About this study
The purpose of this study is to examine the agreement between venous blood gas and arterial blood gas measurements in patients in the Intensive Care Unit.
Read the detailed description
Venous blood gas analysis may be an alternative to arterial blood gas analysis for acid-base status, reducing the need for frequent invasive arterial sampling. The objective of this study is to examine the agreement between ABG and VBG samples for all commonly used parameters (pH, pCO2 and bicarbonate) in a pathologically diverse ICU patient population, specifically analyzing multiple paired arterial and venous samples from each patient.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Venous blood gas analysisProcedure or surgery
When an ABG is deemed to be necessary as part of ICU management, a central venous sample will also be obtained with minimum delay (always < 2 minutes) between the samples. The samples will be analyzed by a blood gas analyzer as quickly as possible.
| Study group | Role | What they receive |
|---|---|---|
| 1 | Other | Not described Receives: Procedure: Venous blood gas analysis |
What is being measured
The primary outcome is the main question the study is designed to answer.
Agreement between venous and arterial blood gas measurements of pH, pCO2 and bicarbonate
Measured: Duration of Intensive Care Unit Admission

Questions about this trial
What is this clinical trial studying?
A study testing Venous blood gas analysis in people with Acid-Base Balance, run by Olive View-UCLA Education & Research Institute.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 15 Mar 2021. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
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?
Agreement between venous and arterial blood gas measurements of pH, pCO2 and bicarbonate (time frame: Duration of Intensive Care Unit Admission). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00569634, which also lists 14 linked publications.
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 15 Mar 2021.
