Within half an hour the iron in the electrode is "plated off" (in effect, dissolved), and much of it goes into the electrically induced blood clot that seals the artery...

In those diseases, the trouble is in the air passages or the air spaces of the lungs themselves. With clotting obstructions, the trouble originates in the blood vessels. But in the long run, it has just as serious effects on breathing...
