I still prefer the old mercury type blood pressure monitor. Most of the digital type has a great chance of interference from other electronic devices like cell phones.
IMO, the reality is that human BP measurement errors persist regardless of the device used to obtain the reading. I have not heard of the digital manometers being susceptible to interference of any electronic devices. However, Mercury is toxic, persistent and bioaccumulable. What do you do if there is a mercury spill?
