Hi there,
first I would like to really appreciate your amazing work and your support you’re doing here! That’s really awesome. 🙂
I’m currently doing my first steps with Pulse and it’s Python bindings. At the moment I try to implement a VC-CMV ventilation to mimic a specific ventilator, but: that device has a setting for maximum inspiration pressure. So basically you set the respiration rate, the tidal volume, the I:E ratio and the maximum inspiration pressure, just in case your combination was too high and thus protecting the lungs.
As I saw you can create a manual MechanicalVentilator configuration; but then I have difficulties setting the tidal volume (as there is no property for setting that and I don’t have a clue on how to set that “by hand”) - on the other hand I’m super happy with SEMechanicalVentilatorVolumeControl and eMechanicalVentilator\_VolumeControlMode.ContinuousMandatoryVentilation - but then I would need to set a maximum p\_insp and the I:E ratio.
Do you have any hints for me on how to combine VentilatorVolumeControl and more specific settings?
Thanks a lot for your support!
Best regards,
Chris

All of our ventilator mode actions translate to a ventilator configuration, then our model just processes that configuration.
You can see how this is done in each of the C++ actions, [for example](https://gitlab.kitware.com/physiology/engine/-/blob/stable/src/cpp/cdm/system/equipment/mechanical_ventilator/actions/SEMechanicalVentilatorVolumeControl.cpp#L64)
You can also supply both a mode action and a configuration action together.
You can create a VC-CMV mode action to get the ventilator where you want it
Then create a configuration action setting the specific properties you want to modify, and the engine will bascially combine these configurations together.
I believe you want to change the `InspirationLimitPressure` in the configuration action
