Arterial blood gas PaO2 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 = 0.000) lower PaO2 values in obese compared to non-obese patients at all time points. Although PaO2 values were lower in patients with, compared to patients without bronchospasm, the difference did not reach significance (P = 0.305). Within groups comparisons showed significant (P = 0.000) change of PaO2 values over time, as seen in the graph
