A Novel Non-interfering Arterial Blood Pressure Monitoring Device

Not Applicable

Withdrawn

• Conditions: Hypotension; Hypertension; Healthy
• Interventions: Device: 3M; Device: ContiPressTM; Device: Mobil-O-Graph

• Registration Number: NCT01954446
• Lead Sponsor: Sense A/S

Brief Summary

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).

Detailed Description

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.

Primary Outcome Measures

Name	Time	Method
Accuracy of measurement	Up to 4 months	The reference measurements are compared with the measurements made by the investigational device

Secondary Outcome Measures
