Final answer:
COPD patients may have elevated pCO2 levels due to impaired ventilation.
Step-by-step explanation:
COPD, or Chronic Obstructive Pulmonary Disease, is a lung condition that affects the ability to breathe. While there is no specific common serum CO2 value for all COPD patients, the blood gas analysis parameters can provide insight into the status of acid-base balance in these patients. In COPD patients, the pCO2 levels are frequently elevated due to impaired ventilation. It is important to note that the values can vary depending on the severity of the condition and individual patient factors.
