Composition. Inhaled air is by volume 78.08% nitrogen, 20.95% oxygen and small amounts include argon, carbon dioxide, neon, helium, and hydrogen. The gas exhaled is 4% to 5% by volume of carbon dioxide, about a 100 fold increase over the inhaled amount. ... 74.4% nitrogen.

Inhaled air contains approx 21% oxygen, 0.04% carbon dioxide and 79% nitrogen while exhaled air contains approx 16% oxygen, 4% carbon dioxide and also 79% nitrogen. The only difference between them is the varying levels of oxygen and carbon dioxide
