Thanks for your question on Chat Doctor. The gap of 7 minutes to achieve heart function is too crucial.  And brain damage is definitely there as time is 7 minutes. In body, brain regulates everything. Blood pressure, heart rate, breathing etc. So I think your sister is having hypoxic brain damage as in that 7 minutes, blood supply of brain might be zero and so there may be brain damage. Other evidences which favors brain damage are1. Seizure episodes if we decrease propofol2. Fall in BP awe decrease dopamine. So better to get done EEG (Electron Enceohalo Gram) and CNC examination. If EEG is not showing any brain activity then chances of survival are very, very low.
