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.

Treatment and study plan

Chest Worn Blood Pressure Monitor

Device

The Perin Health Patch (PHP) is an investigational, battery powered, wearable physiological monitoring device with an adhesive patch and sensor module, applied to the upper left chest. Cuffless noninvasive blood pressure measurements from the device were compared to a reference sphygmomanometer (dual observer auscultation, same arm simultaneous method).

Primary outcomes

Mean Error of Paired Blood Pressure Determinations (ISO 81060-2 Criterion 1)

Time frame: Day 1 through Day 7 (visit window up to Day 9 per participant)

Mean error (mmHg) of the individual paired determinations between the device under test and the reference sphygmomanometer (dual observer auscultation, same arm simultaneous method), calculated separately for systolic and diastolic blood pressure across all participants per ISO 81060-2:2018/AMD 1:2020. Acceptance criterion: mean error ≤ ±5.0 mmHg.
Standard Deviation of the Error of Paired Blood Pressure Determinations (ISO 81060-2 Criterion 1)

Time frame: Day 1 through Day 7 (visit window up to Day 9 per participant)

Standard deviation (mmHg) of the errors of the individual paired determinations between the device under test and the reference sphygmomanometer, calculated separately for systolic and diastolic blood pressure across all participants per ISO 81060-2:2018/AMD 1:2020. Acceptance criterion: standard deviation ≤ 8.0 mmHg.
Standard Deviation of Averaged Paired Determinations Per Participant (ISO 81060-2 Criterion 2)

Time frame: Day 1 through Day 7 (visit window up to Day 9 per participant)

Standard deviation (mmHg) of the averaged paired determinations per participant, calculated separately for systolic and diastolic blood pressure per ISO 81060-2:2018/AMD 1:2020. Acceptance criterion: the standard deviation must not exceed the maximum permissible standard deviation as a function of the observed mean error, per Table 1 (Averaged subject data acceptance) of the standard.
Device Accuracy During Induced Blood Pressure Change

Time frame: Day 7 (final study visit)

Mean error and standard deviation (mmHg) of paired determinations between the device under test and the reference sphygmomanometer during induced blood pressure increase (isometric resistance band exercise) and induced blood pressure decrease (relaxation) procedures, evaluated per IEEE 1708:2014 (including Amendment 1, 2019) and ISO 81060-2:2018/AMD 1:2020.
