to store data immediately. Use this time to adjust dilution flow in order to achieve a CO2% that remains
between 0.5% and 1.5% (best compromise to avoid patient hyperventilation while maintaining accuracy).
Note: Hyperventilation usually occurs during the first few minutes of the test; avoid adjusting dilution flow
until patient is comfortably relaxed. Measured values immediately after dilution flow changes are not
reliable; Average interval should not include dilution flow adjustments.
