Comparison of Non-Invasive Blood Pressure Methods

Not Applicable

Completed

Brief Summary: The primary objective of the study is to demonstrate the accuracy in healthy adults with Vital USA Device by comparison to a non-invasive (auscultatory) reference sphygmomanometer.

The procedure, data collection methods and data analysis that are outlined in the protocol follow the standard: International Standards Organization (ISO) 81060-2:2018 Non-invasive Sphygmomanometers - Part 2: Clinical validation of automated measurement type.

Detailed Description: This study will include up to 100 adults ≥ 18 years of age. The final subject database will contain no fewer than 85 subjects with a minimum of 255 paired observations. At least 90% of the subjects will contribute 3 paired observations, if necessary the balance of the data will be added from additional subjects.

An interim analysis will be conducted at the end of Part 1 data collection and will consist of simple statistics that will compare the test device tot he reference cuff non-invasive (auscultatory) reference sphygmomanometer.

Part 2 data collection will be conducted after Part 1 data collection interim report is reviewed and additional data collection is approved by the client. It will test an additional 55 subjects (plus extra subjects as replacements if necessary).

Group	Intervention	Description
ISO 81060-2:2018.	The Vital Detect blood pressure monitor	The intended purpose of the test is to evaluate the Vital Detect blood pressure monitor to ISO 81060-2:2018. The intended use for these products are manual and automatic Non-Invasive Blood Pressure monitoring on adults age 18 and older.

Primary Outcome Measures

Name	Time	Method
Validate Non-invasive Blood Pressure Measurement Accuracy for the Vital Detect Blood Pressure Monitor.	1 Hour	The primary objective of this study is to provide a validation for non-invasive blood pressure measurement accuracy for the Vital Detect blood pressure monitor when compared to the Reference Sphygmomanometer. Data taken was based on dual observers (Criterion 1(C1), Criterion 2 (C2) for both Systolic and Diastolic determinations. Since the same arm sequential method was used, data for a given subject were averaged to create the reference blood pressure determination against the acceptance criteria. The device under test (DUT) passed or failed the determination based on the mean error and standard deviation of the determination. The acceptance criteria: Criterion 1: Mean Error Standard Deviation (Systolic / Diastolic) (Systolic / Diastolic) \</= 5.0 mmHg \</= 8.0 mmHg Criterion 2: Standard Deviation (Systolic) (Diastolic) \</= 5.33 mmHg \</= 6.09 mmHg
