Low Dose Anti-inflammatory Radiotherapy for the Treatment of Pneumonia by COVID-19

Summary

Low radiation doses produce anti-inflammatory effects, which may be useful in the treatment of respiratory complications of COVID-19. This type of treatment is non-invasive and therefore, a priori, it can be used in all types of patients. Main objective: To evaluate the efficacy of low-dose lung irradiation as an adjunctive treatment in interstitial pneumonia in patients with COVID-19 by improving the PAFI O2 by 20% measured 48h after treatment with respect to the pre baseline measurement. -irradiation.
