Since sedation is required for using a vetilator and the mortality is 85% anyway
perhaps they should be used only when success is likely.  CPAP BiPAP do not require
sedation so if they fail the patient will not be so likely to die.  After the 1995
Chicago heat wave the mortality of the aged was lower than normal the next year,
so there was little net change.  So not everyone may not need heroic efforts to 
survive.  The grassroots efforts should be directed toward sewing face masks with 
nonwoven inserts, makeing face shield head bands with 3d printing, and converting 
shipping containers so that the Batttelle design can be implemented by every 
welding shop.  Drycleaners and anyone with a vacuum desiccator and a supply of 
hydrogen peroxide or other appropriate gas should be able to decomtaminate 
disposable PPE money and other articles in short supply.
