The non-invasive central venous pressure estimation in adult cardiac intensive care units (CICU) patients study is a single-center, single-arm, investigator-blinded, interventional, intra-participant comparative, feasibility study. This study aims to assess the safety and preliminary accuracy of external jugular venous occlusion pressure measured non-invasively with the venous occlusion pressure monitoring device (CPMX2) in adult CICU patients. As a feasibility study, the primary goal is to gather preliminary data on the feasibility, safety, and effectiveness of the non-invasive CVP estimation method. Although single arm, the study will compare non-invasive CVP measurements with standard invasive CVP measurements taken concurrently. This intra-participant comparative approach is essential to validate the correlation and reliability of the non-invasive method.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Provision of signed and dated informed consent
* Admitted to the CICU with invasive CVP/RA pressure monitoring placed by standard of care as determined by the treating team before enrollment
* No more than moderate TR as assessed by echocardiogram
Exclusion Criteria:
* Undergoing positive pressure ventilation (Bipap or invasive mechanical ventilation)
* Non-visible external jugular vein bilaterally (by visual examination or with traditional ultrasound examination)
* History of thrombosis in any of the following vessels bilaterally; external jugular vein, internal jugular vein, brachiocephalic vein or superior vena cava
* Skin lesions, vascular access sites or dressings covering neck and impeding access to the external jugular veins at the level of the muscle belly of the sternocleidomastoid muscle
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?

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?
