Add 2 modes of ventilation that could be useful for Covid-19

• Pressure Control mode
  • Inputs
    • PIP- Peak Inspiratory Pressure (cmH2O)
    • PEEP- Positive End Expiratory Pressure (cmH2O
    • BPM - Breaths per minute
    • FiO2 
  • Output
    • Directs user as to flow rate setting for oxygen

• APRV- Airway Pressure Release Ventilation
  • Inputs
    • P-high (cmH2O)
    • P-Low (cmH2O)
    • T-high (seconds)
    • T-Low (seconds)
    • FiO2
  • Output
    • Directs user as to flow rate setting for oxygen

Add startup checks for the ventilator:

• Tightness test
  • Turn on blower to max and ensure that the pressure increases to static pressure and hold for 1 minute to verify that flow does stop.
• Flow meter offset calibration
  • The tubing and system will have air capacitance that needs to be subtracted to get correct tidal volumes.  Pump up the system to max pressure and create a flows table.  Do this 5 times and take average.

Add Alarms to ventilator- alarms to be published to cloud and sent out be sent out to hospital staff.
