In order to treat edema...There are at least three techniques to

1. Diuretic, such as lasix;
2. Increase osmolarity by infusing albumin or fresh blood;
3. PUF when ever lasix does not work well.

This patient has wet lung and lower limb edema for weeks, and it diminished too slow. If a lung infection happens, it might kill the patient. That was why Dr. Eagen carried out an aggressive treatment by employing lasix, infusion of albumin and transfusion of fresh blood, and PUF as well. So far, until this doctor came in, the fat guy started a real improvement.
