I stitched together an image of graphs over time comparing France and UK cases, deaths, ICU admissions and hospital admissions using those from ourworldindata.org. It’s not the best image as I had to squash things a bit to get it to fit in one web page for ease of comparison. A french ICU doc/nurse might be able to explain things to us if we had one.
I think not all those French ICU admissions are ventilated and that perhaps patients cared for in non ICU settings in UK might be cared for in ICU in a French setting. I’m not suggesting any difference in quality of care just that things are organised differently in different health care systems.
