Simulation model of ventilation–perfusion mismatch

Warning! The intended audience of this article is medical professionals and students. I am not your doctor. This article is not medical advice. This article has not been subject to formal peer review. The model at https://yingtongli.me/blog/assets/posts/2026/vqmodel/ simulates a two-unit lung model where the two units may have different ventilation–perfusion (\(\dot{V}/\dot{Q}\)) ratios. The simulation demonstrates that, in the presence of \(\dot{V}/\dot{Q}\) mismatch, oxygenation is r...
