Intensive care units are on the frontline of the coronavirus pandemic, working to keep the most seriously ill patients alive.

Access into these units is extremely restricted, but I was allowed to spend a 12-hour shift with the overnight ICU team at Hairmyres Hospital in East Kilbride.

Hairmyres Hospital normally has one intensive care unit, but now there are two Covid wards and two ICU areas for Covid patients.

The primary ICU has been running at 240% capacity for most of the Covid crisis, and its equipped to flex up to 400%.
