The condition of legendary Bengali actress Suchitra Sen, who was put on non-invasive ventilator support after her condition deteriorated, is stable in comparison to previous days, but she is not out of danger yet, a doctor said Tuesday.

She was put on the ventilator Jan 3.

Ruling out any plans to discharge her from the hospital, Subir Mondal, member of the team of seven experts monitoring Sen at the Belle Vue Clinic here, said her oxygen saturation level has gone up in the last few days.

"She is not out of danger yet...her oxygen saturation is not fluctuating much at the moment. We have no plans of discharging her as she is not that stable," Mondal told IANS.

On Monday, the doctors said her respiratory tract infection is under control though it still remains detrimental to her health.

The 82-year-old actress was undergoing treatment for a chest infection at a nursing home since Dec 23 and was taken to the CCU after her condition worsened Dec 28 night.

One of the finest actresses of her time, she is known for her performances in films "Deep Jwele Jaai" and "Uttar Falguni" in Bengali as well as Hindi movies "Devdas", "Bombai Ka Babu" and "Mamta".

Her work was appreciated offshore too - she won the best actress award for "Saat Paake Bandha" at the Moscow Film Festival in 1963.

The mother of actress Moon Moon Sen, Suchitra quit acting in 1978. Since her retirement, she has been meeting only a few people, including her daughter as well as grand-daughters Raima and Riya Sen.

However, in a rare exception, Sen Sunday allowed West Bengal Chief Minister Mamata Banerjee to meet her at the nursing home.
