数的回顾性分析 (2020年3月至5月).
- 主要结局:在COVID-19患者中的异调率 (SaO2-SpO2 下>4%) 与COVID-19患者中的异调率.
- 多变量回归通过pH值,温度,置换疗法和种族评估混.
主要成果:
- 与COVID-19患者 (16.7%) 相比,在COVID-19患者 (27.9%) 中观察到更高的和异常.
- COVID-19 (((+) 患者的SpO2错误分类他们的氧化状态的几率增加.
- 在控制自我识别种族后,COVID-19状态和不和之间的关联丢失了.
结论:
- 脉冲氧计显示,在重症COVID-19患者中,与ABG的不一致性更大.
- 研究群体之间的种族差异似乎是这种观察到的不一致的主要驱动因素.
- 需要进一步的研究来理解和解决 SpO2 精度的种族差异.
