Simulating capnography in software on the METI emergency care simulator.

Area of Science:

• Medical Simulation
• Anesthesiology
• Biomedical Engineering

Background:

• Existing METI Emergency Care Simulators lack realistic CO2 monitoring for anesthesia training.
• Mannequin CO2 output does not accurately reflect simulated patient status.
• METI Waveform Display software limitations hinder capnography integration.

Purpose of the Study:

• To develop a software solution for simulating capnography monitoring in anesthesia simulators.
• To enhance the fidelity of simulated patient ventilation and CO2 waveforms.
• To improve the utility of emergency care simulators for advanced anesthesia training.

Main Methods:

• Developed a software application to generate realistic CO2 traces synchronized with mannequin ventilation (spontaneous or mechanical).
• Tested the software in a research study of advanced anesthesia monitoring displays.
• Validated the application in simulator-based training courses at two major medical centers.

Main Results:

• Participants successfully used the simulated monitor for intubation confirmation and airway event detection.
• Anesthesia simulation fidelity was significantly improved for training purposes.
• Previously incompatible anesthesia training scenarios became feasible with the enhanced simulator.

Conclusions:

• The developed software substantially increases the realism of anesthesia training scenarios.
• Improved capnography monitoring fidelity enhances the overall effectiveness of medical simulation.
• This solution offers a valuable tool for anesthesia education and research.
