A virtual ventilator simulation system was created for healthcare professionals to learn respiratory mechanics and mechanical ventilation modes. This interactive tool demonstrates pressure and flow dynamics during various breathing conditions and ventilator settings.

Area of Science:

  • Biomedical Engineering
  • Medical Simulation
  • Respiratory Physiology

Background:

  • Mechanical ventilation is crucial for respiratory support.
  • Understanding respiratory mechanics and various ventilation modes is essential for healthcare professionals.
  • Novice clinicians require effective training tools to grasp complex ventilation concepts.

Purpose of the Study:

  • To develop an interactive "virtual ventilator" simulation system.
  • To demonstrate respiratory system dynamics, including pressure and flow.
  • To provide a self-training tool for inexperienced healthcare professionals on spontaneous breathing and ventilation modes.

Main Methods:

  • Developed a simulation system with modules for respiratory, spontaneous breath, and ventilator functions.

  • Modeled the respiratory system using resistances and compliances.
  • Integrated a controller to manage interactions between patient breathing and ventilator settings.

    • Main Results:

    • The system, built with HTML, VBScript, and ActiveX, simulates various ventilation modes (CMV, SIMV, PSV, PCV, PRVC, BiPAP, etc.).
    • Users can define spontaneous breathing parameters (frequency, amplitude, patterns).
    • Visualizes airway pressure, flow, and volume dynamics during mechanical ventilation with or without spontaneous breathing.

    Conclusions:

    • A web-based application was successfully developed for simulating respiratory mechanics.
    • The system effectively demonstrates the fundamental principles of mechanical ventilation modes.
    • The virtual ventilator serves as a valuable self-training resource for healthcare professionals.
