What we do
We care for patients requiring surgery for heart and lung conditions.
The adult surgical unit (ASU) has 40 beds and is divided into two wards - Cedar and Maple. Cedar Ward, on the second floor, has 25 beds, and Maple Ward, on the ground floor, as 15 beds.
Life on the ward
All patient areas are located in the main hospital buildings and are easily accessible from the main reception and a lift is available if needed.
Wards offer separate male and female accommodation and bathing areas are segregated. A few single rooms are available and are allocated on clinical need.
