Oxygen Administration under Surgical Face Mask in COVID-19 Patients: A Game Changer

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(2) 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 (p <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(2). 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.
