Noninvasive Blood Pressure Validation Study

The purpose of this study is to test how accurately the Perin Health Patch, a small wearable 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 pressure readings at the same time using a standard arm cuff and stethoscope. The patch readings were then compared to the standard readings to see how closely they match, following recognized international testing standards for blood pressure devices (ISO 81060-2 and IEEE 1708). Participants visited one of three study sites up to three times over about one week. At the final visit, participants also did light resistance band exercise to briefly raise their blood pressure and relaxation activities to lower it, so the patch could be tested while blood pressure was changing.

Inclusion Criteria: * Participant must have the ability to read and understand English and provide written informed consent. * Participant must be willing and able to comply with study procedures and duration. * Participant is an adult 22 - 90 years of age. * Participant must have an arm circumference in the range of the reference and calibration cuffs.
