SpletThis leads to a rise in pCO2. With an acute asthmatic attack, even though the alveoli are functioning normally, there may be enough upper and middle airway obstruction to block alveolar ventilation, leading to CO2 retention. Increased pCO2 is caused by: Pulmonary edema Obstructive lung disease Decreased pCO2 is caused by: Hyperventilation Hypoxia SpletPaco2 is the ideal alveolar carbon dioxide tension.
