Collecting Exhaled Breath from Flu Patients Using the Gesundheit II Machine (image) University of Maryland Share Print E-Mail Caption The Gesundheit II machine collects the breath exhaled from flu sufferers. Study volunteers sit for 30 minutes with their heads in the horizontal cone attached to the machine, which sucks in the air around their heads to collect tiny airborne droplets generated deep in the lungs. Researchers can then analyze the aerosols for the presence and quantity of virus.
