At Risk Patients

On a recent visit to hospital I noticed a sign on one of the bed matresses. OK I know you're not supposed to have phones on in there but I had to catch a snap of this - sorry for the focus, it reads "RECOMMENDED FOR USE BY "AT RISK" PATIENTS.

I just have vision of ill people surrounded by doctors in impending risky situations saying - "I'd recommend that matress there, yes the blue one.... aaaaarrrrrgggghhh!"
