When a cellular phone receives an SMS packet or is receiving an incoming call, it will frequently cause VERY loud "beep bu-deep beep beep" sounds in almost all types of speakers. This interference is usually not visible in waveforms, in my experience, but I wouldn't even allow a cell phone in an exam room. At all! Period!

I bet most of us have experienced this at least a few times.

At the very least, make sure the patient puts it in airline mode.

I am soliciting opinions here.

My 2nd patient this morning asked if it was OK to take a phone call
during her carotid exam.  I asked if the call she was expecting was a
matter of life or death. She stated that it was not, but an important
call about a business venture.  I told her I understood the significance
of her call, but that my answer was no, then told her why.

But it got me to thinking; how are the rest of you in the vascular
community dealing with issues like this?  The woman asked pleasantly and
was told pleasantly that no, it was not possible to talk on the phone
and get an accurate carotid exam simultaneously.  Doesn't common
etiquette dictate that since she was there for an exam that, by
definition, she gives up a little of her time for me to do my job?
Would you ask a CT or MRI tech the same question?  How about the dental
hygienist or even the dentist, the surgeon, the PA or the nurse?  My
biggest problem with her asking the question is that the incessant use
of cell phones has become so pervasive that people now ask you if it is
OK to be rude, right to your face.

You can now buy large, colorful posters to place in waiting rooms with
long and boring explanations, with cell phones in red circles with lines
drawn through, with pictograms showing electrical shocks and even in
different various  languages...VERBOTTEN, PROHIBE, INTERDIT,

It is an interesting issue with many facets.  I'm sure opinions on the
matter range from the sublime to the militant.  Fire away!
