Help visiting my father in the ICU

Recently, my brother and I have had trouble getting a hold of my father in Georgia. Today, piedmont hospital ICU center contacted us letting us know that they have been trying to get a hold of us for a few days now. He came down with severe pneumonia and a few days ago he was in really bad shape, his right lung has collapsed and his kidneys failed. He is a fighter and is doing better, he is a little responsive however still sedated and the hospital just received my brother's and my consent to undergo thoracic surgery. They have to open up his chest cavity to get all of the fluid and goo out of his lungs and repair his right lung. They say he has a high chance of success as long as he undergoes surgery. My brother and I just moved to Colorado a few months ago and could really use some help flying to Georgia to be there with him. Please, anything will help and anything extra will go towards assisting with medical bills.
