Guernsey's Princess Elizabeth Hospital has been given a renal dialysis machine thanks to its League of Friends.
The league donated £13,000 for the equipment, which brings the number of such machines at the hospital to 10.
Ann Cullinan, Guernsey Renal Services matron, said it was needed as the number of people requiring dialysis on the island had doubled in five years.
She said: "It gives us flexibility in terms of the number of patients we can treat. It also gives a safety net."
Ms Cullinan said the sudden rise in kidney patients on the island was primarily due to an ageing population but also because people were being "picked up much earlier in primary care and referred through".
Barbara Minta, the League Of Friends chairwoman, presented the machine to the renal unit on Wednesday.
