Arterial blood gas PaCO2 values (Mean, SD) in non-obese patients versus obese patients without bronchospasm versus obese patients with bronchospasm over time. Between groups comparisons showed significantly (P = 0.005) higher PaCO2 values in obese compared to non-obese patients, and significantly (P = 0.012) higher PaCO2 values in patients with bronchospasm compared to patients without bronchospasm at all time points. Within groups comparisons showed significant (P = 0.015) change of PaCO2 values over time, as seen in the graph
