A reduction in alveolar ventilation causes an increase in arterial PCO₂. The pH falls. In the short term, there is insufficient time for metabolic (renal) correction, so the bicarbonate concentration remains almost unchanged. This pattern is seen where there is a sudden reduction in ventilation, such as obstruction of the airway, overdose of sedative drugs or acute neurological damage.
