This study introduces an intelligent ventilator system with software modules for stable patient lung condition management. The system uses two controllers for diagnosis, setting adjustments, and real-time control, aiding clinical care.

Area of Science:

  • Biomedical Engineering
  • Medical Device Technology
  • Intelligent Control Systems

Background:

  • Mechanical ventilation is crucial for respiratory support in critical care.
  • Current ventilator systems require precise management for optimal patient outcomes.
  • Intelligent control systems offer potential for enhanced ventilator performance and safety.

Purpose of the Study:

  • To develop and evaluate an intelligent ventilator system with modular software controllers.
  • To assess the system's ability to manage ventilator operation based on patient lung conditions.
  • To determine the stability and efficacy of the proposed intelligent system.

Main Methods:

  • A novel ventilator system integrating intelligent software modules was designed.

  • Two controllers were utilized: a personal computer for diagnostics and settings, and a microprocessor for real-time ventilator control.
  • An artificial lung model simulating patient respiratory conditions was employed for system testing.

    • Main Results:

    • The intelligent ventilator system demonstrated stable responses to simulated patient lung conditions.
    • The system effectively adjusted ventilator settings based on diagnostic information and real-time feedback.
    • Consistent and reliable performance was observed during testing with the artificial lung model.

    Conclusions:

    • The proposed intelligent ventilator system, with its modular software, offers a stable and effective approach to managing patient respiratory conditions.
    • This technology has the potential to significantly assist clinicians in patient care and ventilator operation management.
    • Further clinical validation is warranted to explore the full impact of this intelligent system in critical care settings.
