COVID-19 is a multifaceted infectious disease. The development of hypoxemic respiratory failure is not uncommon during the course of illness in some of them. The objectives of the present study were to assess the effect of the addition of a surgical face mask while delivering oxygen via nasal cannula in hypoxemic COVID-19 patients and highlight on the advantages and patient's comforts. We prospectively assessed 30 consecutive conscious and hypoxemic COVID-19 patients, requiring oxygen via nasal cannula. The mean PaO without and with surgical face mask were 52 (+9) and 83 (-12) mm Hg respectively in the cohort, and the elevation in oxygen saturation was statistically significant ( <0.001). The present results encourage the delivery of oxygen under the surgical face mask in symptomatic COVID-19 patients, as it improves oxygen saturation and prevents aerosol dispersion with no change in PaCO. The other advantages of this method are a reduction in the total requirement of oxygen per patient, better utilization of scarce resources, and lessening of the expenses incurred for oxygen.

新型冠状病毒肺炎(COVID-19)是一种多方面的传染病。在部分患者病程中发生低氧性呼吸衰竭并不少见。本研究的目的是评估在低氧性COVID-19患者经鼻导管吸氧时加用外科口罩的效果,并强调其优点和患者舒适度。我们前瞻性地评估了30例连续的意识清醒且低氧的COVID-19患者,这些患者需要经鼻导管吸氧。该队列中,不使用和使用外科口罩时的平均动脉血氧分压(PaO)分别为52(±9)和83(±12)mmHg,氧饱和度升高具有统计学意义(P<0.001)。目前的结果鼓励对有症状的COVID-19患者在外科口罩下吸氧,因为这可提高氧饱和度并防止气溶胶扩散,而动脉血二氧化碳分压(PaCO)无变化。该方法的其他优点包括降低每位患者的总吸氧需求量、更好地利用稀缺资源以及减少吸氧费用。
