Drowned Lung Model
COPD causes irreversible damage to the lungs, and this model provides a window into the wheezing, chronic cough that COPD sufferers endure. The lifelike model of a damaged lung steeps in slimy, simulated phlegm. When the jar is picked up, a voice module emits a gurgling, gasping cough, revealing the drowning sensation COPD experience as they gasp for air. Jar is 18 cm tall.
