EtCO2 fraction

I’m running the Pulse 3.0 in Java with the Soldier@0s.json state file. I have a data request for EtCO2 like this:

SEDataRequest etco2 = new SEDataRequest();
etco2.setCategory(eCategory.Physiology);
etco2.setPropertyName("EndTidalCarbonDioxideFraction");
etco2.setUnit("unitless");
dataRequests.getRequestedData().add(etco2);

When I get the data while the engine is running, this value hovers between 0.045 and 0.046, which seems very low. My understanding is that normal is 35-45% (0.35-0.45), which is an order of magnitude higher.

Is this a bug, or am I doing something wrong?

That seems like the correct values. The accepted standard healthy EtCO2 values are 35mmHg-45mmHg, which equivalent to ~4%-6% or 0.04-0.06. You probably want to get “EndTidalCarbonDioxidePressure” with unit of “mmHg”.

You are right! Thanks for helping me find my mistake :slight_smile:

Btw, is there a comprehensive list of what properties can be requested? I was looking at this and got myself confused. But even if I had noticed my error, I wouldn’t have known about this other property.

With the correct data request, I’m getting a value between 34 and 35, which still seems slightly low, but maybe the soldier patient falls outside of normal because he’s unusually fit or something?

I tried the links, but I get 403 permission denied errors.

Sorry about that
Try now, had to push a fix to the site
(Let us know of any other issues on the site if you see anything)

That’s working. Thanks!
