Altitude Exposure
As we leave Earth's surface and the spacecraft gains altitude, so our circulatory and respiratory systems need to adjust physically to pressure changes. This is why commercial airlines gradually climb to 30,000 feet and the cabin pressure adjusts with the change in altitude. In commercial spaceflight, you will obviously far exceed 30,000 feet in much less time! We will cover how to deal with the rapid change in altitude and possibilities of hypoxia and hyperventilation with proper breathing.
