A Novel Non-interfering Arterial Blood Pressure Monitoring Device

A Novel Non-interfering Arterial Blood Pressure Monitoring Device

The primary purpose of this investigation is to validate the performance and safety of the Investigational Device (ID) against a validated and legally cleared device for measuring Blood Pressure (BP). The secondary purpose is to validate the performance of the ID over a period of 24 hours against a validated and legally cleared device for Ambulatory Blood Pressure Monitoring (ABPM).

The clinical investigation is conducted as a controlled (subject as own control), prospective, randomised, comparative investigation in a population with a representative spread of BPs to ensure that the ID performs as good as current marketed and approved devices. The study will be conducted in compliance with the International Standard ANSI/AAMI/ISO 81060-2 - Non-invasive sphygmomanometers - Clinical validation of automated measurement type.

This clinical investigation will enrol up to 96 male and female subjects to ensure the recording of 85/35 evaluable datasets in accordance with the ANSI/AAMI/ISO standard [11]. All measurements will be paired and falls into 2 categories: Auscultatory measurements as gold standard reference, oscillometric measurements for clinical practise reference and further validation of ambulatory monitoring and pulse shape measurements.

Inclusion Criteria:

• At least 30% of the subjects must be males (n=29)

• Blood pressure distribution:
• At least 25 % of the subjects should be hypertensive
• At least 5 % of the subjects should be hypotensive
