The hospital at night

For a place that never sleeps, the hospital was a very eerily quiet place at 2am this morning.
Didn't mind being in there at that time- when I took this pic I was on my way out after being called to see a very unwell, elderly gentleman.
Oxygen saturations of 76% on arrival (extremely poor), 99% (a while lot better) by the time I left.
A broken nights sleep well spent.
