The day after

It’s with isbi’s full consent that this shot goes onto Blipfoto - she’s looking pretty good, conducting video calls and getting herself out into the comfy chair (with some assistance), all within 24 hours of open heart surgery.
The extra shows all the colour coded tubes and wires hanging over the side of the bed. Now I know it’s an ICU where you expect all the fancy equipment but this looks a bit random - I hope somebody knows what all these colours mean and what they’re connected to.
