Airway Nitric Oxide in Space (Airway_Monitoring)
Principal Investigator
Research Area:
Environmental monitoring
Hyper- and hypobaric physiology
Pulmonary physiology
Species Studied
Scientific Name: Homo sapiens Species: Human

The goal is to define how much the exhaled nitric oxide (NO) is reduced with combined microgravity and reduced ambient pressure, and by what mechanisms. This is considered very useful for the monitoring of lung health in future exploration-class space missions. Even more important, by manipulating the alveolar uptake of NO to the blood (increased in microgravity) and the speed of diffusion of NO in the respiratory zone of the lungs (by reduced ambient pressure) this study will be able to more precisely define the location of NO formation for the benefit of the diagnostic use of exhaled NO on the ground.
