Suggest Treatment For Kidney Failure

My father had heart attack on 26th April.Angiography followed by angioplasty was done.Blockage was removed upto 50% .Was kept on medication to remove clots and then again the process was to be repeated.But his condition started detoriating and urine discharge was also less.Doctors told his Kidney is affected.We shifted him in critical condition to Delhi where treatment is going on.His Blood pressure fluctuates from 85/45 to 128/74.He has been on Dialysis and Ventilator since 30th.Doctors had removed the ventilator thrice during which he was breathing for one /two and four days without ventilator.Ventilator was initially connected through mouth,but on 22nd he was again put on ventilator which was connected through trachia.However Dialysis is stopped since yesterday morning.His urine output as of now is 50ml/Hr.
His present BP is 112/63.
Kindly advise.
