Welcome to the roller coaster ride. Dad had another rough night last night. He is running a fever again and had problems with low blood pressure, so they had to infuse him with a liter of saline solution and they won't be removing excess fluids from his body via dialysis today. He also had problems with poor blood oxygen saturation again, so they turned the FiO2 on his ventilator up to 100%. Hopefully this will be very temporary. This morning I will be attempting to contact Dr. Shelley, the Head of Highland's infectious diseases unit, to get an update on the status of diagnostics and lab tests to determine what is wrong with Dad.
