Bain H: Innovative Modification of Bain Circuit for the Resuscitation and Transportation of Patients With Coronavirus Disease 2019

Abstract

Bain H circuit is an innovatively modified breathing circuit designed for the transportation and resuscitation of patients with coronavirus disease . For this circuit, the Heidbrink valve was replaced with a 15F inlet and 15M/22F outlet adjustable pressure-limiting (APL) valve, and a high-efficiency particulate air filter was placed over the APL outlet valve. The circuit is designed to filter the novel coronavirus without any increase in dead space or resistance. All benefits of the conventional Bain circuit were retained. Besides its use in dedicated COVID-19 areas, this circuit can be used in other emergency units of the hospital. (A&A Practice. 2021;15:e01530.) GLOSSARY APL = adjustable pressure-limiting; COVID-19 = coronavirus disease 2019; HEPA = high-efficiency particulate air; HME = heat and moisture exchanger; ICU = XXX; RT-PCR = reverse transcription polymerase chain reaction; SARS-CoV-2 = severe acute respiratory syndrome coronavirus 2; WHO = World Health Organization
