Trial summary

In this study, the investigators are testing the accuracy of a wrist-worn measurement device by comparing its blood pressure measurement to arterial line (A-line) blood pressure monitors. The device is similar in style and fit to popular activity bands, but it is unique in that it measures blood pressure. Read more about this study

About this study

Official title: Accuracy of Non-Invasive Non-Oscillometric Blood Pressure Wrist Worn Measurement

In this study, the investigators are testing the accuracy of a wrist-worn measurement device by comparing its blood pressure measurement to arterial line (A-line) blood pressure monitors. The device is similar in style and fit to popular activity bands, but it is unique in that it measures blood pressure.

Read the detailed description

LiveMetric has developed a wrist-worn measurement device intended for use as a standalone device, designed for measurement of intermittent blood pressure for individuals suffering from hypertension or other conditions where monitoring of blood pressure is of importance.

The wrist-worn measurement device is intended to be worn on the wrist for intermittent measurements of Blood pressure.

The use does not require any special action from the user apart from wearing the band on either their left or right wrist. The device applies no inflatable mechanics or moving parts. The wristband is watertight and can be worn as any type of bracelet all the time or most of the time.

The study will include subjects that are hospitalized in the ICU and/or any of the cardiology departments or affiliating units such as Cath lab, heart transplant unit, etc..) and are continually monitored by an intra-arterial blood pressure line (A-line). A medical professional will measure simultaneous non-invasive auscultatory readings to determine the lateral difference for later adjustment of calculation. A medical professional or a company representative accompanied by a medical professional will place the device on the opposite limb than the one having the A-line, providing the location of the placement has intact skin. During the measurement stage, BP values are simultaneously recorded from the reference invasive A-line and the wrist worn device.

Questions about this trial

What is this clinical trial studying?

An observational study of Blood Pressure and Heart Failure, run by LiveMetric S.A. at 3 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 19 Apr 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Gabriel Sayer, MD (773-702-9396, gsayer@medicine.bsd.uchicago.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Non-Oscillometric Blood Pressure Wrist Worn Data Acquisition and Analysis (time frame: 2 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03919136, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Apr 2019.
