Non-invasive blood pressure accuracy study for adults

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This interventional study collects paired non-invasive blood pressure (NIBP) and invasive aortic pressure data in a clinical setting to validate NIBP measurement algorithms. It follows IEC 80601-2-30 and ISO 81060-2 standards for accuracy of automated NIBP devices. Eligible participants are adults with a suitable cuff size and an arterial line as part of standard care, and who can consent and stay in the unit for the procedure. The study uses the NIBP Standard Parameter Module to assess algorithm accuracy across real-world conditions. Data from the study will inform device performance and potential improvements in NIBP measurement systems.

Why it matters

Who can join: the full rules

Inclusion Criteria:

1. Age requirement: 18 and over.
2. Have an upper limb (right OR left side) that fits the cuff size of the device (circumference ranging 17 cm to 40 cm) OR have a thigh (right OR left side) that fits a cuff size of the device (circumference ranging 38 to 50 cm).
3. Have an arterial line as a standard of care, which measures blood pressure at the aortic root.
4. Able to provide written informed consent.
5. Expected to remain in the unit for the duration of the study procedure.

Exclusion Criteria:

1. Have previously participated in this study (no subject may participate more than once).
2. Pregnant and lactating women per site standard of care.
3. Subjects with peripheral arterial diseases (causing left/right arm difference)
4. Hemodynamically unstable subjects at the discretion of the investigator.
5. Exhibited injuries, deformities, intravenous lines, or other abnormalities that, in the opinion of the Investigator, may prevent proper cuff application or functioning.
6. Are suffering from infection(s) or immunocompromised patients that require isolation.
7. PI or designee decision due to subject health conditions
