The 64-year-old actor, who has starred in films like 'Ardhasatya' and 'Sadak', was admitted to Kokilaben Dhirubhai Ambani Hospital here two weeks ago after being diagnosed with a lung infection.
Sadashiv's daughter Reema, who is a Marathi filmmaker, said that her father is responding well to treatments at the hospital.
"Sadashiv ji is on ventilator and stable. He is also showing signs of improvement. Please don't believe any rumours. I will update you if there is any change," Reema said.
Sadashiv was last seen on the big screen in 2012 film 'Bombay Talkies'.
