Area of Science:

  • Biomedical Engineering
  • Critical Care Medicine
  • Health Informatics

Background:

  • Severe arterial hypoxemia in Adult Respiratory Distress Syndrome (ARDS) patients requires precise mechanical ventilation management.
  • Standardizing ventilator therapy is crucial for improving outcomes in critically ill patients.

Purpose of the Study:

  • To develop and evaluate a computer-based patient advice system (COMPAS) for optimizing ventilator adjustments in ARDS.
  • To assess the clinical utility and user acceptance of COMPAS in a real-world setting.

Main Methods:

  • Implementation of a computer-based system (COMPAS) integrating respiratory care algorithms into the HELP hospital information system.
  • Clinical evaluation of COMPAS over 624 hours on 5 ARDS patients in a randomized trial, presenting therapy suggestions via bedside terminals.

  • Assessment of clinician adherence to computerized suggestions and user feedback through questionnaires.

    • Main Results:

    • COMPAS provided recommendations for 5 ventilation modes and various therapeutic adjustments for severe hypoxemia.
    • Clinical staff implemented 84% of the computerized therapy suggestions during the trial.
    • 86% of clinical users found the COMPAS system to be potentially valuable.

    Conclusions:

    • COMPAS, a computer-based ventilatory therapy advice system, demonstrates feasibility for standardizing ventilator management in critically ill ARDS patients.
    • The system shows potential for improving the consistency and quality of care for patients with severe arterial hypoxemia.
    • High user acceptance suggests a positive impact on clinical practice and patient outcomes.
