Outcomes

Primary Outcomes

Blood pressure mean deviation and standard deviation- evaluation criterion 1

The mean deviation and standard deviation between the blood pressure values measured by the investigational deviceand those obtained using the auscultatory method with the reference device. This calculation is performed on valid data pairsof subjects (n≥255). Evaluation criterion 1: The blood pressure mean deviation should not exceed ±5mmHg, and the standard deviation should not exceed 8mmHg.

Time frame: 30 minutes

Blood pressure mean deviation and standard deviation- evaluation criterion 2

The mean deviation and standard deviation between the blood pressure values measured by the investigational device and those obtained using the auscultatory method with the reference device. This calculation is performed on the valid data group of all subjects (m≥85). Evaluation criterion 2: The blood pressure standard deviation within the valid data group (m ≥ 85) should not exceedthe maximum allowable standard deviation corresponding to the mean deviation listed in Criterion 2 in section 5.2.4.1.2 b of ISO 81060-2:2018+AMD1:2020+AMD2:2024.

Time frame: 30 minutes

The mean deviation and standard deviation of blood pressure measurements under ambulatory blood pressure monitoring

The mean deviation and standard deviation of the blood pressure within the valid data group are calculated to evaluate whether the clinical accuracy of the investigational device meets the requirements outlined in ISO 81060-2:2018+AMD1:2020+AMD2:2024 , specifically in section 5.2.4.1.2a). The blood pressure mean deviation should not exceed ±5mmHg, and the standard deviation should not exceed 8mmHg.

Time frame: 30 minutes

The mean deviation and standard deviation of blood pressure measurements under exercise stress condition

The mean deviation and standard deviation of the blood pressure within the valid data group are calculated to evaluate whether the clinical accuracy of the investigational device meets the requirements outlined in ISO 81060-2:2018+AMD1:2020+AMD2:2024, specifically in section 5.2.4.1.2a). The blood pressure mean deviation should not exceed ±5mmHg, and the standard deviation should not exceed 8mmHg.
