The Janesville Fire Department has upgraded its technology and equipment to better help overweight patients and reduce the risk of injury to emergency responders. The Janesville Gazette reports that Janesville ambulances are equipped with power-assisted stretchers that lower and lift. They can be attached to devices in ambulance beds that make helping patients into the vehicles less strenuous. Fire department employees say they're responding more often to calls involving obese patients, but that their new equipment isn't always enough.
