CPAP and High Flow nasal cannula oxygen are two established modalities for non-invasive respiratory support . In COVID pandemic era both CPAP and HFNO were widely used in the ward for the treatment of COVID-19 induced acute hypoxemic respiratory failure in order to prevent progression to intubation. Head to head comparison between the two modalities mentioned for the treatment of severe hypoxemic respiratory failure is not available neither in COVID pneumonia or Community acquired pneumonia (CAP).
the study compares two non-invasive respiratory support modalities ie CPAP and High Flow nasal cannula oxygen for the treatment of severe hypoxemic respiratory failure attributed to Community acquired Pneumonia.
