You covered many of these topics in the readme (great job btw!!), posting here for reference..

Ventilation performance

• Pressure controlled
• Inspiratory pressure up to 40cmH2O
• Expiratory pressure up to 20cm H2O
• Respiratory rate from 5-40 breaths a minute
• Measurement of tidal volume at the Y piece
• FiO2 from 20% to 100% in discreet steps of 10%
• Triggering—timed or patient-effort triggered
• Connect to standard masks and tubes
• Connect to standard oxygen connectors
• Accuracy (<10% for volumes and pressure, to 1 breath a minute for rate
• Can work on internal battery for >180 min
• Oxygen concentration NOT mandatory, recommended

Patient safety

• Alarms or limits
• Minute Ventilation (low/High) alarm
• Peak pressure, Low expiratory pressure and/or disconnection alarm
• Low expiratory pressure
• Oxygen concentration
  -Non-rebreathing valves

Device safety

• Electrical safety requirements
• Fire safety (i.e., pure O2 flowing)

Infection control

• HEPA filtered inlet and outlet
• Easy-to-clean surfaces

Design Requirements

User Interaction

• Simple to use--must not require specialized training
• Modular, with known failure potential for each component
• Easy to maintain (related to modularity)
• Settings legible from 1m
• Clear flow directions

Material and Manufacturability

• Widely available material (e.g. 3D printable filaments, plastic/metal sheets)
• Can be built locally using either simple tools or rapid prototyping (i.e. 3D printing, CNC, etc.)
• Only eligible material allowed (see list to exclude)
• Operational requirements
• Both 110V and 220V

IMHO

ventilators = lives

is there enough participation in the community to rapidly build a low cost (~$200-$300 USD) high quality ventilator system with reusable/replaceable parts that can be sourced from local hardware stores that meets these standards?
