Back to ICU with neutropenic spesis

Yesterday everything started going wrong, it started in the morning that he was feeling tired and weak, he then collapsed in the passage and then his temperature started climbing to 40. They admitted him to emergency and then put him into Intensive Care as his blood pressure had dropped to 80/20. They pumped him with lots of adrenaline to get it up again which was successful at 9pm last night. He is now getting lots of IV antibiotics to get the infection under control. His blood counts are still very low so he has no resistance to any infection, his white cell count is only 0.1. They call it neutropenic sepsis, they now need to find the source of the infection.
