In Acute exacerbation of COPD, there is shortness of breath. Should we consider it as increase PaCO2 or decrease PaCO2 condition ? as there is shortness of breath.

hey

COPD pts have retention of CO2...so PaCO2 increases causing respiratory acidosis which our body compensates by metabolic alkalosis.Pls correct me if I am wrong
