You or one of your family members may already be using a blood pressure monitor at home, but chances are that it may be giving highly inaccurate readings. This has been revealed in a new study published in the American Journal of Hypertension. The study has found that many blood pressure monitors used in homes are unacceptably inaccurate and they may create serious problems for people who rely on them to take blood pressure readings. The study found that these commonly available blood pressure monitors were giving wrong readings almost 70 percent of the times. When compared to the mercury reading of the sphygmomanometer, the household electronic BP monitors were found to be giving inaccurate readings of around 5 to 10 mmHG.
The study is being considered significant since millions of people use such household BP monitors and report the readings to their doctor, who then prescribes the medicine and decides further course of treatment. This could be very risky for the patient, the study said. The study was conducted by a group of researchers, one of whom is an Indian-origin individual named Raj Padwal. The study advises patients that they should not rely solely on these home BP monitors and should try to crosscheck with BP measurement devices available at hospitals and clinics. Further, patients should not change their drug dose based on just a few readings, the study says.
