This attachment captures the time needed for participants to have the MEC physician obtain Blood Pressure (BP) values as usually done in NHANES using mercury and to have the health technicians obtain BP values using the Omron device. The second phase of the study will focus on comparing mean BP values assessed separately by mercury and Omron devices.

Suggested Script

For Phase Two: “As part of your examination today, you are having your blood pressure taken with two different devices. This is because we are doing a study to compare two different blood pressure measuring devices. Your participation to have a second blood pressure taken for the study is voluntary. The physician will (or may have already) given you information about your blood pressure.
