I have worked with and without these though we refer to them as "pedestals". We will be gettting them in our new unit. The ones I have used are attached to the ceiling and take all the outlets - O2, suction,power etc as well as being docking stations for the monitor and underneath, the ventilator. The main advantage is that it stops the current problem of having to walk over power and other cords to get to the head of the bed. Because everything is one just one corner of the bed it becomes much safer and neater. Currently I always worry when I am washing hair because not only am I standing above power cords but just behind me is the bank of power outlets and although by law it has trip switches and safety mechanisms there is still 240 volts in all of that
