A 78-year-old man has fallen from his ride-on lawn mower on the property of his Galston residence and sustained injuries to his head when he hit a guard rail.

He lost consciousness from the impact and bystanders provided first aid for the man.

CareFlight’s Rapid Response Helicopter was tasked by NSW Ambulance at 11:15am and landed 15 minutes later in an adjacent property where NSW Ambulance paramedics were providing initial treatment.

CareFlight’s specialist doctor and NSW Ambulance critical care paramedic performed a clinical assessment on the man and conducted an ultrasound to assess his injuries.

The man was taken by road in a stable condition with NSW Ambulance to Westmead Hospital under ongoing observation from CareFlight’s clinical team.
