I see this on a Swiss team of pulmonary experts investigating acute mountain sickness and think of the research that’s been done that links this sort of oxygen exchange problem with asthma.

“…acute mountain sickness and the pronounced fall in oxygen saturation were not related to nocturnal breathing disturbances such as reduced or irregular and periodic ventilation, but more likely to impaired gas exchange in the lungs. ”

Asthma is such a stealer of the quality of life. It would be great to see the findings of this article applied to that research.
