Heart rate monitors need more interest, especially in children's wings. Below the green blip line, a jumping Super Mario punching coins out of bricks at the rate of your heart, accompanied by the classic Super Mario background music would add some horribly repetitive earworm noise to an otherwise dull
experience.
For comatose patients or those not yet awake from the anaestesia, the 'underground kingdom' music could play. And for patients whose hearts are racing or the nurses need called, the 'hurry up' music should kick on. Of course, for flatlines, the 'Mario loses a life' music should kick in.
