The Pulmonary Function in Flight (PuFF) experiment was part of the Human Research Facility on the International Space Station. It included a manual breathing valve, flow meter, pressure-flow hoses, and syringes used by astronauts to test their breathing pressure and volume. As crew members breathed cabin air, their lung muscle strength and lung function were measured and computer-recorded to detect any changes in microgravity. Spacewalking astronauts also did the PuFF experiment before and after spending time outside in the lower-pressure spacesuits. The PuFF tests were designed to learn more about how the lungs may be affected by long stays in space and about the effects of gravity on lungs in general.

NASA transferred this experiment kit to the Museum in 2011.
