How altitude affects outcomes for children with acute respiratory distress
This project will see if higher altitude and differences in hospital critical-care resources change outcomes for children (1 month–18 years) with PARDS who need invasive mechanical ventilation.
-
Acetazolamide and plasma volume changes at high altitude
This study will see if acetazolamide helps prevent early plasma volume loss and related altitude symptoms in healthy adults who normally live at low altitude.

Measuring heart and lung function after going to high altitudes
This study is trying to see how high altitudes affect heart and lung function in people, especially those with existing heart problems, by observing their responses in a cable car setting.
