Prone positioning is known to improve the PaO2/FiO2 ratio and reduce mortality in patients with ARDS managed in the critical care setting. Therefore, it is incorporated into regular clinical practice of managing patients with ARDS in critical care and is being used as such in the COVID-19 outbreak. Given that prone positioning is recommended by the Intensive Care Society in non-ventilated patients with COVID-19, there is an urgent need to better understand the physiological effects of prone positioning in such cases. Furthermore, the translation and applicability of such a low-cost non-invasive intervention in a wider group of patients with pneumonia not specific to covid-19 infection, is an important consideration that merits investigation. This single-centred observational study conducted at Cambridge University Hospitals NHS Foundation Trust aims to improve understanding of physiological effects of prone positioning in non-ventilated patients with COVID-19 and a control group of patients with non-COVID-19 related pneumonia. The study also aims to incorporate a small subset of patients, with an approximately even spread of COVID-19 and non-COVID cases, which allows for an additional exploratory descriptive report on prone positioning over a 24-hour period. This study proposes that prone positioning improves oxygenation in non-ventilated patients with pneumonia (COVID-19 related or not) requiring supplemental oxygen managed outside of the critical care setting.

Coronavirus infection, also known as COVID-19, has become a global pandemic with over 3 million cases and 250,000 deaths worldwide. Coronaviruses (CoV) belong to a family of viruses that predominately infect mammals and birds, affecting their lungs, intestinal tract, liver and nervous systems. Prior to the discovery of the current novel coronavirus strain (SARS-CoV-2), there were six different strains that are known to infect humans, which includes the virus that caused the severe acute respiratory syndrome (SARS) pandemic in 2002. In humans, the majority of severe illness from SARs and COVID-19 is due to inflammation of the lungs and pneumonia. Pregnancy poses a significantly increased risk of viral pneumonia and during SARS more pregnant women required intensive care and breathing support, and the proportion of deaths was higher when compared to non-pregnant adults. Furthermore, kidney failure and development of abnormal blood clotting disorders, which occurs during severe infection, is more common in pregnancy and the associated changes in blood vessels extend to the placentas of infected pregnant women, thus potentially affecting the fetus. This makes pregnant women affected by the virus at high risk of developing severe complications. Fortunately, there have been a number of biomarkers identified that are associated with illness severity. These include, specialised white blood cells, blood clotting cells and constituents, as well as other measures of heart and kidney function. We propose that these biomarkers are important correlates of clinical disease severity and prognosis in pregnant and postnatal women. This knowledge has the potential to help clinicians during this pandemic to better manage and care for their patients.
