A low cost ECG central station for intensive care

Area of Science:

• Biomedical Engineering
• Critical Care Medicine
• Medical Device Technology

Background:

• Intensive Care Units (ICUs) require continuous and reliable patient monitoring.
• Traditional bedside monitoring systems may have limitations in centralizing and displaying critical data.
• The need for integrated solutions to manage multiple physiological signals in critical care settings.

Purpose of the Study:

• To develop and evaluate a central station for electrocardiogram (ECG) monitoring in an ICU.
• To improve the selection, display, and alarm capabilities of ECG data from multiple bedside monitors.
• To assess the reliability and value of the developed system in a clinical intensive care environment.

Main Methods:

• Development of a microprocessor-based (8085) control unit and a mobile ECG station.
• Integration of a 4-channel ECG monitor, recorder, and computer terminal.
• Implementation of automatic display, hard copy, and audio alarms for critical ECG events.

Main Results:

• The central station allows selection and display of four ECGs from seven bedside monitors.
• Automatic display, hard copy, and audio alarms are triggered by any monitor detecting an alarm condition.
• The system has been operational 24/7 for three years, demonstrating consistent performance.

Conclusions:

• The developed ECG central station is a valuable and reliable instrument for intensive care environments.
• The system effectively enhances the management and surveillance of ECG data in ICUs.
• Continuous use confirms the system's utility and robustness in critical care settings.
