Bianchi, a 25-year-old Frenchman, underwent emergency brain surgery just hours after the incident occurred.
In the closing laps of the Japanese GP, a race affected by heavy rain associated with Typhoon Phanfone, Bianchi slid off course and collided with a recovery vehicle that was removing Adrian Sutil's car after the Sauber driver went off course and slammed hard into the barrier in turn 7. The safety car was immediately deployed following Bianchi's crash, and the race ended nine laps short of its 53-lap distance. Lewis Hamilton from Mercedes won the event.
The FIA said on Sunday that Bianchi was unconscious when he was transported by ambulance to nearby Mie General Medical Center. He could not be airlifted to the hospital due to poor weather conditions.
The Marussia F1 Team released a statement regarding Bianchi on Monday.
"Following the accident involving Jules Bianchi during yesterday's 2014 Formula One Japanese Grand Prix at Suzuka Circuit, the Marussia F1 Team would like to acknowledge the huge outpouring of support and affection for Jules and the team at this very difficult time," the statement read. "With regard to the communication of information concerning Jules' medical condition, we will respect, and be guided by, the wishes of the Bianchi family. Together with Jules' care, they will remain our highest priority.
"Therefore, we would ask for patience and understanding with regard to further medical updates, which will be communicated in conjunction with the Mie General Medical Center in Yokkaichi, where Jules is being treated, when they feel it is appropriate."
Representatives of the Marussia and Ferrari teams - Bianchi is a member of Ferrari's Driver Academy - will remain at the hospital to support him and his family."
