From working on the environmental sensor side of things, I'd concur. The VOCs will be able to be picked up, but the cross talk will be huge across other VOCs that don't themselves indicate pneumonia. There isn't one VOC, there's thousands. False positives are written all over this. This is the very same approach Theranos went. On a science level, sure, technically possible maybe. You'll even get boolean outputs. But on an engineering and regulatory level, you're in for a world of pain without the spectral tech that is still 2-5 years away before this is worth basing human lives on.
