Patient 2 was removed from the analyses because of our inability to aspirate peritoneal fluid. CPIS, Clinical Pulmonary Infection Score; HAP, hospital-acquired pneumonia; L, left; LLL, lower left lobe; LRL, lower right lobe; MV, mechanical ventilation; PaO₂/FiO₂, arterial partial pressure of oxygen/fraction of inspired oxygen; R, right; VAP, ventilator-associated pneumonia.
