Several factors can influence PaCO2 levels, including:
Ventilation: Hypoventilation increases PaCO2, while hyperventilation decreases it. Metabolic Rate: Increased metabolic activity raises CO2 production. Lung Function: Conditions like COPD and asthma can impair CO2 elimination. Sedation and Anesthesia: These can depress respiratory drive, affecting PaCO2 levels.
