FROM personal experience, Sam Cavallaro knows how important dialysis is.
The former president of Liverpool/Greenway Rotary Club helped raised close to $20,000 for an ultrasound machine for Liverpool Hospital's renal unit.
Patients can take the portable machine home.
It is used to provide images for cannulation, which can be tricky for patients receiving home treatment.
Cannulation requires a cannula (tube) to be inserted into the body.
Mr Cavallaro has a great understanding of how such procedures work, having watched his younger sister go through dialysis after she was diagnosed with failed kidneys.
"I was 18 when my sister was on dialysis," he said. "It was quite a traumatic experience for the whole family."
The Liverpool/Greenway Rotary club raised money for the new machine through their annual charity ball.
Liverpool Hospital renal home therapies clinical nurse consultant, Susana San Miguel, said the machine was making a difference to the lives of patients.
"It's helping patients do the treatment by themselves by building their confidence," she said.
"If patients have problems with inserting the cannula at home they can use the ultrasound machine to see the veins in their arms.
"For nurses, it prevents complications of cannulation because they can see the veins instead of feeling for them."
