What do you think are the risks of cross contamination in this setup (let's say, just for 2 people sharing one unit)? She mentions how, in a situation where you'd have to use this, they'd have the same infection. What if they have different secondary infections or different types of pneumonia?

The example of the Vegas disaster is different because they were all gunshot victims; they were healthy, but wounded. I hope we would never need to see if these would be effective.

MD here. There is an inhalation and exhalation tube for each patient; the exhalation tubes would be in continuity using the described configuration. However, at least for part of the transmission route, viral particles would have to move against flow. So there is likely some cross-contamination.

All that being said in the situation where this is deployed I think it would be a risk most providers would take.
