Apologies: GRAPHIC
When I looked at the floor tiles that had the most amount of blood, it appeared to have cerebral spinal fluid (CSF) intermingled causing the bubble look.
I have treated patients with severe head trauma such as Teresa sustained. Needless to say, it is horrific to see. Those times were the only times the room has ever tilted for me.
More than likely she was unconscious very quickly from the blunt force trauma. It appeared to me that most of the blows she sustained were while she was motionless on the floor. Total supposition on my part from looking at the floor. ER floors have looked like that too in the aftermath of a Trauma Code involving severe head injuries.
Those



showed no mercy.
