Caregiver training could have saved his life

I believe that anyone that is a family caregiver, should be properly trained. My husband was diagnosed with stage 4 cancer and after fighting for two years, he received a bone marrow transplant. He was put up in a hotel suite for recovery. Well, on Easter when I walked into the hotel suite, I noticed that my husband was sweating quite a bit. Had me and his brother had the proper medical training we would have known that his blood pressure was high and that he was on the break of having a heart attack way before he had one. I believe that the proper training could have saved his life. Now me and my brother-in-law will always wonder if we could have done more.
