Don't hold your breath for a quick rescue if you have to get a message relayed.

A woman in Oregon was on the phone with a friend in California when she tripped and fell backwards onto a glass coffee table. She dropped the phone as she fell. She was kind of embedded in the broken table, with the glass sticking into her. She screamed for her friend to call 911, hoping the phone hadn't disconnected when she fell. The friend called 911 in her locale, who seemed to have some difficulty in understanding the situation but finally called the authorities in Oregon, and they sent paramedics to the house. Forty-five very long minutes.
