Very low blood pressure was the first sign something was wrong. It's still dangerously low and his blood is not prefusing to his organs properly.

Lactic acid is building up in his system. This also shows his body is not oxygenating properly. It's common in people with sepsis and very low blood pressure.

The levels of potassium in his blood are increasing. This is because his kidneys have stopped functioning.

There is a hematoma (basically a black and blue mark) on his spleen where a blood vessel must have burst. They are giving him hemoglobin (plasma) and taken him off the blood thinners to treat this. It seems to be helping some, but it's not enough given everything else that's going on.

The nurse said this began last night when he did not tolerate the evening 'exercise' of being off the ventilator, but they thought perhaps he was tired, he had done very well in the morning.

He had no fever then, still no fever now. The cultures they had taken a few days ago didn't show any signs of infection. He was on 3 kinds of antibiotics then, today they changed the antibiotics to different, broad spectrum antibiotics.

I'm not ready for this, but I'm not sure he'll make it through the night.
