The Ebola patient fighting for his life in a Dallas hospital is on a ventilator and a kidney dialysis machine to help stabilize his health, the hospital said on Tuesday.

Liberian national Thomas Eric Duncan, the first person diagnosed with the deadly virus on U.S. soil, has also been given the experimental medication brincidofovir. A hospital in Nebraska said it is using the same drug to treat an American journalist who was airlifted from Liberia and arrived Monday.

Texas Health Presbyterian Hospital said in a statement that Duncan's liver function declined over the weekend. It said although it has since improved, "doctors caution that this could vary in coming days."
