Which of the following determines the fractional concentration of CO after 10 seconds of breath holding (F_ACO_T)? A) (F_AHe/F_IHe)$\times$ F_ICO B) Volume inspired divided by F_AHe/F_IHe C) Estimation of the ratio F_ICO/F_AHe D) Measurement of CO from an alveolar sample

Question

Quizplus · Accepted Answer

The correct answer involves directly measuring the concentration of CO (carbon monoxide) from an alveolar sample, as this method provides the most accurate and direct assessment of the fractional concentration of CO in the breath after holding it for a specified period.
