One ambulance wasn't enough to get Patricia Green, 25, suffering from internal bleeding, and her boyfriend to the hospital yesterday. It took four in all.

Green and her rescuers needed to be rescued when the D.C. ambulance speeding Green and her boyfriend, Christopher Denny, from Denny's home on 30th Street NE to Providence Hospital was broadsided by a car, police said. Green, Denny, the two ambulance attendants and the car's driver were all slightly injured, and three more ambulances had to be called to take them all to various hospitals.

The accident occurred as the ambulance from Engine Company 12 was traveling north on South Dakota Avenue with its emergency lights flashing, police said. It stopped briefly for a red light at Michigan Avenue, then started to cross the intersection about 7:15 a.m.

University of Maryland student Robert Caffrey, 21, driving through the intersection east on Michigan Avenue, apparently didn't see the ambulance and slammed into it, police said.

Caffrey, of College Park, was treated and released from Providence Hospital, as was the ambulance driver, Charles Forrester Jr., 21, of Boulevard Heights, Md. Green, of 1210 Michigan Ave. NE, also taken to Providence Hospital, was reported in satisfactory condition from her combined infirmities.

Lanae Kelley, 32, of Columbia Road NW, an ambulance attendant, was treated at George Washington Hospital for minor smoke inhalation from a small fire in the accident, and was released. Denny was taken to the Washington Hospital Center, where he was reported in serious condition.

Caffrey was charged with failure to yield the right of way to an emergency vehicle.
