Lola Cavalli — whom Entertainment Tonight identified as one of the first people on the scene to call 911 and gave medical aid to Pax, 20 — told the outlet she called emergency services immediately after the crash and tried to apply pressure to his head to stop any bleeding.

“I didn’t see any broken bones. I did not see, like, profound bleeding, so to speak,” Cavalli said. “And since I was directed to apply pressure at the site where it was bleeding, I did not see where I could apply the pressure, because it was on the head. He was hit on the head — I had no idea where you would put the pressure to stop the bleeding on the head.”

“It was not a lot of blood. You didn’t see, like, a fountain of blood rushing out,” she added. “His mouth was filled with blood. When [he] was trying to speak, I saw a little tiny stream of blood coming out of the mouth.”

Pax, one of Angelina Jolie and Brad PItt’s six children, was hospitalized after the incident on Los Feliz Boulevard on July 29.

While speaking with ET, Cavalli added that she grew concerned with oncoming traffic still moving throughout the street even as she helped Pax and waited for first responders to arrive.

“We did everything we thought would be necessary to make sure that the ambulance arrived, and [to make sure] oncoming traffic from both directions keeps on moving, instead of piling up, which would make our ambulance’s approach impossible completely,” she told the outlet.

A source told PEOPLE on Aug. 5 that Pax had been released from an ICU ward following the incident and that he “suffered complex trauma, and now begins the long road of recovery and physical therapy.”
