    A novel inline PEEP valve design for differential multi-ventilation
    (Elsevier, 2020-07-10) Bunting, Leonard; Roy, Steven; Pinson, Hannah; Greensweig, Tobin; Medicine, School of Medicine
    Background: Ventilator sharing is one option to emergently increase ventilator capacity during a crisis but has been criticized for its inability to adjust for individual patient needs. Newer ventilator sharing designs use valves and restrictors to control pressures for each patient. A key component of these designs is an inline Positive End Expiratory Pressure (PEEP) Valve but these are not readily available. Creating an inline PEEP valve by converting a standard bag-valve-mask PEEP valve is possible with the addition of a 3D printer collar. Methods: This was a feasibility study assessing the performance and safety of a method for converting a standard PEEP valve into an inline PEEP valve. A collar was designed and printed that covers the exhaust ports of the valve and returns exhaled gases to the ventilator. Results The collar piece was simple to print and easily assembled with the standard PEEP valve. In bench testing it successfully created differential pressures in 2 simulated expiratory limbs without leaking to the atmosphere at pressures greater than 60 cm of H2O. Conclusion: Our novel inline PEEP valve design shows promise as an option for building a safer ventilator sharing system.

    Using the Co-design Process to Build Non-designer Ability in Making Visual Thinking Tools
    (2020) Shope, Wendy; Hong, Youngbok
    This research is a case study of using co-design as a way of assisting the capacity building process for an Indianapolis-based community organizer. The community organizer seeks to develop a visual thinking tool for enhancing her engagement with community participants. Community organizers face a wide array of complicated challenges, addressing these kinds of challenges and social issues calls for innovative and inclusive approaches to community problem solving. The author hopes this case study will showcase itself as an example of leveraging design thinking and visual thinking to support and equip more first-line workers who are non-designers to do their community jobs with a more creative problem-solving approach.
