Thank You! I am grateful for all advice, knowledge, thoughts and I appreciate having this forum and that we can all help and talk to each other.

Update: He was released from the hospital today. My first post said esophagus rupture but it was esophagus tear, I think the situation is different than what I initially thought too. I am not worried if he gets angry with me over telling the truth. I told him to eat food and drink fluid or the next time that he would be home alone. (I feel horrible about this by the way. I didn't mean it and he knows that..he sort of laughed.)

The pulse (140 - 190) and the blood pressure dropping to 60 over 50 (for example) when he stands up are not heart problems per the Cardiologist. They are from Dehydration and Starvation (his words). I am sure that someone has experience with this but how can someone receive IV fluids for 4 days and still be dehydrated to the point of the BP and heart rate issues?

The lung X-Ray showed a spot on the upper left lung but the hospital says that spots are normal. The lymph node cancer was on the left as well. We have an Oncology appt Monday afternoon.

One of my many concerns is: If a hospital with an IV drip (the Dr said he was doubling the amount) can't keep him hydrated then how can we? If his heart rate is so high and his blood pressure drops so much due to dehydration then isn't it going to get worse now?

I do not know.
