Using the prone position could help to combat the development of fast hypoxia in some patients with COVID‐19	2020-06-17		.txt	text/plain	2000	110	43	Since ventilation distribution does not change between supine and prone positions, the higher expression of nitric oxide in dorsal lung vessels than in ventral vessels is likely to be the most important mechanism behind enhanced oxygenation in the prone position. • Gravity is only one variable responsible for ventilation/ perfusion matching and is executed in concert with lung structure and fractal geometry, gas distribution and regulation of lung vascular tone. Based on this review, it is concluded that gravity is one of the variables responsible for V/Q matching, but in concert with lung structure and fractal geometry, gas distribution and regulation of lung vascular tone. In view of the unchanged ventilation distribution of prone and supine, it currently seems that the most important mechanism is different regulation of lung vascularity in dorsal and ventral lung regions, due to expression of the potent vasodilator NO.	./cache/cord-342150-dadc8whz.txt	./txt/cord-342150-dadc8whz.txt
