“Is there a single case in the U.K. of a patient being induced in to a coma and put on a breathing maching, recovering and going home?”
Yes there is data from the Intensive Care National Audit and Research centre (ICNARC. If you want to read the whole paper you have to click and open the PDF. But basically it showed:
“Critical care unit outcomes have been received for only 1689 (of 3883) patients, of whom 871 patients have died and 818 have been discharged alive from critical care”. which means a survival rate of just under half 48%. I seem to remember similar figures from Italy. This article also discusses this subject.
