Delphi is an opensource device configurable for use in emergency medical ventilators as either a flexible user interface module or (in the future) as a complete control system with user interface. Delphi is implemented as an oversized custom Arduino shield designed to be agnostic to the details of the air handling mechanism, sensing system, and other mechanical and electrical details of ventilators constructed for emergency use. As such, it is usable in whole or in part within virtually any emergency ventilator design.

The Delphi implementation is guided by a belief that the global engineering and design community needs to modularize and standardize our efforts as we seek to develop safe opensource ventilators that can be used to help address possible equipment shortages during the coronavirus pandemic. Our initial contribution to this ecosystem is the Delphi User Interface, a flexible, clinician-validated user interface, comprising system hardware and software, and a simple communications interface, which can be easily incorporated into other emergency ventilator projects. The Delphi user interface is intended to provide a clinician-validated standard user interface that is usable across a wide range of emergency ventilator designs. By adopting the Delphi user interface, emergency ventilator design teams simplify the scope of their own project and help reduce barriers to adoption and use of their emergency ventilator by health care providers. With this release (v0.1.3), the Delphi User Interface design is complete.
