Coronavirus Pandemic Update 58: Testing; Causes of Hypoxemia in COVID-19 (V/Q vs Shunt vs Diffusion)

COVID-19 Update 58 with Roger Seheult, MD of https://www.MedCram.com

Two recent antibody testing studies in the United States may give insight into how widespread COVID-19 actually is – which may also mean the fatality rate is lower than initially thought – but there may be problems with the accuracy of using this data in a prediction model. Dr. Seheult also illustrates the key differences between different types of hypoxemia (low blood oxygen): V/Q mismatch, shunting, and diffusion abnormalities. COVID-19 infection may involve all three of these to varying degrees and MIGET (multiple inert gas elimination technique) studies may unlock some of the mystery.
