Short title	Five percent CO₂ for 20 minutes then 9 percent for 2 minutes gives FED 1.01.
Image title	Line chart of accumulated fractional effective dose (FED) against time in Purser's worked example. 5% CO2 for 20 minutes accumulates 0.0282 per minute, reaching 0.564 at 20 minutes; 9% CO2 for the next 2 minutes accumulates 0.2247 per minute, reaching FED 1.01 at 22 minutes. A dashed line marks FED 1. A note says this is a model example, not a universal 22-minute limit.
