What is the most common hyperbaric respiratory issue?
Barotrauma
Why does ventilation increase in high altitude?
Hypoxia is sensed by peripheral chemoreceptors and they increase the breathing

Highest Mortality
Return to low altitude FAST

How can increased ventilation help?
You can raise the PAO2 without changing FIO2
