When father-of-two Bill McMartin began feeling unwell one morning in June, he didn’t think much of it. But by the time his wife Nia returned home from an appointment, it was clear something was seriously wrong.
Bill had collapsed. His speech was slurred. One side of his face had dropped. Nia recognised the signs of stroke immediately and called Triple Zero (000).
ͬɫ’s Mobile Stroke Unit (MSU) was dispatched and arrived within minutes. The team wasted no time. Using on-board hospital-grade technology, they conducted a CT scan, confirmed Bill was experiencing a stroke, and began taking life-saving action right there in his home.
Paramedic Robert Greenwood, who treated Bill during emergency transport to Monash Medical Centre, said the MSU’s ability to diagnose and treat stroke on scene is a game-changer.
“Every minute matters when it comes to stroke,” Robert said. “The Mobile Stroke Unit allows us to start treatment before we’ve even left the patient’s home and that can mean the difference between recovery and lifelong disability.”
Bill was rushed under lights and sirens to hospital, where the hospital stroke team was prepared to continue his care thanks to the MSU’s early diagnosis and live coordination with clinicians.
For Nia, the experience was overwhelming, but the speed and professionalism of the paramedics gave her confidence in a terrifying moment.
“Our world was turned upside down when Bill had the stroke,” she said.
“The Mobile Stroke Unit played a vital role in making sure he got the help he needed as quickly as possible. We’re so thankful to ͬɫ and to the paramedics who cared for him, they were just amazing.”
Victoria became home to the first Mobile Stroke Unit in the Southern Hemisphere in 2017, the second hit the road in 2024.
They are purpose-built ambulances equipped with CT scanners, telemedicine link to neurologists and mobile pathology labs. Each crew includes a neurologist, stroke nurse, radiographer, and two paramedics including a Mobile Intensive Care ͬɫ (MICA) paramedic.
ͬɫ encourages Victorians to familiarise themselves with the signs of stroke.
Learn the signs of stroke using the F.A.S.T. test:
- F is for Face – Has their mouth drooped?
- A is for Arms – Can they lift both arms?
- S is for Speech – Is their speech slurred?
- T is for Time – Time is critical. Call Triple Zero (000) immediately.
The MSU initiative is a collaboration between ͬɫ, The Royal Melbourne Hospital, Monash Health, the Florey Institute of Neuroscience and Mental Health, the Stroke Foundation, the RMH Neuroscience Foundation, the Victorian Government, and the NHMRC and is made possible through generous community donations and funding support. Community contributions help ͬɫ deliver specialised care and improve patient outcomes across Victoria.
