Tidal volume (TV) is the amount of air breathed in with each normal breath. The average tidal volume is 0.5 litres (500 ml). Minute ventilation (VE) is the total volume of air entering the lungs in a minute.
How long can you survive in an airtight room?
That is roughly 116.5 hours, or 4.9 days. If the room is entirely oxygen, then we have 34,951.09 minutes to live: 582.52 hours or 24.3 days. In both scenarios, you’ll die of dehydration before you die of suffocation or starvation. The average person can only go 3 days, 72 hours, without water.

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.
