: They recorded the first-ever physiological measurements on the summit. They found that climbers' bodies hyperventilate so drastically that the carbon dioxide in their lungs drops to nearly impossible levels (around 7.5 mmHg), which is what actually allows oxygen to reach the blood.

John B. West is often called the "summit" of respiratory physiology, not just for his academic brilliance but for literally taking his laboratory to the top of the world. His career is a rare blend of and extreme physical exploration . 1. The Radioactive Breakthrough

: He proved for the first time that blood flow is strikingly unequal due to gravity.

West’s most legendary feat was leading the . He wanted to answer a fundamental question: How is it possible for humans to survive where oxygen levels are at the absolute limit of tolerance? .

In the late 1950s, while at Hammersmith Hospital in London, West gained access to one of the first medical cyclotrons. He used —a radioactive isotope with a half-life of only two minutes—to track how blood flowed through the human lung.

Cool Everglades wants to make your searches as relevant as possible. That's why we offer many ways to help you find the right experiences for you.

On some pages, you can select how to sort the results we display and also use filter options to see only those search results that meet your chosen preferences. You'll see explanations of what those sort options mean when you select them.

If you see a Badge of Excellence label, the award is based on average review ratings, share of bookings with a review, and number of bookings through Cool Everglades over a 12-month period.

The importance of any one factor over any other in a sort order varies, and the balance is constantly being reviewed and adjusted. We're always updating our systems and testing new ways to refine and improve your results to make them as relevant as possible to meet your needs.
