then change accordingly. For example,
the “patient” setting yields soft tones. The
“appendicitis” setting would change the
location of the red and green light, because
in endoscopic surgery, the computer screens
— typically suspended on gliders — shift up
and down the length of the patient’s body
depending on the location of the procedure.
Durup described a day in his ergonomic
lighting life: “We have a little control panel
in the room where you have the name of the 6
to 12 different procedures in each room, and
you have all the presets on this little control panel. So when we’re starting the operation, I can say to the staff, ‘Okay, now we
can change the lighting for this gall bladder
operation’ or whatever it is, then they press
gall bladder operation and the lighting in the
ceiling will change so that it’s fixed exactly
to this procedure.
“A standard preset could be ‘patient light,’
which is a more dimmed, nice yellow-red-dish light so that when the patient comes
into the room, when the patient is still
awake, you have a light setup that is actually
very calming and relaxing for the patient. So
that is the primary light setting. And then
when the patient is asleep and anesthetized,
then we can change to the procedure lighting. And that could, for instance, be a gall
bladder. And then we press the button called
‘gall bladder lighting,’ and then the presets
in the room will change for this operation.
“Then I can do the operation for the next
hour or so, and when I’m finished with the
operation, we can press the patient but-
ton again, and the patient will go out of
the room. And when the patient is out of
the room, we press another button, which
is called ‘cleaning light,’ and this is a very
white, very intense white lighting where you
can see everything in the room. You can see
blood and you can see dust and you can see
everything. So when the staff is coming to
clean the room for the next operation, they
have optimized lighting conditions for that
procedure (Fig. 6). And then for the next
operation, it could be something else. It
could be a liver or appendicitis or whatever
and you press a button for that procedure.
So that’s the way it works.”
It all comes at a price of around € 20,000
($21,400) to outfit a standard operating room
with a basic package. Extras can push it up to
around €40,000 or €50,000 and include things
like tie-ins to the building management sys-
tem, enhanced color mixes, additional zones,
and Wi-Fi that allows controls from a tablet.
The cost constraints of healthcare systems
can sometimes stymie uptake. Some users,
like Bispebjerg, have thus limited their deploy-
ment to 3 out of their 8 endoscopic units, and
to 2 out of 10 laparoscopic-specific rooms,
although they are planning to outfit many
more rooms with the technology with the
construction of their new hospital, planned
for completion in another 3 or 4 years.
Other hospitals have proceeded with more
extensive deployments. Aarhus University
Hospital, in Chromaviso’s home city, has the
largest installation, having outfitted about
100 rooms ( http://bit.ly/2cL4Fnn).
Odense uses it in about 35 rooms, and
is planning for many more installations
when it, like Bispebjerg, opens a new hospital, planned for 2022 in its case. Durup and
many of the users describe it as a technology
they cannot now live without.
Make no mistake about it: For them, the
ergonomic lighting elevates an ordinary
operating room to a cut above the norm.
