Lower Body Negative Pressure to See if Noninvasive Monitors Are Accurate

Official title: Lower Body Negative Pressure to Validate Physiological Monitors

Run by Mayo Clinic · NCT07840144 · Data updated 2026-11-12

This study tests whether noninvasive physiological monitors accurately track body responses while the body experiences controlled lower body negative pressure.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are healthy, non-obese adults without systemic diseases, not on medications affecting autonomic responses, and not pregnant.

Probably not a fit

Patients with systemic diseases, on relevant medications, or pregnant individuals may not benefit from this validation.

What this trial studies

Researchers at Mayo Clinic will apply lower body negative pressure to healthy adults and measure how well noninvasive monitors reflect physiological changes. The study focuses on monitoring reliability during orthostatic stress without chronic diseases or obesity. Participants undergo specific exclusions to minimize confounding autonomic responses. The goal is to validate simple, noninvasive devices for safely tracking physiological status in stressful conditions.

Why it matters

Potential benefit: If successful, noninvasive monitors could reliably track vital signs during stress, aiding safer assessment in clinical or field settings.

How similar studies have gone: Previous work in orthostatic stress and monitor validation has shown promise, but this study adds a focused look at LBNP conditions.
