Virtual instruments simulate patient responses during extracorporeal circulation (ECC), enabling real-time monitoring and adjustments to perfusion parameters for improved patient care.

Area of Science:

  • Biomedical Engineering
  • Medical Simulation
  • Cardiovascular Physiology

Background:

  • Extracorporeal circulation (ECC) requires precise management of physiological parameters.
  • Simulating ECC processes can enhance understanding and training for clinicians.

Purpose of the Study:

  • To develop virtual instruments for simulating patient responses during ECC.
  • To enable real-time monitoring and dynamic adjustment of perfusion variables.

Main Methods:

  • Computer simulation incorporating hydraulic, thermal, and biochemical phenomena.
  • Integration of virtual ECC devices (oxygenators, pumps, heat exchangers).
  • Real-time monitoring of physiological variables and alarm systems.

Main Results:

  • Simulated real-time monitoring of arterial/venous pressures, flow rates, urine production, and temperature.
  • Monitoring of blood gas parameters (pO2, pCO2, pH, HCO3) and oxyhemoglobin saturation.
  • Implementation of a drug model for vasodilator and diuretic effects, with run-time parameter adjustment.

Conclusions:

  • The virtual ECC system provides a comprehensive simulation environment for training and research.
  • Real-time interaction and parameter modification enhance the utility of the simulation.
  • This tool can aid in optimizing ECC management and patient safety.
