List laboratory findings.
Laboratory and microbiological studies: same as for the diagnosis of pneumonia.
ABG: e.g., ↓ PaO2
List imaging findings.
Imaging: The lung region in which the infiltrates are seen depends on the patient's position on aspiration.
Supine position: superior segment of the right lower lobe (most common site of aspiration)
Standing/sitting: posterior basal segment of the right lower lobe
Right lateral decubitus position: posterior segment of the right upper lobe or right middle lobe
