Oxygen supplementation is required for approximately 14% of the patients diagnosed of having COVID-19 infection. Despite the use of conventional oxygen therapy, 5% among these require treatment in the intensive care unit (ICU). Here, we are describing a situation in which oxygen therapy was delivered to the patients by making an assembly of oxygen tubing, three-way stopcock, and high-flow nasal cannula (HFNC) present in the hospital setting following the malfunction of air blender of HFNC machine (Fig. 1). This assembly might be useful as rescue oxygen therapy during a malfunction of HFNC machine and in resource-limited settings where HFNC machine is not available. The mechanisms of action could be (1) washout of anatomic dead space due to medium oxygen flow, (2) improved gas mixing in large airways, and (3) increased oxygen concentration inside the conducting airway.

约14%被诊断为感染新冠病毒的患者需要吸氧。尽管采用了传统氧疗，但其中5%的患者需要在重症监护病房（ICU）接受治疗。在此，我们描述一种情况，即医院环境中在高流量鼻导管（HFNC）机器的空气混合器发生故障后，通过组装氧气管、三通旋塞和高流量鼻导管为患者提供氧疗（图1）。在HFNC机器发生故障期间以及在没有HFNC机器的资源有限的环境中，这种组装方式作为急救氧疗可能会有用。其作用机制可能为：（1）中等氧流量冲洗解剖无效腔；（2）改善大气道内的气体混合；（3）增加传导气道内的氧浓度。 库马尔A、库马尔A、库马尔N、库马尔A、辛格V、库马尔S等。将故障的高流量鼻导管重新包装作为急救氧疗：新冠疫情危机中的一项创新。《印度重症监护医学杂志》2021年；25（8）：948 - 949。
