B40 Non-Invasive Blood Pressure Equivalency Study

This study has been completed.
Information provided by (Responsible Party):
GE Healthcare Identifier:
First received: February 28, 2012
Last updated: May 2, 2013
Last verified: May 2013
The purpose of this study is to demonstrate equivalency of the GE Healthcare B40 Patient Monitor noninvasive blood pressure (NIBP) parameter compared to the reference device.

Condition Intervention
Blood Pressure
Device: Blood Pressure Readings on B40 Patient Monitor

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Diagnostic
Official Title: B40 Non-Invasive Blood Pressure Equivalency Study

Further study details as provided by GE Healthcare:

Primary Outcome Measures:
  • Difference Between the B40 Monitor and Reference Device DINAMAP PRO1000 on NIBP Measurements [ Time Frame: End of each blood pressure reading ]
    The primary endpoints are the difference in systolic, diastolic and mean blood pressure values between the B40 Monitor and PRO1000. The mean of the difference should be no more than 5mmHg and the standard deviation of the difference should be no more than 8mmHg per the AAMI SP-10 standard.

Enrollment: 66
Study Start Date: March 2012
Study Completion Date: March 2012
Primary Completion Date: March 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Blood Pressure Reading
Simultaneous blood pressure readings with DINAMAP PRO1000 and B40 monitor; total of 6 successful readings
Device: Blood Pressure Readings on B40 Patient Monitor
Simultaneous blood pressure reading on the Investigational B40 patient monitor and DINAMAP PRO1000 patient monitor

Detailed Description:

Automated non-invasive blood pressure devices have a long history. These devices first made their appearance in the mid-1970's. Since that time, there have been many improvements in the performance of these devices. Specifically, when making changes to the algorithms that control these devices, the goals are: to improve accuracy and precision in the blood pressure (BP) estimates, to reduce the time needed to determine the BP estimates, to increase comfort for the patient, and to work through artifacts and arrhythmias that are often present in the clinical environment.

The purpose of this study is to demonstrate equivalency of the GE Healthcare B40 Patient Monitor noninvasive blood pressure (NIBP) parameter compared to the reference device.
