Ventilator risk management using a programmed monitor

Area of Science:

• Biomedical Engineering
• Medical Informatics
• Critical Care Medicine

Background:

• Mechanical ventilation is a critical life support intervention.
• Effective quality control and risk management are essential for patient safety during ventilation.
• Existing systems may lack integrated real-time monitoring and automated data logging.

Purpose of the Study:

• To develop and evaluate a computer program for enhanced quality control and risk management in patients on mechanical ventilators.
• To improve the safety and efficiency of ventilator use in clinical settings.
• To provide real-time data display and automated reporting capabilities.

Main Methods:

• A computer program was developed for the Spacelabs PC Monitor interfaced with the Puritan-Bennett 7200a ventilator.
• The software performs pre-connection checks of ventilator hardware status, alarm statuses, and alarm limits.
• Post-connection, the program periodically polls for patient data, alarm conditions, and setting changes, logging data automatically.
• Real-time data display and post-session reporting (hard copy or disk) are available.

Main Results:

• The program successfully interfaces with the specified ventilator and monitor.
• Pre-connection checks prevent ventilator use in case of hardware failures or improper alarm settings.
• Continuous monitoring and automated data logging capture critical ventilation parameters and events.
• Clinicians can access real-time data and generate comprehensive reports.

Conclusions:

• The developed software significantly improves quality control and risk management for patients on mechanical ventilators.
• Automated pre-connection checks and continuous monitoring enhance patient safety.
• The system provides valuable data for clinical decision-making and documentation during mechanical ventilation.
