Home Management of Patients with Moderate or Severe Respiratory Failure Secondary to COVID-19, Using Remote Monitoring and Oxygen with or without HFNC

Background: Home treatment of patients affected by COVID-19 is still a matter of daily debate. During the clinical evolution of the disease, there are high risks of lung failure, which requires oxygen therapy. Here, we report our clinical experience with at-home treatment using high-flow nasal cannula in non-hospitalised patients with confirmed COVID-19. Patients and methods: In this study, 18 patients with moderate-to-severe respiratory failure secondary to COVID-19 were monitored at home daily for temperature and SpO2 measurements. Other parameters such as saturation of peripheral oxygen (SpO2), SpO2/FiO2 (fraction of inspired oxygen), temperature, and lung performance were monitored periodically. Depending on oxygen requirements, the patients also received either standard oxygen via a face mask or, if higher FiO2 required, high-flow nasal cannula (HFNC). Results: All 18 patients had favourable outcomes and recovered from COVID-19. No death was recorded in this group. Conclusion: Our clinical experience proves that high-flow nasal cannula oxygen therapy may be considered for at-home treatment of COVID-19 patients with moderate lung failure. This could be useful for further treatment during the pandemic and may also be considered in future epidemics.
