• Cardiogenic pulmonary edema.
• Patients with severe facial deformities, facial trauma, or severe thoracoabdominal trauma that precludes prone positioning ventilation.
• Mid to late pregnancy.
• Patients with a history of malignancy or other irreversible diseases/conditions, including those in the terminal stage.
