I am really upset by the experience I had this week end.
I am now 38 years old and thought it would be a good idea to start watching my blood pressure since both my mother and father have slightly high blood pressure.
So I head to Wal-Mart and bought a blood pressure monitor. I get it home unpack it, read all the directions, and then take a reading.
155 over 111. WHOLLY $HIT. I panic and go to see my doctor the very next day. She takes my blood pressure 130 over 80. I ask her to take it again in five minutes 135 over 74. She tells me maybe the machine I bought is miss-calibrated.
I go back to Wal-Mart and use their sit down machine and measure my blood pressure. 130 over 79. Then I use the machine I bought which I brought back to the store with me. 151 over 108. I then continued to test five other machines from the shelve against the sit down machine Wal-mart owns. Would you believe four of those machines had a 10% to 25% error margin against the sit down machine. BTW the machine Wal-Mart owns gave me almost the exact same reading every time.
My question is, How can a company manufacture and sell an important piece of health equipment which does not give an accurate reading? What if someone did in fact have high blood pressure and the machine they bought gives them a low reading? Is there an agency that regulates this type of equipment?
