How Does COPD Affect Arterial Blood Gases? In all patients with COPD there is the decrease of pH and PaO2 and an increase of PaCO2 during follow-up period that indicates that airflow limitation is progressive but in patients taking regular therapy treatment during remissions and exacerbations of illness both pH and PaO2 are statistically significantly
