One thing I have learned as an RN is that a normal BP cuff on a person with bigger arms or just someone obese is that the BP reading is higher if you use a normal cuff.
Moral is, that if your arms are bigger than 15-16 inches you need a larger BP cuff for your reading to be accurate. A small cuff on someone with bigger arms will read a FALSE high reading. So, if your guns are big and they say you have hypertension ask "Did you use a larger cuff or the small one!"
Hope I didn't hurt any BP med sales!:smite::
