Prediction of Extubation Failure in COVID-19

BACKGROUND: S-pO2/F-IO2 may be a reliable noninvasive alternative to the P-aO2/F-IO2 index. Furthermore, the ROX index (ie, the ratio of S-pO2/F-IO2 to breathing frequency) has been validated to predict high-flow nasal cannula failure in subjects under spontaneous breathing. However, these indices h...
