Sayan I, Altınay M, Çınar AS, et al. - Owing to the high rates of mortality in intubated patients in Covid-19 pneumonia, a rise in non-invasive methods of respiratory support occurred. Researchers here examine how HFNC (High Flow Nasal Cannula) application affected intubation requirement, intensive care length of stay, and short-term mortality in patients with COVID-19 pneumonia. This study was performed including 43 patients who received oxygen by reservoir mask or HFNC therapy in the intensive care units due to COVID-19 pneumonia. Findings revealed administration of HFNC in respiratory failure secondary to COVID-19 pneumonia to be correlated with an improvement in oxygenation as well as a decrease in the need for intubation and mortality. No change in the length of stay in intensive care was observed in correlation with HFNC.
