Oscillometric Arterial Pressure Measurements at Different Limb Sites
Germany84 participantsStarted 2025-07-29
Plain-language summary
This prospective, single-center observational study aims to evaluate the measurement performance of oscillometric arterial pressure measurements at different limb sites. Specifically, oscillometric arterial pressure measurements obtained at the upper arm, forearm, thigh, and lower leg with intraarterial arterial pressure measurements will be compared in non-cardiac surgery patients.
The results will provide insight into the reliability and accuracy of oscillometric blood pressure readings at alternative limb sites in clinical practice.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion criteria:
* Consenting patients ≥18 years scheduled for elective non-cardiac surgery with general anesthesia
* Patients in whom intraarterial arterial pressure monitoring with a radial artery catheter is planned
Exclusion criteria:
* Patients with systolic arterial pressure interarm differences \>20 mmHg
* Patients with severe peripheral arterial disease
* Patients with heart rhythms other than sinus rhythm
* Patients with contraindications for peripheral cuff placement (e.g., arteriovenous fistula, skin lesions)
* Pregnant women
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
