Hi whats the difference between a wrist model and the pump model blood pressure units? Is there a difference between accuracy?
I curently have a omron blood pressure t5 intellisense but it shows a different pressure every time I test it? If I do one in one hand and do another one in other hand it would be different if I do a hand 2 times I will get different readings?

why is this
i also tested this on omron blood pressure auto m5 the same thing happened??
The reading were something like this:
( 119,68 ) ( 102,48 ) ( 112, 58 ) ( 115, 52 )
i wanted to know if this is the same with wrist ones do those have the same problem or do they have better accuracy?
Thanks alot
