Her body limp and her skin blue, a 12-year-old girl was pulled from a pool Sunday and revived by relatives -- who learned CPR from television shows -- and three rescuers who raced to a Bogota back yard.

Heather Hernandez, visiting from California, was in good condition at Hackensack University Medical Center. She apparently had suffered a seizure, her family said, and slipped under water.

"The weird thing is, we were standing right there," said Willie Ortiz, the girl's uncle. "We have a fence. We have a lock to make sure nothing happens. We were supervising them."

The incident occurred about 3 p.m. when Ortiz's 4-year-old son, Willie Jr., called to the adults in the Fairview Avenue back yard.

"Look! She doesn't want to come out," said the boy, who had been swimming with Heather.

Ortiz saw his niece floating facedown. Fully clothed, he jumped into the 4-foot, above-ground pool and pulled Heather out.

"She was blue," Ortiz said.

With his wife, Sandra, Ortiz started cardiopulmonary resuscitation. "I just learned it from the TV," Willie Ortiz said.

A visitor called 911, drawing Bogota Patrolman Robert Piterski and Lt. Bill Graf as well as Tito Jackson, an emergency medical technician who heard the call en route to his job at Hackensack University Medical Center.

The three arrived to find CPR in progress but Heather getting no oxygen.

"She did have a pulse, but she wasn't breathing," Jackson said. "She was pure blue. We put an airway in and just started giving her oxygen, pushing air into her lungs."

Moments later, Heather was coughing and crying and on her way to the hospital.

Piterski and Graf, whose shifts ended shortly after the rescue, were not available for comment.

"If they hadn't been on, the outcome may have been different," police Detective James Sapp said.

By 8 p.m., Heather was alert and talking, Ortiz said, and scans showed no sign of injury.

"They think it may have been a seizure," Ortiz said. "She's staying with us for two weeks on vacation. She came on the plane [Sunday] morning. Maybe she was just tired and fainted."

Despite his detour on the way to work, Jackson was on time for his shift, minus his customary cup of takeout coffee.

But Jackson -- who in addition to working at the hospital is a 17-year veteran of the Bogota rescue squad and supervisor of the Fort Lee ambulance squad -- had no complaints.

"I'm usually around when something happens," Jackson said. "I kind of have a black cloud over my head. But I'll go home and say, 'You know what? Today was a good day.' "
