"She is on BPAP therapy through endotracheal tube, while her heart rate and blood pressure remain stable. Her oxygen saturation and other ancillary blood reports are satisfactory," said the bulletin.

Sen's condition kept on fluctuating Saturday prompting Chief Minister Mamata Banerjee to rush to the nursing home for the third successive day. Doctors had to resort to emergency measures to stabilise her condition worsened.

During the day, state Congress president Pradip Bhattacharya also visited the nursing home and talked to the doctors monitoring her condition.

Following complications, Sen was put on the ventilator Jan 3.

Sen, dubbed as Greta Garbo of Bengali cinema, has remained an engima as she has avoided spotlights since her retirement.
