Background and Aims: Simulation-based medical education is effective for developing and improving critical care-related clinical skills training and reducing patient safety threats. The present study aimed to describe the technological approach of building and evaluating a prototype of a Lung Box (LB) mechanical ventilation simulator.
Materials and Methods: In this practical study with an analytical approach, the device's body, constructed from 5 mm plexiglass sheets, occupies a respiratory circuit, an airflow obstruction system, a pressure gauge manometer, a spring-loaded manual system to apply limits on the bag inflation range, a tidal volume measurement system, a respiratory trigger simulator system, and a four-layer accordion-style plastic bag assembly that can be inflated and deflated with air. Additionally, there is a user manual storage box along with it.
Results: The design and drawing of the device's map were performed with AutoCAD software, and the parts were assembled after laser cutting. The device was connected to the ICU ventilator, and the respiratory mode of continuous forced ventilation was selected. Prior to ventilation, the tidal volumes were selected to be 0.60, 0.55, 0.50, 0.45, and 0.40 ml, and respiratory rates were set as 18, 15, 12, and 9 bpm. The simulation of the respiratory trigger was performed with different values of flow sensitivity (0.05-15 lit/min). There was no statistically significant difference (P>0.05) in terms of the reproducibility of the values of the selected variables for the test Lung (TL) with those chosen for LB.
Conclusion: In this technical study, a prototype educational mechanical ventilation simulator was developed and functionally tested using the concepts of fluid dynamics and respiratory physiology. Compared with conventional TL, this device is accurate and efficient enough.
