The CircumVent Project: A CPAP/O2 Helmet Solution for Non-Invasive Ventilation Using an Implementation Research Framework

The purpose of the CircumVent Project is to evaluate the feasibility, adaptability and acceptability of a CPAP/O2 helmet solution for non-invasive ventilation among patients with COVID-19 and health workers in eight COVID-19 treatment and isolation centers in Nigeria.

Acute respiratory failure, a major cause of death in COVID-19, is managed with high-flow oxygen therapy via invasive mechanical ventilation. In resource-limited settings like Nigeria the shortage of ventilators and oxygen supply make this option challenging. Evidence-based non-invasive alternatives to mechanical ventilation such as the use of continuous positive airway pressure (CPAP) devices exist, but there have been concerns that non-invasive ventilation may expose healthcare workers to infection from aerosolized dispersion of SARS-CoV-2. The investigators propose to evaluate the feasibility, adaptability and acceptability of a CPAP/O2 helmet solution for non-invasive ventilation among patients with COVID-19 and health workers in eight COVID-19 treatment and isolation centers in Nigeria. The study will occur in 4 stages: 1) Convene a Steering Committee of key stakeholders and recruit implementation sites; 2) Use the integrated Promoting Action on Research Implementation in Health Services (i-PARiHS) framework to guide a needs assessment of treatment centers' capacity to use high-flow oxygen therapy to treat COVID-19 patients, and utilize the findings to develop an implementation strategy for use of CPAP/ O2 helmet solution; 3) Build infrastructure to support training and data monitoring processes and to develop implementation protocols to evaluate the adaptability of the strategy for the use of the CPAP/O2 helmet; and 4) Train health workers, distribute a CPAP/O2 helmet solution for non-invasive ventilation, pilot test the implementation strategy, and assess feasibility of its use and acceptability that includes monitoring altered risk of SARS-CoV-2 infection among healthcare workers.
