Which of the following lead to an increased end-tidal PCO₂?
1) Decreased effective ventilation
2) Increased metabolic rate
3) Decreased minute ventilation
4) Exercise

Question

Quizplus · Accepted Answer

End-tidal PCO2 increases with decreased effective ventilation and decreased minute ventilation because less CO2 is being exhaled. An increased metabolic rate also raises CO2 production, thus increasing end-tidal PCO2.
