Nana,
I agree with M.G.-call the paramedics,
they do have the equipment. I had to
call for my father one time years ago,
and they hooked him up right then and
there. Do this for you, and if there
is something wrong-they will take him
to the hospital-even better for you, and
maybe he will get the treatment that he
needs.
My prayers are with you.
Hugs,
