Study of CART BP Wearable Ring Device for Cuffless Blood Pressure Monitoring Compared to Traditional Method Evaluating Accuracy by Arm Position and Exercise Effects in Adults 18 to 79 Years

What this Trial Is About

Researchers are evaluating the accuracy of the CART BP, a wearable cuffless blood pressure monitor, compared to the traditional auscultatory method using a dual-head stethoscope. This study follows the 2023 European Society of Hypertension recommendations and focuses on patients with suspected high or low blood pressure. The evaluation looks at measurements taken in different body positions and during various exercise activities. Participants prescribed a 24-hour ambulatory blood pressure monitor will use both the CART BP ring device and a standard sphygmomanometer simultaneously to measure blood pressure and pulse rate. The study includes measurements with the arm positioned significantly lower than usual and after repeated handgrip exercises to assess changes in blood pressure accuracy under different conditions. During the study, participants will have their blood pressure monitored continuously over a one-hour period, and researchers will measure the mean error and variability between the CART BP and the traditional method. Participants must comply with the study protocol and provide consent, with monitoring including exercise tests and posture changes. The total participation duration and follow-up details are consistent with the 24-hour blood pressure monitoring period.
