What happens in chronic hypercapnia?
1) The central chemoreceptive response to CO₂ is decreased.
2) The cerebrospinal fluid pH is restored to normal.
3) Responsiveness to increased CO₂ is decreased.

Question

Quizplus · Accepted Answer

In chronic hypercapnia, the body adapts to the elevated levels of CO2. The central chemoreceptors' response to CO2 is decreased, allowing the body to tolerate higher levels of CO2. Additionally, mechanisms such as renal compensation help restore cerebrospinal fluid pH to normal, despite the elevated CO2 levels. This adaptation also leads to a decreased responsiveness to further increases in CO2, as the body's baseline has shifted to accommodate the chronic condition.
