Hello @healthsurrogate and welcome to Mayo Clinic Connect. I can see this is a challenging decision given his stable vital signs and recovery after unresponsiveness. It seems as though having a baseline and information to compare the progression to may be helpful and also provide some insight as well.

@farmerleebs may be able to share additional information as her mother has experienced an unresponsive episode. Other members who have also mentioned unresponsive episodes include @bethv, @chuckcallahan, @mshoggie, @judithanne.

I am curious what instructions you were given or advice his doctor suggested?
