Sex: All

Ages: 18 Years – N/A

Healthy volunteers: No

Enrollment: 150

Sponsor: University of Minnesota

Summary

This study will establish the feasibility and preliminary validity of real-time oxygen delivery index (DO₂i) monitoring using noninvasive hemoglobin (SpHb, Masimo) and minimally invasive cardiac output (FloTrac, Edwards) in cardiac surgery patients.

Eligibility Criteria

Inclusion Criteria: * Adults ≥ 18 years undergoing cardiac surgery * Placement of pulmonary artery catheter with continuous cardiac output (CCO) as part of routine clinical care * Placement of arterial line with FloTrac as part of routine clinical care * Availability of ≥ 3 arterial blood gas samples at specified timepoints Exclusion Criteria: * Mechanical circulatory support planned or in use (IABP, Impella, ECMO) * Patients without BOTH pulmonary artery catheter with CCO and arterial line with FloTrac * Patients who are Research Opt-Out
