Comparative Performance of Pulmonary Ultrasound, Chest Radiograph, and CT Among Patients With Acute Respiratory Failure*

Objectives: The study goal was to concurrently evaluate agreement of a 9-point pulmonary ultrasound protocol and portable chest radiograph with chest CT for localization of pathology to the correct lung and also to specific anatomic lobes among a diverse group of intubated patients with acute respiratory failure. Design: Prospective cohort study. Setting: Medical, surgical, and neurologic ICUs at a 670-bed urban teaching hospital. Patients: Intubated adults with acute respiratory failure having chest CT and portable chest radiograph performed within 24 hours of intubation. Interventions: A 9-point pulmonary ultrasound examination performed at the time of intubation. Measurements and Main Results: Sixty-seven patients had pulmonary ultrasound, portable chest radiograph, and chest CT performed within 24 hours of intubation. Overall agreement of pulmonary ultrasound and portable chest radiograph findings with correlating lobe (“lobe-specific” agreement) on CT was 87% versus 62% (p
