A woman in her 70s has sustained a serious head injury following a collision between her bike and a vehicle in Mosman this morning.

An off-duty emergency doctor was the first responder on scene and provided assistance until medical crew arrived.

CareFlight’s Rapid Response Helicopter was tasked by NSW Ambulance after 9am and landed 20 minutes later at Sirius Cove Park, Mosman.   NSW Police escorted the clinical team to the scene of the incident where NSW Ambulance paramedics were providing initial treatment.

CareFlight’s specialist doctor and NSW Ambulance critical care paramedic performed a clinical assessment on the woman, intubated and placed her in an induced coma to stabilise her.

The woman was taken by road in a critical condition with NSW Ambulance to Royal North Shore Hospital under ongoing observation from CareFlight’s clinical team.
