WebIn patients with more than one admission, the PaCO2 of one episode correlated with the PaCO2 on a subsequent admission, suggesting a role for individual variation in ventilatory control. With appropriate medical therapy, most patients with hypercapnia from acute asthma have rapid reversibility, and mechanical ventilation usually can be avoided. WebIn asthmatic patients, the relationship between arterial carbon dioxide tension (PaCO2) and FEV1, used as a measure of airway dysfunction, is not linear. Hypocapnia (low PaCO2) is the rule unless airway obstruction is severe, when mild hypercapnia may occur.1 The PaCO2 is an index of, and is inversely related to, ventilation. Mechanical airway obstruction ought to …
