Can you survive in 100% oxygen?
Can you survive in 100% oxygen? Absorption atelectasis due to washout of N2 can lead to collapse of parts of the lung in the event of air trapping. 100% oxygen can be tolerated at sea level for about 24–48 hours without any serious tissue damage.
What is the lowest oxygen level before death?
Once the level of oxygen goes below 15 percent, serious symptoms of hypoxia begin to show up, which means that someone is risking serious injury or even death. At 10 percent oxygen concentration, somebody has minutes or seconds to survive.
