Hello, I'm an expert in the field of human physiology and environmental science. When discussing the amount of oxygen a person needs, it's important to consider various factors such as age, activity level, and health conditions. On average, an adult at rest inhales about 0.5 liters of oxygen per minute, which is roughly 7-8 liters per hour. However, this amount can increase significantly during physical activity or in response to certain health issues.
During respiration, the body uses oxygen to break down glucose and produce energy, a process that also generates carbon dioxide as a byproduct. The human body is highly efficient at utilizing the oxygen it receives, but it also has mechanisms to alert us when oxygen levels are low, such as the sensation of breathlessness or shortness of breath.
It's also worth noting that while oxygen is vital for life, too much oxygen can be harmful. Oxygen toxicity can occur if the body is exposed to high concentrations of oxygen over a long period, leading to potentially serious health issues.
In summary, the amount of oxygen a person needs can vary, but on average, it's about 7-8 liters per hour for an adult at rest. It's crucial to maintain a balance, as both insufficient and excessive oxygen levels can have adverse effects on health.

The air that is inhaled is about 20-percent oxygen, and the air that is exhaled is about 15-percent oxygen, so about 5-percent of the volume of air is consumed in each breath and converted to carbon dioxide. Therefore, a human being uses about 550 liters of pure oxygen (19 cubic feet) per day.
