If so, excellent!OTOH this sounds like a far superior solution to the problem addressed by the ventilator. Might very well save lives that a ventilator can’t - and (if it isn’t being overhyped) might systematically deliver superior outcomes.
I notice that an oxygen tank is part of the system; they make battery-operated units which can extract concentrated O2 out of the air which are much more compact than an oxygen tank.
Might make life livable longer for COPD patients . . .
Not to mention the claimed reduction in the need for medical personnel . . .
