HEMO-INTEGRA: Integrated Intraoperative Hemodynamic Monitoring During Cardiac Surgery With Cardiopulmonary Bypass - A Pilot Study (HEMO-INTEGRA)

June 27, 2026 updated by: Hernán Darío Castro Arias

HEMO-INTEGRA: Feasibility and Description of an Integrated Intraoperative Hemodynamic Monitoring System for Cardiac Surgery With Cardiopulmonary Bypass - A Pilot Observational Study

HEMO-INTEGRA is a software system that integrates four domains of intraoperative hemodynamic monitoring in a single dashboard during cardiac surgery with cardiopulmonary bypass (CPB): (1) ventricular-arterial coupling (VAC) analysis using the Balan 2026 method; (2) tissue perfusion and oxygen delivery (EPOC module with Q10 temperature correction); (3) neuromonitoring (NIRS/BIS); and (4) systemic venous congestion assessment via VExUS-TEE (Waldron 2024 method).

This pilot observational study evaluates the feasibility and completeness of data capture using HEMO-INTEGRA across five perioperative time points (T0: pre-CPB; T1: early CPB; T2: mid-CPB; T3: rewarming; T4: post-CPB) in adult patients undergoing elective cardiac surgery at Clinica Medellin Sede Occidente, Medellin, Colombia.

The system operates in parallel with standard monitoring and does not modify clinical management. No additional procedures are performed on participants beyond standard of care.

Cohorts and Interventions

Group / Cohort
HEMO-INTEGRA Cohort

Adult patients undergoing elective cardiac surgery with cardiopulmonary bypass monitored with the HEMO-INTEGRA integrated hemodynamic monitoring system across five intraoperative time points (T0 to T4).

Intervention Name : HEMO-INTEGRA v2.0 Software system for integrated intraoperative hemodynamic monitoring integrating ventricular-arterial coupling (Balan 2026), tissue perfusion (EPOC/Q10), neuromonitoring (NIRS/BIS), and venous congestion (VExUS-TEE). Operates in parallel with standard care without modifying clinical management.
