House Staff Quality Improvement and Patient Safety Conference (2020-)

• Experts from the Thomas Jefferson University Health Design Lab met with Emergency Medicine and Anesthesia physicians and local engineers
• A design was envisioned in which 3-D printed connectors could be created to add an additional HEPA Filter as shown in Figure 1
• STL Files for the adapters were created based on standard HEPA filter diameters and 3-D printed
• The second HEPA filter was easily assembled by novice users using the adapters
• Ventilation adequacy using the double HEPA filter ambu-bag was similar to single HEPA filtered ambu-bag ventilation based on observed inflation of a test lung
