Kolkata, Jan 4 (IANS): The condition of iconic Bengali actress Suchitra Sen, who was put on non-invasive ventilator support after her condition deteriorated Friday night, has stabilised since then, said a medical bulletin Saturday.

Sen's breathing problem had increased Friday leading to dipping of her oxygen saturation and thus necessitating the ventilator support.

"However, her oxygen saturation is still fluctuating continuously necessitating intermittent non-invasive ventilation," said the latest report.

She is receiving chest physiotherapy and her health condition has been reviewed by two chest specialists, said critical care specialist Subrata Maitra, part of the team of experts monitoring Sen at the Belle Vue Clinic here.

"Her oxygen saturation level which had dipped Thursday is now going up", said Abhirup Chakraborty, one of the doctors attending on her, adding, her vital parameters like heart rate and blood pressure are satisfactory.

Earlier in the day, her actress-granddaughter Raima Sen took to Twitter to relay the news.

"My grandma is better. Thank you for your prayers...Keep praying," Raima tweeted Saturday.

The veteran actress, 82, is undergoing treatment for a chest infection at the hospital since Dec 23. Suchitra was taken to the critical care unit (CCU) after her condition deteriorated Dec 28 night.

She is known for her performances in films like "Deep Jwele Jaai" and "Uttar Falguni" in Bengali as well as Hindi movies "Devdas", "Bambai Ka Babu" and "Mamta". She won the best actress award for "Saat Paake Bandha" at the Moscow Film Festival in 1963.

Suchitra, who is actress Moon Moon Sen's mother, quit acting in 1978. Since her retirement, she meets only a few people including her daughter as well as grand-daughters Raima and Riya Sen.
