Oxygen therapy using Bain’s Circuit as an alternate option for moderate COVID-19 patients in resource-limited set-ups

Abstract

Dear Editor, Coronavirus disease of 2019 (COVID- 19) has been slowly engulfing society since December 2019. Many parts of the world are facing the second and third waves of the pandemic. The virus is rapidly getting mutated, posing a significant challenge. Oxygen therapy is required in most symptomatic patients, and most mild-to-moderate cases are managed by supportive therapy using a face mask. Non-Rebreathing Facemask (NRBM) is frequently used as it can provide a higher fraction of inspired Oxygen (FiO2). However, it cannot deliver a Positive End- Expiratory Pressure (PEEP). Even the positive pressure generated inside the mask is nearly zero.
