Description

Alnababteh et al reported a model for predicting the need for invasive mechanical ventilation in a patient with COVID-19. This can help to identify a patient who may benefit from more aggressive management. The authors are from Medstar Washington Hospital Center in Washington, D.C.


Patient selection: COVID-19

Parameters:

(1) SpO2 to FIO2 ratio (with FIO2 in percent from 21 to 100)

(2) heart rate in beats per minute

(3) serum troponin I (positive or negative)
