Hello docs... My doctor suggested me to keep monitoring ur bp... I am using digital omron bp machine at home...and check bp twice daily... Now I want to ask u is it reliable... I have heard that whatever reading comes on omron bp machine we should do minus( - ) 10 to that reading both systolic n diastolic... For eg if it comes 130/80 we should cut 10 degree...and actual reading is 120/70... Is it really so.. Someone told me no u should do +20 to both systolic n diastolic pressure... On omron machine... Plzzz help me docs...as u r all experienced... Which one is correct... ( -10 ) or (+ 20) to the reading ... Im really worried my bp comes 110/82 always on omron...
