Arrowhead Regional Medical Center in Colton’s Trauma Coordinator and Registered Nurse Jan Serrano describes the dangers of leaving a child in a parked vehicle in warm weather and explained that a child could die from hyperthermia in as little as five minutes. She also described the medical center’s month-long campaign to remind staff, patients and hospital visitors about the danger during August, which is “Purple Ribbon Month” and that it is illegal to leave a child in an unattended vehicle under “Kaitlyn’s Law.” She also said that at least 22 children have died in the U.S. from hyperthermia so far in 2011. Last year, there were at least 49 fatalities in the U.S. Since 1998, there have been at least 516 such fatalities, according to San Francisco State University.
