But threat perceptions to his life are very much there as he continued to be on ventilatory support, doctors attending on him said.

The medical bulletin issued on Sunday said Basu’s general condition was “marginally better compared to Saturday, but still critical” and he remained on partial ventilatory support.

The eight-member medical committee overseeing his treatment said Basu’s central nervous system was better than Saturday and he was “responding to calls.” According to one doctor in the board, Basu reportedly gestured with his hand feebly.

His cardiovascular function was “more or less stable,” with the blood pressure being maintained with stabilising medicines. Basu’s urine output has picked up under medication and there was no need for dialysis “at this moment,” the bulletin said.
