Low and middle-income countries (LMICs) urgently need cost-effective adaptive technologies to provide CPAP. The lead investigator has proved that a low cost, locally made bCPAP device is capable of reducing mortality in children, Its components are (a) an interface; nasal seal, (b) oxygen delivery piping, connectors and nasal cannula, (c) appropriately sized transparent plastic bottles (containing sterilized water). The device and its components are already being approved by the Directorate General of Drug Administration (DGDA), Government of the People's Republic of Bangladesh. Adapting this technology, if safe and scaled up, could possibly decrease the need for mechanical ventilation and subsequently averting deaths among adult COVID-19 patients.~The design of the nasal seal was comfortable and well tolerated by all the participants. Patients were told about some mild discomfort at higher delivered pressures (14 or 15 cm PEEP), consistent with pressurised nasal delivery by similar devices. No additional adverse events such as trauma/injury, erosion, bruise, bleeding, obstruction, breathlessness, pneumothorax, pneumomediastinum, abdominal distension during and after the trial were reported.~The safety phase has been initiated since 1st November 2020 and ended in April 2021. One patient withdrew from the study but none of them developed any adverse events.~The feasibility phase started at the end of September 2021.~Objectives:~To evaluate the barriers and operational challenges related to the introduction of adult bubble CPAP oxygen therapy~To evaluate the acceptability of introducing adult bubble CPAP in tertiary level hospitals of Bangladesh
