Lack of oxygen to the brain results in brain damage or death, depending on the period of time the brain is lacking oxygen. Depending on how long it took for rescue efforts to arrive she would have been starved of oxygen for that time. With the quick thinking and response of the young woman and gentleman they were able to keep oxygen to her brain.

Does that answer your question?
