A 19-year-old man has sustained serious head injuries, and another four people have been injured and taken to hospital when two cars crashed in Mulgoa, Penrith earlier today.

CareFlight’s Rapid Response Helicopter was tasked by NSW Ambulance to the scene of the motor vehicle crash at 4.47pm today, landing just 30 minutes later in a yard metres from the scene.

NSW Ambulance paramedics provided initial treatment to the five occupants of the two vehicles involved in the crash.

Once on the scene, CareFlight’s specialist doctors and NSW Ambulance critical care paramedic assessed and treated the most seriously injured, the male driver and only occupant of one of the vehicles. The team intubated the man to stabilise him and transferred him into the helicopter.

He was flown, under the clinical supervision of CareFlight’s doctor to Westmead Hospital in a serious but stable condition.

The female driver of the second vehicle and her three passengers were also injured. The woman, believed to be in her 30s and her two daughters aged six and nine, and another female aged 64, were all treated for injuries sustained in the crash at the scene and taken by road ambulance to The Children’s Hospital at Westmead and Westmead Hospital for further treatment
