Multivariable Model of Odds of Postoperative Pneumonia

Characteristic Odds Ratio (95% CI) P-Value
PIP ≤ 30 cmH2O 0.45 (0.22–0.92) 0.03
Postoperative Ventilation < 6 hours 0.47 (0.26–0.87) 0.02
Documentation of Progressive Postoperative Ambulation 0.08 (0.04–0.17) <0.001
Use of Postoperative Bronchodilator 4.83 (2.20–10.7) <0.001

Abbreviation: Inspiratory Pressure (PIP)

For PIP, patients who received PIP ≤ 30 cmH2O were compared to patients who received PIP > 30 cmH2O (reference group)
