We just got back from the hospital, where they got Dad stabilized again. They administered Tylenol, which lowered his temperature to 37.6 C (99.8 F). They also infused him with a drug to improve blood pressure and gave him a bolace (a quick way to inject fluid intravenously) of saline to increase his blood volume. They will also be infusing him with another unit of blood to improve his body's overall ability to oxygenate.

Please keep him in your prayers.
