Sorry that I have been away for so long... But, my father was admitted to hospital emergency on Friday morning at 2 am. Vomiting was the issue at first, but now with one lung found full of fluid, and when drained filled up full again, things have become a surprising uphill battle for my father. At 90 plus age, there is not much the hospital will do if it is an operational cure. It "could" be cancer, or COPD heart problems. We drained the lung once, to see if it would remain drained. It filled up again really quickly, causing doctors to give a very negative prognosis. They said it was not pneumonia, to fill up that quickly again. This was 3 doctors giving a poor outlook on his future outcome, and could live between 3 days to a month, plus or minus. 60 % oxygen was the first value given to me Friday morning. When the lung drained, we achieved 97 % Oxygen. Then, though the weekend, we had a high pulse but 80 to 70 % oxygen. Monday and Tuesday, I thought death was ring...
