An interventional study of Retia Medical Long Time Interval Analysis in Hypotension, sponsored by University of Virginia. Status unknown at 1 site in United States. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2015-06-16.
Sponsored by University of Virginia · Not applicable, Interventional, and Diagnostic
A group of engineers at Michigan State developed a novel waveform analysis technique ("Long Time Interval Analysis" [LTIA]) that attempts to estimate cardiac output non-invasively. Retrospective comparison of LTIA to invasive techniques (e.g. thermodilution) suggest acceptable agreement. Thus, a prospective trial of LTIA is warranted. This study compares LTIA to a validated measure of cardiac output - esophageal Doppler monitoring.

Exclusion Criteria:
Patients in the LTIA Group (all patients) will have blood pressure recorded continuously. LTIA will be used to measure stroke volume and cardiac output after the completion of data collection
Device: Retia Medical Long Time Interval Analysis
Retia Medical "Long Time Interval Analysis" will be used to analyze the blood pressure tracing of patients having surgery who have an arterial catheter
Pearson Correlation Coefficient
Correlation between change in CO from LTIA vs. change in CO from esophageal Doppler
Time frame: Data collected in first 20 minutes of anesthesia/surgery will be recorded; Pearson correlation coefficient will be calculated after all 60 subjects have been enrolled
