Vibration Environment Criteria: Surgical (Operating Room, "OR) equipment instllation vibration environment criteria?
|
|
|
I am looking for the vibration environment criteria for surgical
equipment for a new hospital. The building will be deigned within a
year, and I need to know what maximum allowable floor vibrations from
other building mechanical equipment we should allow.
The closest previous criteria I can think of are those for MRI
installations. I have no idea what such OR equipment criteria limits
should be... are they tighter or are they more relaxed as compared to
those limits for MRI.
Comments welcome.

Perhaps I am missing something, but wouldn't that vibration level
criteria/requirement be specified by the manufacturer of the surgical
equipment? |

From personal experience, I found that a lot of manufacturers don't have
that info. They basically wait for one of their customers to have a
problem, measure the vibration level, then tell other customers "don't
exceed that level." |

Could you use VC curves as a guide? |

By simple logic you need to consider two cases: surgery and microsurgery
as well as the parameter staff distraction.
Generally my guess is that staff distraction will be a lower requirement
than what most machinery in the context needs and also that machinery
needs are easier to meet than staff needs. As an example it is quite
easy to put say a counting weight for small objects on a 1000 pound
insulating base and thereby obtain sufficient immunity from the
vibrations from nearby forklift work in a storehouse, but a lot less
simple to add similar vibration protection to staff members ....
Kind regards

Angelo,
I'm looking at pages 47.39 and 47.40 of the 2003 ASHRAE applications
handbook. It summarizes ANSI S3.29 and ISO 2631-2 (I don't have those
on hand to compare...)
They have a "human comfort" criteria curve for "Hospital Operating
Rooms and Critical Work Areas." That curve specifies a max allowable
RMS velocity of 0.004 in/s from 8 to 80 Hz. It looks like the curve
increases somewhat linearly from 8Hz to a max allowable level of
around 0.02 in/s at 1 Hz.
They have several other curves for microscopes of various
magnifications, different types of manufacturing equipment, and
surgical procedures of increasing delicacy. Also, less stringent
curves are shown for residences, offices, workshops, etc.
Regards,
Dave
