Plethysmography as a Useful Intraoperative Monitor
An observational study of Cardiovascular Diseases, run by University of Virginia at 1 site in United States.
Trial summary
Data from both the traditional invasive cardiac monitors and the Nonin will be collected simultaneously. The investigators will analyze Nonin data for peak and trough variation with respiration, area under the curve, time from trough to peak, and slope, and compare these to data collected from the invasive monitors to… Read more about this study

About this study
Data from both the traditional invasive cardiac monitors and the Nonin will be collected simultaneously. The investigators will analyze Nonin data for peak and trough variation with respiration, area under the curve, time from trough to peak, and slope, and compare these to data collected from the invasive monitors to look for correlations in clinically important parameters such as blood pressure, central venous pressure, cardiac output, etc.
Read the detailed description
After obtaining written consent to participate, the standard of care arterial line and PA catheter will be placed pre-operatively. The investigators will attach the Nonin pulse oximeter, as a second pulse oximeter probe, to patients undergoing surgical procedures which already require invasive cardiac monitors (arterial line, pulmonary artery catheter, etc). Data from both the traditional invasive cardiac monitors and the Nonin pulse oximeter will be collected as electronic files. Once both files are compiled they will be de-identified.
The investigators will also record medications and IV fluids given during surgery.
The Nonin Pulse Oximeter is clinically marketed for this indication
The investigators will analyze Nonin data for peak and trough variation with respiration, area under the curve, time from trough to peak, and slope, and compare these to data collected from the invasive monitors to look for correlations in clinically important parameters such as blood pressure, central venous pressure, cardiac output, etc.

What is being measured
The primary outcome is the main question the study is designed to answer.
waveform variation of the Nonin pulse oximeter compared with that of the arterial catheter
The investigators will analyze Nonin data for peak and trough variation with respiration, area under the curve, time from trough to peak, and slope, and compare these to data collected from the invasive monitors to look for correlations in clinically important parameters such as blood pressure, central venous pressure, cardiac output, etc.
Measured: during surgery

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Data from both the traditional invasive cardiac monitors and the Nonin will be collected simultaneously. The investigators will analyze Nonin data for peak and trough variation with respiration, area under the curve, time from trough to peak, and slope, and compare these to data collected from the invasive monitors to look for correlations in clinically important parameters such as blood pressure, central venous pressure, cardiac output, etc.

Questions about this trial
What is this clinical trial studying?
An observational study of Cardiovascular Diseases, run by University of Virginia at 1 site in United States.
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 1 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 30 Apr 2013. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
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?
waveform variation of the Nonin pulse oximeter compared with that of the arterial catheter (time frame: during surgery). 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 30 Apr 2013.
