I bought a digital blood pressure device for my mother..previously she had a high blood attack luckily she survive but we still monitor more often,,,so i was decided to buy this digital thing...its makes me easy to operate too. rather than the other type the manual thing i dont know how to used to it...when i get her monitor blood pressure using the digital one I decide to make a comparison by using the other type and I asked my brother to used it also the other one... we were surprised and astonished that theres difference between the two by using it...so we dont know which of this two are accurate...
so maybe all digital devices such as digital thermometer, this blood pressure device . etc...has lead me to doubt...

Digital device especially healthcare devises are approximately 85% accurate, it may not be 100% relaible but when a continuos check is needed it is very imporatnt to ascertain health condition, glucometers are found more reliable than blood pressuure testing machines

Most devices are really sensitive and specific. But, most of them tend to need to be re-calibrated from time to time. As for all devices they do have times when they go crazy and provide inaccurate data. So, it is best to check calibration all the time.

If you took the blood pressure reading immediately after doing the first one, the reading was inaccurate. It takes awhile for the blood vessels to relax after being stressed with a monitor. Besides that, blood pressure naturally fluctuates throughout the day, so there's no good way to make a comparison unless there is a lot of difference.
The only digital monitors to stay away from are the wrist type. They do not measure accurately.

digital devices are quite dicey to believe.i feel it is always better to use the conventional instrument while taking your blood pressure. in fact even in the conventional method the mercury reading is suppose to be the most reliable one.When i was still doing my preclinical years , i remember my professor who told us never go short cut and he was deadly against all these digital instruments.So i would definitely say the manual one is the best. It is not tough to learn how to check the blood pressure. a couple of trial and error and you will know the way to do it.
