A 12-year-old boy performing jumps on his bike at a property in Mona Vale has knocked himself unconscious while riding at a high speed on a ramp.

The boy sustained facial injuries from the impact and bystanders administered first aid.

CareFlight’s Rapid Response Helicopter was tasked by NSW Ambulance shortly before 4.00pm and landed less than 15 minutes later in the grounds of the property where NSWA Ambulance paramedics had also just arrived.

Working with bystanders, CareFlight’s clinical team worked to extricate the boy from the ramp. CareFlight’s specialist doctor and NSW Ambulance critical care paramedic performed a clinical assessment on the patient and conducted an ultrasound at the scene of the incident.

CareFlight’s clinical team continued providing care as the boy was airlifted in a stable condition to The Children’s Hospital at Westmead.
