Auscultatory and Oculometric BP Monitors

We used two different sphygmomanometers as reference monitors in this study. For auscultatory BP measurements, we utilized the Accoson Greenlight 300 (AC Cossor & Son [Surgical] Ltd., London, UK), an electronic and manual nonautomated mercury-free device; for oscillometric BP measurements, we utilized the Omron HEM-7121 (Omron Healthcare Co. Ltd., Tokyo, Japan), an automated device. Both devices utilize cuffs to measure BP; for this study, all patients wore the cuffs on the left upper arm at heart height while seated. As described above, BP was measured three times for each patient: before, during, and after exercise. The Greenlight 300 and the Omron HEM-7121 were used to measure BP before exercise. During exercise, the new monitor and the Omron HEM-7121 were used, and after exercise, the new device and the Greenlight 300 were used.
