Heche’s condition has not improved in the days following her fiery Los Angeles car crash, reports people.

A rep for the Emmy winner, 53, said in a statement to PEOPLE that Heche is now in “critical condition” at the hospital.

“She has a significant pulmonary injury requiring mechanical ventilation and burns that require surgical intervention,” the rep says. “She is in a coma and has not regained consciousness since shortly after the accident.”

Heche was in a blue Mini Cooper on Friday that crashed into a Mar Vista home rented by Lynne Mishele. The residence caught fire, resulting in the Emmy-winning actress suffering burns from the incident. She was then intubated while hospitalized.

At this time, Los Angeles authorities are still investigating the incident.
