Inhaled Nitric Oxide Tied to Improved P/F Ratio in COVID-19 With ARDS

 Inhaled nitric oxide (iNO) is associated with improvement in the mean partial pressure of oxygen (PaO₂)/fraction of inspired oxygen (FiO₂) ratio (P/F ratio) among patients hospitalized with COVID-19 and mild-to-moderate acute respiratory distress syndrome (ARDS), according to a study published online April 11 in Drugs in Context.
