About this study
Official title: Comparison Study of ezCVP and CVP
Comparison of a non-invasive method of measuring central venous pressure to the conventional modality of invasive central venous pressure.
Read the detailed description
The conventional method used to measure central venous pressure has limitations since it is an invasive procedure that requires a central venous catheter. To overcome this challenge, a new technology to assess CVP non-invasively using an oscillometric method is being developed. It is called enclosed zone central venous pressure (ezCVP). A comparison study of ezCVP and CVP is needed to determine accuracy and reproducibility.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Non-invasive central venous pressureDevice
Also called ezCVP, CVPni
Non-invasive method to measure central venous pressure indicator
What is being measured
The primary outcome is the main question the study is designed to answer.
Non-invasive pressure indicator
Evaluate sensitivity and specificity of ezCVP indication based on the case where CVP is in a 'low range' (0 < CVP < 10 mmHg) or 'high range' (>= 10 mmHg)
Measured: 1-7 days
Secondary outcomes (2)
Direction of change
Correlate the directionality of ezCVP change to invasive CVP change over time (i.e., increasing, decreasing or remaining stable).
Measured: 1-7 days
Correlation with invasive CVP
Quantify the agreement between ezCVP (non-invasive) and CVP (invasive)
Measured: 1-7 days

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Non-invasive pressure indicator (time frame: 1-7 days). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 13 Feb 2026.
