Ok, While he was on dialysis, the nurses decided to start him tonight on the meds that will lower the potassium, rather then waiting later in the week to see the doctor, or having him admitted to ER. They're hoping that this will lower his potassium level down.
A few months ago, a similar situation happened, and that time the doctor's didn't know how he managed to come out of it. This time, I think it was caught much earlier.
Anyway, he still needs prayers. And thanks everyone for praying.
