Blanchard, Oklahoma (CNN) Jeff Litty is doing quick calculations in his head. The road between their house and the hospital in Norman, Oklahoma, is long. Some of it is gravel.
Should he call 911 and wait for an ambulance, or just put his wife in his pickup truck and drive her to the hospital?
He had awakened in the middle of the night to his wife, Tina Costello, moving erratically. She was complaining of tightness in her chest.
