My father has been in the ICU for 6 days since he was in a very bad accident. His hemoglobin count has been 3-4. They have been giving him EPO and albumin, as much as they can. Right now his SvO2 is averaging in the 60's his HR is 110, his CMap is above 75. He is 59. How long can his heart maintain this? Have there been any similar cases?
