<jats:p> The physiological content of N<jats:sub>2</jats:sub> multibreath washout testing has been questioned due to N<jats:sub>2</jats:sub> indirect measurement accuracy and N<jats:sub>2</jats:sub> blood solubility. With direct measurement of N<jats:sub>2</jats:sub> and twice as soluble argon, we show that these effects are largely outweighed by ease of use. </jats:p>
