  • HAP/VAP incidence was defined as number of patients with positive sputum cultures (expectorated or aspirate) that required treatment. Change in SF ratio=SF ratio at day 7–10–SF ratio at day 0.

  • CXR, chest X-ray; HAP, hospital-acquired pneumonia; HR, heart rate; ICU, intensive care unit; LOS, length of stay; RALES, Radiographic Assessment of Lung Edema Score; RR, respiratory rate; SF ratio, saturation to fraction ratio; VAP, ventilator-associated pneumonia.
