ABSTRACT
COVID-19 infection typically causes pneumonia with bilateral changes on Chest radiograph. There is significant hypoxia and use of oxygen for patients admitted to hospital is standard. The use of Continuous Positive Airway Pressure (CPAP) in patients with COVID-19 has now become established as a common clinical practice based on recent experience. It is given as part of "best endeavours" treatment in the absence of sufficient evidence to guide best practice. The use of CPAP as a step up in clinical care is now common but has a poor evidence base. Using routinely collected data, the use of CPAP as a supportive non-invasive ventilatory treatment is described in 35 patients with COVID infection. Patients given early CPAP and in particular within 48 hours of admission, are shown to have a better outcome (a significant probability of lower mortality) than patients who received late CPAP (more than 48 hours after admission). Although the analysis is affected by a small sample size, the results have shown good evidence that supports the early use of CPAP in patients with COVID-19 infection.
