Why breathing 100% pure oxygen would be fatal within days
In short: Oxygen is essential for life, yet breathing it at full concentration is toxic. This video explores the science of hyperoxia, the destructive power of free radicals, and why the nitrogen in our air is vital for survival.
The video examines oxygen toxicity, or hyperoxia, explaining how reactive oxygen species (ROS) can destroy cells. It details the biological mechanisms of how hemoglobin transports oxygen and how antioxidants work to protect the body.
While our air contains only 21% oxygen, the remaining 78% nitrogen plays a critical role in maintaining lung function. The video explains how partial pressure helps keep the lungs inflated like spongy balloons and why breathing pure oxygen could lead to lung collapse and damage to the nervous system.
