Floor-Mounted Cath Labs vs Ceiling-Mounted Cath Labs

Floor-mounted cath lab vs ceiling-mounted cath lab.jpgWhen people begin searching for a cath lab system, one of the first things they tend to notice is that there are TONS of options! Single plane or bi-plane? Which detector size? Want to add a hemodynamic monitoring system to that? How about an injector? The list of possible configurations goes on and on.

Most folks are able to arrive at relatively quick decisions on many cath lab options, but we often see some confusion when it comes to choosing floor mounting or ceiling mounting. Both types require a facility to install a ceiling structure, so does it really matter how the lab is mounted? Absolutely! And in more ways than one. To show you what we mean, we'll break down the differences that might inform your choice of either a floor-mounted or ceiling-mounted cath lab system. For comparison's sake, we'll use the GE Innova 3100 IQ (floor-mounted) and Philips Allura XPER FD20 (ceiling-mounted) as examples.

Cath Lab Ceiling Structure Loads

As we mentioned earlier, whether your cath lab's gantry will be mounted on the floor or the ceiling, you will need to install some kind of support structure in the ceiling of your future cath suite. The difference is the amount of weight that structure will need to bear. In the case of most floor-mounted systems, including our example, the Innova 3100, the only equipment that will need to hang from the ceiling is the monitor boom, with surgical lights and a lead shield as options. All of these items combined weigh about 700 pounds.

Our ceiling-mounted example, the FD20, has a similar monitor/light/shield weight of around 764 pounds (give or take, depending on the options you choose for your specific system). Unlike the Innova, however, the ceiling structure also needs to be able to support the FD20's 2,557-pound gantry, for a total of 3,321 pounds. Installing a structure that can bear this load will involve far more labor and heavier-duty materials than a structure for a 700-pound load. For ceiling-mounted labs, installing heavy-duty ceiling structure will account for several thousand dollars of your installation quote.

Cath Suite Ceiling Height/ Floor Level

With a least a portion of the equipment hanging from the ceiling in either case, there are some recommendations about minumum ceiling heights. Since the GE system is just the monitors and light/shield hanging, there is some flexibility. GE recommends 9’6” from finished floor to finished ceiling for the Innova's hanging components, but gives some leeway in offering a minimum height of 9’, and a maximum deflection of 1/16” when the rails of the structure are under load.

The FD 20 is a very different story. Because the gantry interacts with the table, there are very specific requirements that must be adhered to in the site planning process. Philips requires a ceiling height of 9’6 3/16” with an allowance to be up to 3/8” higher, but not any lower. The ceiling must also be square and level to within +/- 1/16” per 39”.

When working with the FD20, you also have to take into account the full movement of the gantry, and ensure the floor is level within the same tolerances as the ceiling – 1/16” for every 39”. In contrast, the floor for the GE unit must be level 1/8” over 10’.

If you're installing a cath lab into an existing building, the choice of which mounting style to use may be influenced by your current ceilings and floors as well as your appetite for taking on possible remodeling costs.

The Takeaway

So, when people ask us if they should get a floor-mounted or a ceiling mounted system we tell them this: If your ceilings are already 9'6" and change, you can't really go wrong with either. Systems in both categories will serve your patients and your physicians well. If your ceilings are lower, you can save yourself some remodeling costs by choosing a floor-mounted system.
