I have maintenance medication for high blood pressure so I am prescribed to have a reading of my blood pressure once in a while. A trip to the clinic requires effort and the nurse or the physician is not free of charge so we decided to buy a digital monitor which is an equivalent of the spygmomanometer. Cheap at $40, we didn't hesitate with the purchase. However, when we tested it at home, I was disappointed because the reading I got was 190/110. That blood pressure would have killed me on the spot. My husband tried it and he got 160/90 which is impossible because he is always normal with his blood pressure reading of 120/80. That digital monitor just confused us and we are thinking of how to make good use of it.
