Child Rescued (?) from Under Rubble

Came across a clip entitled "Girl alive from the rubble in a neighborhood Almasranih 01/22/2014", but how the hell did a kid survive in the dust/rubble without air for so long ? The kid must have been starved of air for some time, considering she would have been buried under all that crap for a while before the rescuers arrived. But, how did they know this was the exact spot to dig ?
