Noninvasive Blood Pressure Validation Study

The purpose of this study is to test how accurately the Perin Health Patch, a smallwearable sensor worn on the chest, measures blood pressure without using an arm cuff.Adults 22 to 90 years of age wore the patch while trained observers took blood pressurereadings at the same time using a standard arm cuff and stethoscope. The patch readingswere then compared to the standard readings to see how closely they match, followingrecognized international testing standards for blood pressure devices (ISO 81060‐2 andIEEE 1708). Participants visited one of three study sites up to three times over aboutone week. At the final visit, participants also did light resistance band exercise tobriefly raise their blood pressure and relaxation activities to lower it, so the patchcould be tested while blood pressure was changing.
