Many people have been talking about the “hemoglobin hijacking” of COVID-19 but this is far from a certain theory and really only from a single computer simulation model.

It appears that hypoxic vasoconstriction is the most robust explanation at this time. This has led to some drawing parallels to high altitude pulmonary edema (HAPE).

Today we are joined by Dr. Rory Spiegel of EMNerd to discuss the ROX index which has been proposed as a means of predicting who might fail high flow nasal cannula, and has been proposed as a part of some pathways for COVID-19 respiratory management
