Dad's blood volume was down 25-26% and he was anemic on top of that. Last Wednesday and Friday each he had a 300ml blood pack (equivalent to a few pints of whole blood).
This weekend he was having trouble breathing, so on his doctor's recommendation, he went to the hospital. They confirmed that he has viral pneumonia. He has had nebulizer treatments (vapor inhale) and it's helped his breathing, and even cleared up some of his several-year-long congestion problems. They think he'll be ok in a few more days.
They're keeping him for a week or two for diet, anemia and other blood tests, and for his foot which has gotten a little worse.
Pleasant Ridge Chirch of Christ Arlington Workgroup has shown up and put up trim and painted his house for him (15 girls, 8 guys).
Once he gets out, he plans to have a wider door put in the front with his boat tennant's help.
He seems to be in good spirits.
